Ordinary pressure gauge

The ordinary pressure gauge belongs to the local indication type pressure gauge, and the pressure is displayed on the spot without the remote transmission display and adjustment function.

In the process of industrial process control and technical measurement, the general pressure gauge is more and more widely used due to the high mechanical strength of the general pressure gauge and the convenience of production and convenient reading.

Uses General pressure gauges are suitable for measuring the pressure and vacuum of liquids, gases or vapors that are non-explosive, non-crystalline, non-solidifying, non-corrosive to copper and copper alloys.

principle

The ordinary pressure gauge transmits the pressure deformation to the pointer through the elastic deformation of the sensitive component in the watch, the Bourdon tube, and then through the conversion mechanism of the movement inside the watch, causing the pointer to rotate to display the pressure.

Precautions for use 1) The working pressure should be 1/3 to 2/3 of the full scale, and the maximum range of use should not exceed 3/4 of the full scale.

2) The verification period is generally not more than half a year. The medium of the pressure measurement part has large fluctuations, frequent use, high accuracy requirements, and strict requirements on safety factors. The verification period can be shortened according to the specific situation.

3) The working environment should be free of corrosive gases. 'Ordinary pressure gauge
