Application
The bellows pressure gauge uses a bellows as a sensing element for measuring minute pressure. The micro-pressure and negative jade which are not corrosive to copper alloy and have no explosive danger, are widely used in boiler ventilation, gas pipeline combustion devices and other similar equipment.
All stainless steel bellows pressure gauges are made of stainless steel according to the pressure guiding system and the outer casing. It is applied to the measurement of micro pressure and negative pressure of various gaseous media in processes with high corrosion resistance requirements.
Principle
The meter consists of a measuring system (including joints, corrugated bellows, etc.), transmission mechanism (including the pull rod mechanism, gear transmission mechanism), indicating parts (including the pointer and dial) and the outer casing (including the table light, the village circle and the watch glass). composition. The working principle of the instrument is based on the pressure of the corrugated diaphragm box under the pressure of the measured medium, and the corresponding elastic deformation is generated and then amplified by the gear transmission mechanism. The pointer fixed on the gear shaft will be measured at the dial. Indicated on it. In addition, the instrument has a zero adjustment device, which can easily adjust the zero position.
