Many of our enterprises encounter various pressure gauges during the production process. Now, let's briefly introduce the differences between membrane pressure gauges and other types of pressure gauges. The most important clarification is actually the membrane pressure gauge.

Diaphragm pressure gauge refers to the use of a diaphragm as a sensitive element for measuring small pressures, mainly used for measuring micro pressures. The measurement of micro pressure and negative pressure of gases that do not corrode copper alloys and have no explosive hazard is widely used in boiler ventilation, gas pipelines, combustion devices, and other similar equipment. Diaphragm pressure gauges are usually compared to spring tube pressure gauges, diaphragm pressure gauges, diaphragm pressure gauges, etc. 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.

The range of a capsule pressure gauge is different from that of a regular pressure measurement. Ordinary pressure gauges measure liquid media such as water and oil, or gas media such as oxygen and hydrogen, which cannot be oxidized in order to be measured by ordinary pressure gauges. However, we know that the media tested by bellows pressure gauges are all oxidizing media.

The safety factor of capsule pressure gauge is different from that of ordinary pressure measurement. Due to the low precision requirements for measuring with ordinary pressure gauges, and the fact that the pressure outside the measured medium does not change during measurement, the requirements for safety factors are relatively low in actual operation, and the hygiene conditions during measurement are not as strict. But the bellows pressure gauge measures some oxidizing media, which are exposed to air and will change at any time according to the contact with air, equivalent to the bellows pressure gauge measuring a variable. So the safety factor requirements for measuring the pressure gauge of the membrane box are very strict, and the hygiene conditions during measurement are also very demanding.
