Manufacturer of photoelectric thermocouplesThe photoelectric thermocouple is based on the blackbody radiation theory and adopts a temperature measurement method that combines contact and non-contact methods. During the temperature measurement process, slowly insert the blind end of the sight tube into the measured temperature medium. When the blind end temperature measurement hole of the temperature tube reaches the specified depth and reaches thermal equilibrium with the measured medium, fix the sight tube clamp on the furnace wall and seal the gap between the sight tube and the kiln wall with asbestos rope or ceramic wool. To prevent fireworks from erupting from the kiln. Then connect the signal line (red for positive pole) to the input terminal of the secondary instrument. When the thermal radiation intensity on the inner surface of the photoelectric thermocouple thermometer tube matches Boltzmann's law, it can be used to measure the actual temperature inside various high-temperature furnaces and molten liquids, without being affected by environmental pollution and target blackness coefficient.
