Seismic pressure gauge is suitable for the severe vibration environment, can tolerate the pulsation of the medium, the impact and sudden unloading, clear indication stability Widely used in mechanical oil chemical metallurgy mine electric power departments, measurement of copper and copper alloy non-corrosive medium pressure Product has a good seismic performance, particularly applicable to mechanical vibration and medium pulse work environment Seismic pressure gauge can be measured without explosion danger Without the crystals solidify and corrode the copper alloy liquid gas media such as steam pressure

Vibration proof pressure gauge form：

1、The absolute pressure, the total pressure acting on the surface area of the vessel by the lateral medium, is called the pressure. It is indicated by the sign pi. An instrument used to measure absolute pressure is called an absolute pressure meter.

2、Atmospheric pressure, the pressure formed by the weight of the air column on the earth's surface, is called atmospheric pressure. It varies with latitude, altitude, and weather conditions. The values are measured by barometers and expressed in symbolic pd.

3、Table pressure, usually a pressure measuring instrument, is in the atmosphere, and the measured pressure is equal to the difference between absolute pressure and atmospheric pressure. This is called table pressure, expressed in symbolic pb.

4、When the absolute pressure is less than the atmospheric pressure, the pressure of the table is negative, and the absolute value is called the vacuum degree. It is expressed by the symbol pz. 5, differential pressure, the difference between the two parts of the equipment is referred to as differential pressure. In the production process, the differential pressure is used as the process parameter directly, and the differential pressure measurement can also be used as an indirect means of flow measurement and level measurement.
