Differential Pressure Gauge Structure
What is the structure of differential pressure gauge? Let's find out interesting information about this device with VCR. VCR - specializing in cleanroom equipment for contractors in Vietnam.
1. Differential pressure gauge structure
A differential pressure gauge is comprised of:
+ Sensing element
+ Drive bar
+ Magnet
+ Pointer
+ High-pressure connection
+ Low-pressure connection
+ Bezel with magnets
2. Differential pressure gauge operation principles
When the pressure at HP port (Arrow 1) is higher than the pressure at LP port (Arrow 2), the rubber will move in the direction of Arrow 3, pass the drive bar. The magnet will go in the direction of Arrow 4. Through bezel with magnets, clockwise will rotate in Arrow 6 direction.
Note:
The pressure of cleanroom is low, from 10 - 15 Pa, so the sensing element and the clockwise are very sensitive
The gauge will have the exact value when it is mounted vertically
After installation, if the clockwise are not at 0 Pa, you could fix it by Zero reset screw
