(Summary description)Electric contact pressure gauges are widely used in industries such as petroleum, chemical, metallurgical, electrical, mechanical, and electromechanical equipment, to measure pressures of various fluid media without explosion hazards.
This instrument can be used in conjunction with relevant electrical equipment (such as relays, frequency converters, etc.) to achieve automatic control and signaling (alarm) of the tested (controlled) pressure system.
The current of the electric contact pressure gauge should not exceed 3a (amperes), otherwise it may cause an accident.
The pressure gauge should be perpendicular to the equipment, and collision and vibration should be prevented during transmission and equipment operation.
The electric contact pressure gauge is suitable for seismic resistant pressure gauge models with ambient temperatures ranging from -40 ℃ to+70 ℃, humidity not exceeding 85%, and vibration or severe pulsation of the measured medium, which does not affect reliable contact and accurate reading.
The electrical circuit of the electric contact pressure gauge should be carefully checked and tested after being installed in the price list and wiring of the electric contact pressure gauge.
When adjusting the given voltage value, the contactor must use a single slot screw tightening tool.
When measuring static load, the contact pressure gauge can use 3/4 of the upper measurement limit. When measuring the alternating load of the pressure gauge manufacturer, 2/3 of the upper measurement limit can be used. In an instant, the upper measurement limit value can be used.
When measuring media with high viscosity and severe shaking pressure, isolation and buffering devices should be added.
Pressure gauges should be regularly calibrated (every three months)
Electric contact pressure gauges should be kept clean and properly maintained during use.
In general, instruments can be used in conjunction with corresponding electrical equipment (such as relays, contactors, etc.) (with contact types such as upper and lower limit, double upper limit, and double lower limit) to achieve automatic control and signaling (alarm) of the pressure system being tested (controlled).
The liquid receiving materials include copper or stainless steel, and users can choose according to their actual usage situation. Suitable for pressure measurement in industries such as petroleum, chemical, metallurgy, and food.
