Information

The aluminum pyrometer manufacturers believe that the temperature scale of the color temperature is determined by the brightness temperature of the two-color pyrometer, so the measurement accuracy of the colorimetric pyrometer is worse than that of the photoelectric pyrometer; The application in is still relatively extensive.

aluminum pyrometer china

Aluminum pyrometer manufacturers say that radiation pyrometers are of two types: refraction and reflection. A pyrometer made according to the Stefan-Boltzmann law of thermal radiation. The temperature measurement range and performance of radiation pyrometers are the same as those of optical pyrometers.
The measurement error of radiation pyrometer mainly comes from:
① The selective absorption of the intermediate medium (such as the atmosphere, etc.) makes the infrared part of the radiant energy reaching the receiver lose more;
② The distance from the heat source to the pyrometer is not measured (usually, each radiation pyrometer specifies a ratio between the diameter of the observed surface area and the distance between the pyrometer lenses);
③ The selective absorption characteristics of the receivers in various pyrometers are different, which causes the spectral emissivity to deviate from the selected value;

④ The temperature changes of the hot and cold ends of the thermopile, the error of the instrument, etc.

Measuring range of optical pyrometers

When the temperature to be measured is higher than the range that thermocouples can use, and where it is impossible or not suitable for installation of thermocouples, optical pyrometers can generally meet this requirement.
