All electrical appliances work by passing an electric current through them, which additionally heats the conductors and equipment. In this case, in normal operation, a balance is created between the increase in temperature and the removal of part of it into the environment.

In case of violations of the quality of the contacts, the conditions for the passage of current worsen and the temperature rises, which can cause a malfunction. Therefore, in complex electrical devices, especially on high-voltage equipment of energy enterprises, periodic monitoring of the heating of current-carrying parts is carried out.

For devices under high voltage, measurements are carried out by a non-contact method at a safe distance.

Principles of remote temperature measurement

Any physical body has a movement of atoms and molecules, which is accompanied. The temperature of the object affects the intensity of these processes, and its value can be judged from the value of the heat flux.

Non-contact temperature measurement is based on this principle.

An inspection source with a temperature "T" radiates a heat flux "F" into the surrounding space, which is perceived by a thermal sensor remote from the heat source. After it, the signal converted by the internal circuit is displayed on the information board "I".

Instruments for measuring temperature, which measure it by infrared radiation, are called infrared thermometers or the abbreviated name "pyrometers".

For their accurate operation, it is important to correctly determine the measurement range on the electromagnetic wave scale, which is approximately 0.5–20 µm.

The error of pyrometers depends on a complex of factors:

1. the surface of the observed area of ​​the object must be in the direct field of view;
2. dust, fog, steam and other objects between the thermal sensor and the heat source weaken the signal, as well as traces of contamination on the optics;
3. the structure and state of the surface of the body under study affect the intensity of the infrared flux and the readings of the temperature meter.

Does the influence of the third factor explain the graph of the change in the emissivity? from the wavelength.

The infrared radiation capacity Фs of the black material is taken as the basis for comparing other products and is taken equal to 1. The coefficients of all other real substances ФR become less than 1.

In practice, pyrometers recalculate the radiation of real objects to the indicators of an ideal radiator.

The measurement is also affected by:

the wavelength of the infrared spectrum, which is measured;

temperature of the test substance.

How a non-contact temperature meter works

According to the method of information output and its processing, devices for remote control of surface heating are divided into:

pyrometers;

thermal imagers.

Pyrometer device

Conventionally, the composition of these devices can be represented block by block:

an infrared sensor with an optical system and a mirror light guide;

an electronic circuit that converts the received signal;

a display that shows the temperature;

power button.

The flow of thermal radiation is focused by the optical system and directed by mirrors to the sensor for the primary conversion of thermal energy into an electrical signal with a voltage value directly proportional to infrared radiation.

The secondary conversion of the electrical signal occurs in the electronic device, after which the measuring and counting module outputs information to the display, usually in.

At first glance, it seems that for the user to measure the temperature of a remote object, it is enough:

turn on the device by pressing the button;

point to the object under study;

take readings.

However, for an accurate measurement, it is necessary not only to take into account the factors that affect the readings, but also to correctly select the distance to the object, which is determined by the optical resolution of the device.

Since these characteristics are directly proportional to each other, for accurate temperature measurement it is necessary not only to point the device correctly at the object, but also to select the distance to select the area of ​​the measured zone.

Then the optical system will process the heat flux from the desired surface without taking into account the influence of radiation from surrounding objects.

To this end, improved models of pyrometers are equipped with laser target indicators, which help to point the temperature sensor at the object and facilitate the determination of the area of ​​the controlled surface. They may have different principles of operation and have unequal pointing accuracy.

coaxial way is free from this shortcoming - the laser beam coincides with the optical axis of the device and accurately indicates the center of the measured area, but does not determine its boundaries.

An indication of the size of the controlled area is provided in the target designator with double laser beam. But at small distances to the object, an error is allowed due to the initial narrowing of the sensitivity area. This disadvantage is strongly manifested on lenses with a short focal length.

Target designators with cross-laser improve the accuracy of pyrometers equipped with short focus lenses.

Single circular laser beam allows you to determine the control zone, but it also has parallax and overestimates the readings of the device at short distances.

Circular precision laser pointer works most reliably and is devoid of all the shortcomings of previous designs.

Pyrometers display information about the temperature by text-numeric display, which can be supplemented with other information.

The device of thermal imagers

The design of these temperature measuring instruments resembles that of pyrometers. They have a hybrid microcircuit as a receiving element of the infrared radiation stream.

With its photosensitive epitaxial layer, it perceives the IR flux through a heavily doped substrate.

The device of the thermal imager receiver with a hybrid microcircuit is shown in the picture.

All methods of working with a thermal imager are performed in the same way as with a pyrometer, but on its screen a picture of electrical equipment is displayed, already presented in a revised color range, taking into account the state of heating of all parts.

When comparing the operation of a pyrometer and a thermal imager, you can see the difference:

the pyrometer determines the average temperature in the area it controls;

The thermal imager makes it possible to evaluate the heating of all the constituent elements located in the zone it observes.

Design features of non-contact temperature meters

The devices described above are mobile models that allow sequential temperature measurements at many places where electrical equipment works:

inputs of power and measuring transformers and switches;

contacts of disconnectors operating under load;

assembly of busbar systems and sections of high-voltage switchgear;

at the points of connection of wires of overhead power lines and other places of switching power circuits.

However, in some cases, performing technological operations on electrical equipment, complex designs of non-contact temperature meters are not needed and it is quite possible to get by with simple models installed permanently.

An example is a method for measuring the resistance of a generator rotor winding when working with a rectifier excitation circuit. Since large alternating voltage components are induced in it, its heating is constantly monitored.

Schemes operating on this principle are relatively simple and reliable.

Depending on the purpose, pyrometers and thermal imagers are divided into devices:

high-temperature, designed to measure very hot objects;

low-temperature, capable of controlling even the cooling of parts in frost.

The designs of modern pyrometers and thermal imagers can be equipped with communication systems and information transmission via remote computers.

The scope of use of devices for non-contact temperature measurement, the so-called pyrometers, is very large, they are used in railway transport, metallurgy, energy, housing and communal services, medicine, construction, scientific research, and energy saving. But we are especially interested in the construction industry, where there has long been a noticeable trend towards energy saving, reduction of heat losses of buildings and structures.

Pyrometers help to solve this problem - they are convenient to look for "cold bridges", areas with poor thermal insulation, gaps at the junctions of window and door blocks, to diagnose heating and ventilation systems using a non-contact method. Of course, there are much more convenient devices - thermal imagers, but they are clearly beyond the means of a “private trader”. But the pyrometer is inexpensive, and even though it does not work so clearly, it copes with its tasks.

The principle of operation of any pyrometer is based on measuring the thermal radiation power of the measurement object from any opaque surface, mainly in the infrared and visible light ranges. The IR-T1 has a high sighting ratio (10:1, in practice this means that at a distance of 10 m it measures the temperature in an area with a diameter of 1 m) and a wide range of measured temperatures, including the area of ​​negative values. With such indicators, its price looks very moderate.

Infrared pyrometer FLIR TG165 (non-contact thermometer)

The difference between pyrometers and thermal imagers is simple. The former are able to obtain only one temperature value per measurement, while the latter immediately produce an infrared image of an object with many measured values. But the fact is that a separate sensor is needed to measure the temperature of each point. How many points are measured - so many sensors should be (some electronic "tricks" that are sometimes equipped with thermal imagers do not fundamentally solve the problem).

And the price of any thermal imager depends most of all on the number of sensors assembled in a compact matrix. Even their cheapest models cost tens of thousands of rubles, and professional ones may well cost several hundred thousand. The thermal imager, even the simplest, is equipped with a full LCD screen, can store data in memory and connect to a computer for image transfer and analysis.

Among the temperature measurement methods, two main ones can be distinguished: temperature measurement by contact and non-contact methods. However, contact thermometers in many cases are too slow to measure temperature in real time, in addition, the measurement object can be located in a hard-to-reach place. The use of portable infrared pyrometers avoids these problems. Pyrometers provide instant, accurate measurements and are extremely easy to use. There is no contact with hot surfaces or moving objects. In fact, there is no better, inexpensive tool for diagnosing and identifying minor problems before they become serious.

The principle of operation of the pyrometer (non-contact thermometer) is to measure the strength of thermal radiation emanating from the object, mainly in the ranges of visible light and infrared radiation.

Since the range of both foreign and domestic devices offered is very large and, as a rule, adapted for specific purposes, when choosing, it should be clearly defined what type of pyrometer is needed for the planned measurements. Stationary pyrometers give very accurate results and are very rich in functionality, but they are not designed for on-the-fly and field measurements. Such pyrometers require calibration and adjustment, testing on black body models, and, despite the high reliability, accuracy and accuracy of measurements, as well as the convenience of presenting results, it is difficult to always have such a pyrometer at hand. In production conditions, compact portable thermometers come in handy, which allow you to instantly obtain temperature values, and at an acceptable level of accuracy. In addition, when choosing between a portable and stationary industrial pyrometer, the price plays an important role, which is much higher for industrial devices.

Consider the main technical characteristics of pyrometers which should be taken into account when choosing.

The first point is the temperature range, the value of which is planned to be controlled. Here, the area of ​​application and tasks for temperature measurement mainly play a role. If the need to use a pyrometer is limited, for example, to energy audits of premises and other measurements in ambient conditions, then the temperature range from -30 to +50 °C will be quite satisfactory. If the pyrometer is supposed to be used for temperature control in industrial facilities, pyrometers are already needed here that can work with temperatures that are several times higher than those indicated above. The cost of a pyrometer also depends on this parameter.

The second point worth paying attention to is the temperature resolution. In fact, this is the accuracy of the pyrometer readings, since this value characterizes the smallest temperature difference perceived by the pyrometer. Usually there are a number of secondary conditions that affect the accuracy of the results obtained, and the degree of their influence can be expressed from hundredths of a degree to several degrees.

Rice. 1. Pyrometer Pro "sKit MT-4003

Rice. 2.

At choosing a pyrometer it makes sense to study such a parameter as the sighting indicator. The price of the device largely depends on its size. The sighting index is the ratio of the diameter of the instrument control spot on the measurement object to the distance to the object and is denoted by D:S. The control spot is the minimum diameter of the radiating area required for temperature control. Thus, with a pyrometer with a higher sighting index, it is possible to measure the temperature of an object that is smaller in its geometric dimensions. For accurate temperature measurement, the dimensions of the object must exceed the size of the control spot of the device. For example, if the pyrometer has a sighting index of 1:100, this means that at a distance of 10 m the control spot will be only 10 cm, at a distance of 2.5 m - 2.5 cm.

Also a mandatory characteristic for all semiconductor devices is the operating temperature range. This parameter characterizes the temperature conditions in which the device can function normally and temperature changes will not affect the metrological properties of the device. When choosing a pyrometer taking into account this characteristic, one should take into account the possibility of calibrating the device, which provides for the possibility of compensating for thermal shock, as well as maintaining measurement accuracy over the entire range of operating temperatures with a sharp change in ambient temperature from subjectively warm to cold and vice versa.

In addition to all the above characteristics, it makes sense to pay attention to the conditions for displaying information. As a rule, any modern pyrometer is equipped with an LCD display, which displays the measurement data. For non-periodic measurements, this is usually sufficient.

As for the ergonomics of modern remote infrared thermometers, almost all of them have a convenient body shape and control. The most common body shape is the pistol. This version of the device is the most convenient for work.

For most models of pyrometers, the menu buttons and the display are located towards the user - this allows you to control it with just one finger. The trigger in these devices plays the role of the "start" button. When pressed, the surface is usually scanned, after releasing, the function of holding data on the display is triggered.

The table shows the technical characteristics of low-cost budget models of pyrometers from four manufacturers: Pro "sKit, AXIOMET, MASTECH and HIOKI of the same class. Of the features of the considered pyrometer models, the following can be noted: Pro" sKit MT-4003 pyrometer (Fig. 1) is not the most convenient to manage . All menu buttons are located on the side of the case. It will be difficult to control it with one hand. But since there are five buttons on the panel, and not three, like in HIOKI, the temperature unit can be changed without entering the menu. Another important difference between Pro "sKit MT-4003 and HIOKI and AXIOMET is the lack of a function to save the received measurements to memory.

Table

Technical characteristics of models of inexpensive budget pyrometers

Among all the pyrometers reviewed, the AXIOMET AX-7530 display (Fig. 2) displays, perhaps, the most parameters and settings at the same time. Thermal emissivity, current temperature, unit of measurement, laser sight indicator, battery indicator, plus one more line with menu options. At the bottom of the pyrometer handle there is a connector for connecting a K-type contact thermocouple. The MASTECH MS 6530 pyrometer (Fig. 3) is distinguished by its size. Compared to other models, it is more overall, the handle is much longer, and the display is much larger. MASTECH MS 6530 has the most modest functionality. This optical resolution index is the largest in the AXIOMET AX-7530 pyrometer (13:1), and the smallest in the HIOKI 3419-20 (Fig. 4) (8:1).

In terms of ergonomics, pyrometers AXIOMET AX-7530 and HIOKI 3419-20 are certainly in the lead. Pleasant body colors, comfortable shape and control speak in favor of these models.

After comparing infrared pyrometers of the same class, it can be seen that the most expensive pyrometer is inferior in terms of its technical performance to cheaper models. This can be explained by the class of the device. Still, he's Japanese! There are no complaints about its performance and functionality.

In this class of measuring instruments, it is difficult to trace the dependence of the cost on technical parameters. A noticeable difference is visible when comparing them with professional pyrometers, in which the optical resolution reaches 50:1, and the measurement range reaches 1250 ° C and there is the possibility of synchronization with a PC. But their price, respectively, is several times higher than the cost of budget models.

Surface temperature measurement is an important step in the organization of heat conservation of objects, repair work of electronic devices, construction work, various types of control. Often it is not possible to carry out this type of measurement with a contact-type thermometer due to the speed of the process, the inaccessibility of the measurement site, etc. Therefore, there is a need to use a device for measuring temperature by a non-contact method. Such a device is called a pyrometer.

Mass production of pyrometers began in the sixties of the last century. The first portable device was designed and manufactured for sale in 1967 by Wahl Corporation USA.

The name pyrometer comes from the Greek words heat and measure. This is a device capable of measuring body temperature in a non-contact way. The principle of operation is based on the analysis of the thermal radiation of the object.

When heated, any substance has the property of emitting light and heat rays. The higher the heating temperature, the stronger the radiation. One type of radiation is infrared. Since the brightness of the radiation is related to temperature, therefore, by determining the brightness, one can also measure the temperature.

Device classification

Devices are classified according to the following types:

Technical specifications

• optical resolution. This is an indicator characterized by the ratio of the area of ​​the capture area to the distance to the substance. This parameter depends on the type of device and can range from 2:1 to 600:1. The higher the score, the better. When used outside the professional sphere, this resolution is about 15:1.
• Operating range. It depends primarily on the characteristics of the sensors used in the device. Its value can lie in the range from minus 35 to plus 800 degrees.
• Accuracy. This value characterizes the boundaries of temperature change during measurements and depends on the correct calibration of the device. On average, the accuracy of pyrometers is 1.5%.
• Emissivity. This ratio of the power of an absolutely black object to the measured surface is usually taken to be about 0.95.

Regardless of the classification, pyrometers can also be supplied with various options. For example, the ability to connect to a personal computer, additional power supplies, remembering previous measurements, a clock, a laser pointer, a switch from Fahrenheit to Celsius, etc.

Detailed information about the use of an existing device can be obtained from its passport and instructions for use. Specify below general recommendations for using any type of device.

The measurement procedure itself should not cause difficulties. You just need to turn on the device, aim at the object to be measured, press the button (trigger) and read the value obtained on the screen.

Self-manufacturing

Schemes for pyrometers for measuring temperature by a non-contact method are complex, the installation is tight, calibration requires the presence of factory instruments. While the cost of finished devices in Chinese online stores is acceptable for anyone.

When purchasing an infrared pyrometer, you should make sure that there is an instruction manual available. The pyrometer is not a simple device, so it will be problematic to figure out the functions on your own. The instructions describe the essential points necessary for proper use. Here is an example of some of them:

• availability of outputs and type of software;
• error information;
• inertia coefficient;
• focusing capabilities;
• temperature gradient;
• working spectrum values;
• amount of radiation.

Although, in principle, its manufacture by one's own hands is possible. Understanding how the pyrometer works, you can assemble a brightness-type device. For this you will need:

1. photometric bulb;
2. ocular lens;
3. light filter;
4. battery;
5. rheostat;
6. milliammeter;
7. pipe.

A lens is installed at one end of the tube, which will serve as a lens. A light bulb is installed in the middle, and an eyepiece is installed at the other end. The light bulb is connected to the power supply through a rheostat and a milliammeter.

Measurements are carried out as follows. The telescope lens is directed to the object under study and the maximum image sharpness is achieved. After that, power is supplied from the battery and the filament is heated with a rheostat, corresponding to the brightness of the heated surface. Next, using the milliammeter, calculate the temperature. But for this, you first need to compile a reference table for the correspondence of temperature to milliammeter indicators.

Light filters serve to reduce the brightness of radiation at high temperature values, as well as to absorb the red part of the spectrum. The measurement accuracy of such a pyrometer will be low, although it is usually about ± 2%.

Summing up, we note that for measuring temperatures in hard-to-reach places it is better to use a non-contact pyrometer, infrared. A thermometer of this type is characterized by reliability, but it allows you to measure the temperature only at a single point. When measuring temperatures over large areas, a thermal imager should be used. Well-established manufacturers of pyrometers are: Testo, Optris and Raytek, and you should pay attention to them.

Pyrometers are devices for determining the temperature of an object by a non-contact method. A feature of the pyrometer is its low cost. To measure the temperature of an object, it is necessary to point the device at it, as a result, its temperature is determined.

Kinds

Pyrometers are classified according to certain criteria, and are divided into main types.

According to the basic principle of operation:

• Optical devices operating in the ranges of the visible light spectrum and infrared invisible rays.

1 - Lens
2 - Attenuating light filter
3 - Lamp
4 - Lamp filament
5 - Millivoltmeter
6 - Rheostat
7 - Rheostat engine
8 - Monochromatic light filter
9 - Eyepiece
10 - Ring handle of the rheostat
11 - Device handle

The principle of its operation is based on comparing the brightness of the object's radiation with the brightness of the thread, the radiation of which is known in advance. A beam of light from a heated object through the lens enters the device. Further along the eyepiece, the observer sees and compares the brightness of the object with the brightness of the temperature lamp filament.

Such a comparison is made in monochromatic light, which creates a special light filter. The thread is heated from the battery, its glow is regulated by a rheostat. The temperature is determined by the reading of the millivoltmeter of the pyrometer, which has a graduation in degrees according to the glow of the thread.

• radiometers(infrared), applying the radiation method for a limited range of infrared rays. Equipped with a laser pointer to ensure pointing accuracy.

1 - Lens
2 - Diaphragm
3 - Lamp
4 - Copper casing
5 - Housing
6 - Light filter
7 - Eyepiece
8 - Glow
9 - Millivoltmeter
10 - Glow

The principle of their operation is that the thermal radiation from a heated object is captured and focused by the sensitive element of the device, which is connected to a thermocouple. The device consists of a body with a lens. The sensitive part of the pyrometer is made in the form of a cruciform platinum plate, to which 4 thermocouple junctions are soldered, made in the form of a thermopile.

When the sensing element is cooled or heated, these thermocouples also heat up. The thermocouples and the platinum plate are in a glass tube enclosed in a copper casing, which has holes for heat rays passing to the sensing element. The ends of the thermocouples are led along the lamp base and connected to the terminals.

When pointing the pyrometer, it is necessary to ensure that the object is in the telescope and closes the field of view. Image clarity is achieved by moving the eyepiece. To protect the human eye from bright light, a light filter is used. It moves with a handle located near the terminals.

Optical devices also share:

• Tsvetovy e , multispectral, operating by comparing the brightness energy of an object with other regions of the spectrum. They apply to at least two study sites.
• Luminosity pyrometers. They are called devices with a disappearing thread. The work is based on comparing the radiation of the surface with the value of the radiation of the thread through which the electric current passes. The magnitude of the current strength is the value of the investigated temperature of the object.

According to the aiming method, pyrometers are divided into:

• with laser sight.
• With optical guidance.

By type of emissivity:

• WITH permanent coefficient.
• with variable coefficient.

Moving method:

• Portable(mobile) used in production areas where measurement mobility is required. Are intended for operation in severe climatic and industrial conditions. They have an increased optical resolution, which makes it possible to determine the thermal state of objects with a size of 5 mm. Portable devices are used in various industries to measure temperature and monitor complex technological processes that are associated with compliance with the temperature regime.

• Stationary pyrometers used in heavy industry. Serve for constant control over the production process in the foundry of metals, as well as the manufacture of plastic elements. They are mounted in hard-to-reach places where it is not possible to use temperature sensors from the point of view of the safety of workers.

Operating temperature:

• High temperature (more than +400 degrees). Used to measure highly heated objects.
• Low temperature (up to -30 degrees). Serve to study the temperature of bodies at negative values.

Device and work

Temperature can be measured by various devices, which are divided into contact models, and with a remote measurement method. Pyrometers are devices with a remote principle of operation.

Pyrometer standard version is made in the form of a pistol. It has a small liquid crystal display, which displays information about the measured temperature parameters.

Convenient housing and control panel, laser guidance and increased accuracy have made this tool popular among engineering and technical workers. The instrument display can be digital or analog. To ensure the required measurement accuracy, the diameter of the radiation surface is allowed not less than 15 mm

The functions of a pyrometer usually include:

• Visual and acoustic signal when a certain measurement limit is reached.
• Determination of the largest and smallest value among a series of measurements.
• Built-in memory for storing information.

Innovative models of pyrometers are equipped with a USB output for transferring information to an external drive or computer.

The job of a pyrometer is to identify heat waves emitted from a heated surface. The scheme of the device is shown below.

1 - Measured object
2 - Thermal radiation
3 - Optics
4 - Mirror
5 - Viewfinder
6 - Viewfinder axis
7 - Measuring and counting device
8 - Electronic converter
9 - Housing
10 - Button
11 - Sensor

Thermal radiation enters the pyrometer sensor through the socket. In the sensor, the heat energy is converted into an electric current signal. The power of this received signal is dependent on the temperature of the object under study. The higher the temperature, the greater the amount of current generated in the sensor.

Next, the signal is fed to the electronic converter, which supplies information to the LCD screen. One of the varieties of pyrometers are thermal imagers, which work on the principle of comparing the spectrum of heat radiation with a reference spectrum.

On a multi-color screen, a projection of the image appears from the effect of thermal radiation from objects that have fallen into the coverage area of ​​the device. Using the spectrum parameters, the temperature value is determined and its dynamic change on the surface of the material is clearly observed. Thermal imagers have become popular for monitoring residential heating functionality, as well as detecting leaks of coolant located in a hidden area.

Technical specifications

The functioning of pyrometers is accompanied by its own specific parameters, which are taken into account when choosing a device model, we will consider the main of these parameters in more detail.

Optical resolution

This parameter determines the area of ​​the object under study for temperature measurement, and depends on the viewing angle of the device lens, the larger the viewing angle, the larger the possible study area, taking into account the distance to the object.

The main condition for performing an accurate study is pointing the device precisely at the measured surface. If the capture area is larger, then the temperature will be determined with a large error. Optical resolution is the value of the ratio of the size (diameter) of the pyrometer capture to the distance to the object.

This parameter depends on the device model and varies widely: from 2:1 to 600:1. The higher resolution figure refers to professional pyrometers used to measure surface temperatures in industrial production. For domestic conditions, models of pyrometers with an optical resolution of 10: 1 are quite suitable.

Working range

The value of the operating range depends on the properties of the instrument's sensor. Most often, this parameter is in the range of -30 +360 degrees. For domestic needs, any type of pyrometers is quite suitable, since in the heating system the highest temperature of the coolant does not exceed 110 degrees.

Accuracy

This value shows the limits of temperature fluctuations during the measurement, and depends on the correct settings of the device. The average accuracy of pyrometers is 2%.

Emissivity

The ratio of the heat radiation power of the investigated surface to the radiation power of a completely black body is called the emissivity. Black, non-shiny objects have an emissivity of 0.95. Therefore, many remote temperature measuring devices are set to this value.

However, when trying to measure the temperature of an object made of aluminum and polished to a shine, the temperature value on the device screen will differ greatly from the actual temperature.

To ensure the necessary accuracy of temperature studies, most devices are equipped with a laser pointer, with which the spot of light is not in the center, but determines the optimal measurement boundary.

Terms of use

After purchasing the device, you should carefully study the attached instructions. The rules for using the device are simple. Improper use of the pyrometer will result in large measurement errors or malfunctions.

It is recommended to follow some rules when using this device.

• Turn on the device.
• Direct the socket to the surface to be examined.
• Use a laser pointer to determine the measurement limits.
• After bringing the device into operation, the temperature value will appear on the display. It depends on the design features of the device whether the data will be saved in the pyrometer memory or whether they will be replaced by the following data.

An ordinary person can easily cope with the practical use of a pyrometer. For companies that install and design autonomous heating systems, they have become a necessary device.

Scope of application

Pyrometers gained wide popularity in production with the presence of thermal power equipment: steam pipelines, heating mains, boilers, various heating devices.

Pyrometers are often used in the electric power industry to measure elements in switchboards. , cables and contact connections.

In the metallurgical industry, such devices measure the temperature of presses, machine tools, and furnaces. In the electronics industry, it is used to measure the level of heating of parts and circuit components.

Car enthusiasts use them to diagnose a car engine. Other areas of application of this useful device are: determination of heating, vehicle components, temperature during food storage.

When examining structures and residential buildings, the state of functioning of heating, air conditioning and ventilation, control of refrigeration equipment, pyrometers are indispensable assistants.

Most often, pyrometers are used in special cases, among which are:

• Operational temperature measurement.
• Study of objects with low heat capacity.
• Control of elements that are not allowed to be touched.
• Measurement of heating of a miniature object or its thin layer on the surface.
• Special control of the heating parameters of a certain mechanism due to the importance of the technological process.
• Control of the state of elements operating from electrical energy, which is often used in production.
• Monitoring the temperature of a moving object is especially effective with a pyrometer compared to other devices.
• Identification of heating in a hard-to-reach place or parts located at a considerable distance. The pyrometer will help diagnose the necessary parameters with the required accuracy and at a distance.
