Diaphragm Pressure Gauge adopts diaphragm as the sensitive component for testing tiny pressure. It can measure the tiny and negative pressure of gas with no corrosion to copper alloy and no explosion danger which is widely used in stove ventilation, gas pipes, burning equipment and other similar devices.


Structure Principle
The gauge is consisted of measuring system(including connector and diaphragm etc.), transmission gear, indicator device and outer casing. When the pressure of media effects on the diaphragm, the free end will emerge elastic deformation—displacement.  After the driving of driving rod and the amplifying of transmission gear, the measured pressure will be indicated on the plate of the meter by the indicator device.

Working Situation and circumstance: The meter should be installed vertically in the circumstance of working temperature -25~55℃, relative humidity less than 80% and the air without corrosive and harmful gas.
Temperature Impact: When the working temperature deviates 20±5℃, the temperature additional error is less than 0.4%/10℃
