Liquid Filled Capsule Pressure Gauge
The capsule pressure gauge is also named micro-pressure gauge. It is widely to measure non-explosion, non-crystallizable, non-concretion liquid, gas and stream which is not corrosive to copper and copper alloy. It can be used in boiler draft, gas pipeline, combustion apparatus and other similar facilities.
This capsule pressure gauge is composed with measure system (including connector, bellow, etc), transmission mechanism (including pull-rod mechanism and gear drive), indicating device (including pointer and dial) and shell (including case, lining ring and glass). https://www.hongqiinstrument.com/pressure-gauge/general-pressure-gauge/liquid-filled-capsule-pressure-gauge.html
