Structural principle of capsule pressure gauge

Capsule pressure gauge is also called micro pressure gauge. It is suitable for measuring the low micro pressure of liquid, gas or steam without explosion hazard, crystallization, solidification and corrosion to copper and copper alloy.

Introduction:

The capsule pressure gauge uses the capsule as the sensitive element for measuring micro pressure. It is widely used in boiler ventilation, gas pipeline, combustion device and other similar equipment.

The stainless steel capsule pressure gauge is made of stainless steel according to the pressure guiding system and shell. It is used to measure the micro pressure and negative pressure of various gas media in the process with high corrosion resistance requirements.

Stainless steel capsule pressure gauge is a micro pressure gauge with corrosion resistance developed with reference to the structural characteristics of the original capsule pressure gauge. It is applied to boiler ventilation, gas pipeline and other equipment to measure the micro pressure and negative pressure of various gas media in the process flow with high corrosion resistance requirements. Accuracy class: 2.5

Structure principle:

The instrument is composed of measuring system (including joint, corrugated film box, etc.), transmission mechanism (including pull rod mechanism and gear transmission mechanism), indicating components (including pointer and dial) and shell (including watch case, lining ring and watch glass). The working principle of the instrument is based on the corresponding elastic deformation of the free end of the bellows under the pressure of the measured medium, which is transmitted and amplified by the gear transmission mechanism, and the measured value is indicated on the dial one by one by the pointer fixed on the gear shaft. There is also a zero adjustment device, which can easily adjust the zero position.

The measuring range of capsule pressure gauge is - 80 ~ 60000pa, but different capsule pressure gauges shall be selected according to different pressure ranges. Disc capsule pressure gauge is recommended when the pressure is - 1000Pa ~ 60000pa, and rectangular capsule pressure gauge is recommended when the pressure is - 80pa.
