General pressure gauge belonging to the local indication type pressure gauge, display the size of the pressure, without remote transmission and display, regulating function. In industrial process control and measurement technology in the process, due to the General Pressure Gauge of the elastic sensitive element with very high mechanical strength and convenient production, installation is simple and convenient reading and other characteristics, the general pressure gauges are used more and more widely.

General pressure gauges are used for measuring no explosion, no crystallization, solidification, the copper and copper alloy no corrosive effect of the liquid, gas or steam pressure and vacuum.

The general pressure gauge's working principle is the pressure gauge through the table within the sensitive element of the Bourdon tube elastic deformation, the table movement conversion mechanism of the elastic deformation of the Bourdon tube is converted to rotary motion, to display the pressure caused by the deflection of the needle.

Use of General pressure gauge need to pay attention to the following points:

1) working pressure using the full range of 1 / 3 to 2 / 3 is appropriate, use shall not exceed a maximum of full scale 3 / 4.

2) verification cycle is generally not more than half a year, pressure parts of medium large fluctuations, the frequent use, accuracy requirements are higher, and the factor of safety requirements more stringent, according to specific situation will be appropriate to shorten the test cycle.

3) the working environment should be no corrosive gas.
