The WSSX series explosion-proof electric contact bimetallic thermometer shell is made of aluminum alloy, which separates the circuit inside the instrument that may generate sparks and arcs from the explosive gas mixture outside the case through the aluminum alloy shell, thus achieving the purpose of explosion-proof.
Explosion proof electric contact bimetallic thermometer with electrical contact device - mechanical electric contact. When the temperature of the measured medium changes, the thin shaft and steering transmission mechanism on the free end drive the pointer and moving contact to rotate, indicating the temperature change value on the dial. When it comes into contact or disconnects from the fixed contact (upper and lower limit fixed contact), the relays and contactors in the circuit system are activated to achieve automatic control and alarm.
The WSSX series explosion-proof electric contact bimetallic thermometer is a single needle indicating thermometer that uses a bimetallic strip wound into a spiral tube shape, with one end fixed and the other free end connected to a pointer. It rotates with temperature changes and drives the pointer to rotate to indicate temperature. It is the temperature measurement of liquid, steam, gas media, and solid surfaces within the range of -80 to+500 ℃ during the production of carbides and other explosives in the production sites of petroleum, coking, chemical, pharmaceutical and other enterprises.
