Description
The bellows pressure gauge uses a bellows as a sensitive element to measure tiny pressure. It is used to measure the micro pressure and negative pressure of gases that are not corrosive to copper alloys and have no explosion hazard. It is widely used in boiler ventilation, gas pipelines, combustion devices and other similar equipment.
Principle of bellows pressure gauge:
The instrument consists of a measuring system (including a joint diaphragm, etc.), a transmission mechanism, an indicating device and a housing.
When the pressure of the measured medium acts on the bellows, its free end produces corresponding elastic deformation and displacement, which is driven by the lever to drive the transmission mechanism to enlarge, and the measured pressure is indicated on the instrument panel by the indicating device
