Explosion proof multi wavelength pyrometer

Explosion proof multi wavelength pyrometer  Why do we choose infrared pyrometer to measure temperature change in industrial process? Compared to thermocouple thermometry， what is the advantage of fixed pyrometer, especially 2-color infrared pyrometer?  Disadvantage of thermocouple thermomery: 1. Infrared thermometer accuracy: Thermocouple thermometry is the most traditionally method to detect temperature in furnaces (hot blast furnace, sintering furnace, heating furnace, secondary combustion chamber, Klaus furnace, etc.) . This method measures central temperature in furnace indirectly by measuring the temperature near insulation wall with fabricated platinum rhodium-platinum thermocouple or double platinum rhodium thermocouple. 2. Harsh environment influence amplification: Conditions in furnace are always tough alone with high temperature and high pressure. Limited to the requirements of operation environment and instrument’s structure, thermoc…
