Explosion-proof Electric contact Temperature Gauge

Electric contact Temperature gauge is widely used in petroleum, chemical, metallurgical, power plants and other industrial departments or service mechanical and electrical equipment for measuring the temperature of various medium. Usually the electric contact temperature gauge is connected to some electrical devices such as relay, AC contactor, etc. to implement automatic control and alarm.

Product Description

When the temperature reading pointer reach to the setting limit, it will trigger the electrical contact action to open or close the circuit to control the other equipment stopping or running.


Electric parameter and control type:

Contact rate Power supply Max. working
Control type
30VA DC: 24V
AC: 220V or 380V
1A Lower-limit and Upper limit
Double Lower-limit and Double Upper-limit
1.    When the working current is 1 A, the working voltage must be lower than 40V
2.    Please confirm the power supply (either DC or AC) and control type( either Lower-limit / Upper limit or Double Lower-limit / Double Upper-limit.
3.    The electrical contact is normal open, when the temperature reach to the setting limit temperature, the electrical contact will close.
4.    If the marked power supply on gauge dial is 380VAC, user can use 220VAC or 380VAC.
