WSSX-3/4/5 series bimetallic electric contact thermometerDetailed product description：

Double metal electric contact thermometer WSSX-3/4/5 series

The bimetallic electric contact thermometer is equipped with an electrical contact device, namely a 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 with the temperature change. At the moment of contact or disconnection with the fixed contact, the relays and contactors in the circuit system are activated to achieve automatic control and alarm purposes. It can measure the temperature of liquid, vapor, and gas media within the range of -80 ℃ to 500 ℃.
