WSSXB Explosion-proof electric contact bimetallic thermometer
Application and Features:
WSSXB series explosion-proof electric contact bimetallic thermometer outside are made of aluminum alloy, the aluminum shell can separate the spark generated inside of instrument from the explosive gas mixture outside, to achieve explosion-proof purpose.
Explosion-proof electric contact bimetal thermometer is with electric contact device, quillshaft of the free end drive pointer and movable contact, and indicate the temperature change on the dial when the medium temperature changes, when it contact with or break from the constant contact, it will make relay and contact action, to achieve auto control and alarm purpose.
Explosion-proof electric contact bimetal thermometer is one kind of single pointer thermometer which is made of spiral tube dual metal strip end are fixed, another free end are connect with pointer, it rotate when temperature changing, and drive pointer rotate to indicate the temperature. It is suitable to be used for measuring liquid, steam, gas or solid temperature in petroleum, coking, chemical, medicine field, when the working place is with explosive gas and the temperature range -80~600 degree.
