WSSX series electric contact bimetallic thermometer has electric contact device, a mechanical electric contact. When medium temperature changes, fine axis and steering transmission mechanism on the free end turns pointer and the moving contact, the dial indicates change of temperature, at the time of contact or cut off with the fixed contact (upper and lower limit contact), it makes the circuit system relay and contactor act, then realize automatic control and alarm, it’s in accordance with JB/T8803 1998 standard.
