The radiation pyrometer is designed and manufactured according to the functional relationship between the radiant energy of the object in the entire wavelength range and its temperature. The radiation temperature sensor is used as the primary instrument, and the electronic potentiometer is used as the secondary instrument. It belongs to the lens-focused infrared temperature sensor. The device has an aluminum alloy shell, the front is an objective lens, and a thermopile compensation diaphragm is installed in the shell. There is a baffle plate on the field of view diaphragm close to the thermopile. The function of the baffle plate is to adjust the radiation to the thermopile. The radiation energy of the product has a uniform graduation value. Eyepieces are installed on the detachable back cover to observe the image of the measured object.

The radiation pyrometer focuses the radiant energy of the measured object on the thermal element through a lens, and the thermal element converts the radiant energy into electrical parameters. The thermoelectricity is measured by the secondary meter from the known relationship between the thermoelectric potential and the temperature of the object Potential, showing the temperature value, this temperature value must be corrected by the total radiation black system number of the object or directly inserted into the high temperature salt bath furnace with a platinum rhodium 10-platinum thermocouple, with a DC potentiometer to measure the temperature, and then display the temperature with the meter Contrast, used to calibrate the accuracy of pyrometer to measure temperature.

The radiation pyrometer is a non-contact simple radiation temperature measuring instrument. It measures the surface temperature of the object according to the principle of the thermal radiation effect of the object. The radiation pyrometer is suitable for continuous measurement of various furnaces and high temperatures in the metallurgy, machinery, silicate and chemical industries. The temperature of cellars, salt baths, etc., and other places where thermocouples are not suitable for installation, with appropriate display instruments, can indicate, record and automatically adjust the measured temperature.
