Stainless steel shock resistant micro pressure diaphragm pressure gauge

overview：　

The membrane box pressure gauge uses a membrane box as a sensitive element for measuring small pressures. The measurement of micro pressure and negative pressure that does not corrode copper alloys and does not contain hazardous gases is widely used in boiler ventilation, gas pipelines, combustion devices, and other similar equipment.

The stainless steel diaphragm pressure gauge is made of stainless steel material according to the pressure system and housing. Applied to the measurement of micro pressure and negative pressure of various gas media in processes with high corrosion resistance requirements.

The stainless steel diaphragm pressure gauge is a micro pressure gauge with corrosion resistance developed based on the structural characteristics of the original diaphragm pressure gauge. Applied to equipment such as boiler ventilation and gas pipelines, measuring the micro pressure and negative pressure of various gas media in processes with high corrosion resistance requirements.

Structural principle:

The instrument is composed of a measuring system(Including joints, corrugated film boxes, etc)Transmission mechanism(Including pulling rod mechanism, gear transmission mechanism), indicating components(Including pointers and dials)And the shell(Including case, dial and glass)Composed of. The working principle of the instrument is based on the elastic deformation of the free end of the corrugated film box under the pressure of the measured medium, which is then amplified by the gear transmission mechanism. The measured value is gradually indicated on the dial by the pointer fixed on the gear shaft. There is also a zero adjustment device that can easily adjust the zero position.

The measurement range of the bellows pressure gauge is -80~60000Pa, but different bellows pressure gauges should be selected according to different pressure ranges. When the pressure is between -1000Pa~60000Pa, it is recommended to use a disc bellows pressure gauge. If the pressure is between -80Pa, it is recommended to use a rectangular bellows pressure gauge.
