Electric Contact Pressure Gauge with Adjustable Pressure Limit Control 100mm Dial Size and 1.6 MPa Scale

The electric contact pressure gauge is a multifunctional industrial instrument that integrates pressure measurement, automatic pressure regulation, and overpressure alarm functions.

Unlike ordinary pressure gauges that only display pressure values, this gauge features adjustable electrical contact points. Users can set upper and lower pressure thresholds via the central red knob. When system pressure reaches preset values, internal contacts switch on/off to trigger alarms, start or stop water pumps, air compressors, and supporting equipment automatically.

Widely used in boiler rooms, water supply systems, fire protection equipment, pneumatic and hydraulic automation projects.
