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

Introduction
Explosion-proof type Electrical contact pressure gauge is widely used in petroleum, chemical, metallurgical, power plants and other industrial departments or service mechanical and electrical equipment for measuring the pressure of various medium. Usually the electric contact pressure gauge is connected to some electrical devices such as relay, intermediate relay, AC contactor, etc. to implement automatic control and alarm.
Principle of Explosion-proof type Electrical contact pressure gauge
When the pressure 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.

| Nota:
1. Please confirm the power supply (either DC or AC) before ordering. 2. When the measured pressure increase to the high limit, the electrical contact of high limit will close. 3. If the marked power supply on gauge dial is 380VAC, user can use 220VAC or 380VAC. 4. Electrical contact only output switch signal for connecting the external relays (such as intermediate relay, AC contactor ) |
