Electric contact pressure gauges are widely used in petroleum, chemical, metallurgy, electric power, machinery and other industries or in electromechanical equipment to measure the pressure of various fluid media without danger of explosion.

The instrument can realize automatic control and signaling (alarm) of the pressure system under test (control) by using it with related electrical equipment (such as relays, frequency converters, etc.).

The current of the electric contact pressure gauge should not exceed 3a (ampere), otherwise it will cause an accident.

The pressure gauge should be perpendicular to the equipment, and bumps and vibrations should be prevented during transmission and operation of the equipment.

Electric contact pressure gauge is suitable for seismic pressure gauge models with ambient temperature of -40 ℃~+70 ℃, humidity not greater than 85%, and vibration or violent pulsation of the measured medium, which has no effect on reliable contact and accurate reading, etc. occasion.

The electrical circuit of the electric contact pressure gauge is carefully checked after setting the price list and wiring of the electric contact pressure gauge, and the test run is carried out.

When adjusting a given voltage value, the contactor must be tightened with a slotted screw.

When measuring static load, the contact pressure gauge can use 3/4 of the upper limit of measurement, when measuring the alternating load of the pressure gauge manufacturer, it can use 2/3 of the upper limit of measurement, and the upper limit of measurement can be used for instant measurement.

When measuring medium with high viscosity and severe swing pressure, isolation device and buffer device should be added.

The pressure gauge should be checked frequently (every three months)

Electric contact pressure gauges should always be kept clean and properly maintained during use.

Under normal circumstances, the instrument can be used with corresponding electrical equipment (such as relays, contactors, etc.) (contact types include upper and lower limit type, double upper limit type, double lower limit type, etc.), which can automatically control the pressure system under test (control). Control and signaling (alarm).

Wetted materials are copper or stainless steel, etc., the user can choose according to the actual use. Suitable for pressure measurement in petroleum, chemical, metallurgy, food and other industries.
