WSSX-410B WSSX-480B WSSX-412B WSSX-482B Electric contact bimetallic thermometer

WSSX-410B WSSX-480B WSSX-412B WSSX-482B Explosion proof bimetallic thermometer

Working Principle of WSSX-410B WSSX-480B WSSX-412B WSSX-482B Explosion proof bimetallic thermometer

WSSX-410B WSSX-480B WSSX-412B WSSX-482B Explosion proof bimetallic thermometer will twist because of different expansion factor of active layer and passive layer of bimetal. Then thermal energy turns to mechanical energy, which will drive pointer revolve so that temperature of measured medium will be displayed. The spark is inside to avoid leakage to the outside. is made up of spiral bimetal temperature sensing components. Bimetal expands when heated.
