YEJ-101 diaphragm pressure gauge
YEJ-101 diaphragm pressure gauge designed for measuring low positive and negative air pressure
Suitable for non-corrosive and non-explosive gas applications
Provides accurate and stable pressure measurement
Ideal for ventilation systems and boiler equipment
Reliable performance for industrial and commercial use
Application
This pressure gauge is suitable for measuring micro-pressure and negative pressure of neutral gases that do not corrode copper alloys and have no explosion risk.
Common applications include:
Boiler ventilation systems
Airflow monitoring equipment
Industrial gas pressure measurement
Description
The YEJ-101 diaphragm pressure gauge operates using a corrugated diaphragm capsule made of tin-phosphor bronze. When the measured gas enters the diaphragm through a connecting tube, it causes displacement at the free end of the diaphragm. This movement is transmitted through an internal mechanism, driving the pointer to indicate the corresponding pressure value on the dial.
Features
