Explosion-Proof Electric Contact Temperature Gauge/temperature control

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.

Electric parameter and control type:

Contact rate
Power supply
Max. working
current
Control type
30VA
DC: 24V
AC: 220V or 380V
1A
Lower-limit and Upper limit
Double Lower-limit and Double Upper-limit
Note:
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.
