Explosion proof industrial thermal resistance or thermal resistance of the security is a temperature sensor, in the chemical industry wide application of automatic control system, through the temperature sensor, can control the temperature of the object parameters into electrical signals, passed to the display, record and adjust the instruments, the implementation of system testing, regulation and control. In the chemical plant, production site often accompanied by a variety of flammable, explosive and other chemical gases, steam, if ordinary platinum resistance is very insecure, vulnerable to the environment caused by gas explosion.
Features:
1. Have a compression spring-type temperature sensing element, anti-vibration performance
2. Measurement precision
3. Without compensation wire, cost savings
4. Imported film resistive element, stable and reliable performance
