Two color infrared pyrometer digital stove use

Two color infrared pyrometer digital stove use  1. The vault temperature of our hot blast stove is measured by the traditional method. The self-made platinum rhodium-platinum thermocouple or double platinum rhodium thermocouple is used to measure the temperature near the insulation wall and indirectly measure the temperature in the center of the furnace.Thermocouple temperature measurement is the most commonly used kiln temperature measurement method at present (hot blast furnace, sintering furnace, heating furnace, secondary combustion chamber, Krause furnace, etc.).Because the thermocouple works in the high temperature region between 1200℃ and 1300℃ for a long time, the service life of the thermocouple is very short. Usually, it needs to be replaced in about two quarters, with high cost and large maintenance. At the same time, because the top-burning hot blast stove is easy to form eddy current around the thermocouple, it is easy to damage the thermocouple.Ther…
