Diaphragm pressure gauge is also called micro pressure gauge. It is suitable for measuring low micro pressure of liquids, gases or vapors without explosion hazard, without crystallization, without solidification, and without corrosive effect on copper and copper alloys.
The bellows pressure gauge uses the bellows as a sensitive element for measuring tiny pressure. It is widely used in boiler ventilation, gas pipelines, combustion devices and other similar equipment to measure the micro-pressure and negative pressure of gas that does not corrode copper alloys and has no explosion hazard.

The stainless steel diaphragm pressure gauge is made of stainless steel according to the pressure guiding system and the casing. It is used in the measurement of micro-pressure and negative pressure of various gaseous media in technological processes with high corrosion resistance requirements.
The stainless steel diaphragm pressure gauge is a micro pressure gauge with corrosion resistance developed by referring to the structural characteristics of the original diaphragm pressure gauge. It is used in boiler ventilation and gas pipelines and other equipment to measure the micro-pressure and negative pressure of various gaseous media in technological processes with high corrosion resistance requirements. Accuracy class: 2.5

The instrument is composed of the measuring system (including joints, corrugated diaphragms, etc.), transmission mechanism (including pull rod mechanism, gear transmission mechanism), indicating parts (including pointer and dial) and shell (including case, ring and watch glass). composition. The working principle of the instrument is based on the corresponding elastic deformation of the free end of the corrugated bellows under the pressure of the medium to be measured, which is then driven and amplified by the gear transmission mechanism. The value is indicated on the dial. There is also a zero adjustment device, which can easily adjust the zero position.
The measuring 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 type bellows pressure gauge. If the pressure is -80Pa It is recommended to use a rectangular diaphragm pressure gauge.
