The pressure gauge is used to measure the pressure of non-corrosive, non-crystallize, non-solidify, and non-precipitation, liquid, gas or steam

The measuring system is composed of the joint and spring. As the measured pressure changing, free end of spring tube is shift which drive fan wheel gear rotating rod to indicate the pressure value on the scale board. In order to eliminate the gap between fan wheel and shaft gear, we install plate-shaped springs on the shaft gear.
