Product details
1. The explosion-proof thermal resistance is usually used together with the display instrument and recording instrument. Directly measure the surface temperature of liquid, steam, gas medium and solid in the range of 0-500 ℃ with hydrocarbon explosion in the production site.




Features of explosion-proof thermal resistance: spring type temperature sensing element, good anti vibration performance; high measurement accuracy; high mechanical strength, good withstand voltage performance; imported film resistance element, reliable and stable performance;




Working principle of explosion-proof thermistor:




The explosion-proof thermistor uses the principle of gap explosion-proof to design the junction box and other components with sufficient strength to seal all the components that will produce sparks, arcs and dangerous temperatures in the junction box cavity. When the cavity explodes, it can extinguish and cool through the gap between the joint surfaces, so that the flame and temperature after explosion cannot be transmitted outside the cavity, so as to measure the temperature.




The industrial flame-proof thermocouple is a kind of temperature sensor, which is widely used in the automatic control system of chemical industry. Through the temperature sensor, the temperature parameters of the controlled object can be changed into electrical signals, which can be transmitted to the display, recording and regulating instrument to detect, regulate and control the system. In the chemical plant, the production site is often accompanied by a variety of flammable, explosive and other chemical gases, steam, if the use of ordinary thermocouples is very unsafe, it is very easy to cause environmental gas explosion. Therefore, the flame-proof thermocouple must be used as the temperature sensor in these occasions. The flame-proof thermocouple products produced by our company are suitable for the places with explosive gas risk in the temperature range of D Ⅱ CT6.
