Electric-contact BimetalThermometer

Brief Description  

The WSSX-312 electric contact bimetal thermometer isused to measure field middle and low temperature, can be used to measuredirectly the temperature of liquid and gas. Compared with glass mercury thermometer,it has no mercury harm, easy to read, strong and durable. The protection tube,joint and locking bolt of WSSX series bimetallic thermometer are 1cr18ni9tistainless steel, the case is made of stretched aluminum board after machining,surface is dealt with electrophoresis processing, the head (cover and box) isring type double rubber ring seal locking structure, thus the waterproof &anti-corrosion performance is good, radial (straight) type adopts bend tubestructure, novel appearance, light, beautiful and unique.  

Working principle

WSSX serieselectric contact bimetallic thermometer has electric contact device, amechanical electric contact. When medium temperature changes, fine axis andsteering transmission mechanism on the free end turns pointer and the movingcontact, the dial indicates change of temperature, at the time of contact orcut off with the fixed contact (upper and lower limit contact), it makes thecircuit system relay and contactor act, then realize automatic control andalarm, it’s in accordance with JB/T8803 1998 standard.
