◎Application Description

This gauge is suited for measuring the pressure of all kinds of liquid with some corrosion, nonsolidified or non-crystallized.

The material of diaphragm can be selected when the corrosion of the service medium is concerned. Outer case is made of stainless steel, and can be used in corrosive environment.


This gauge is made up of the measuring system (involve connector, flange and diaphragm), gear setting, point setting and outer case.

When the service medium pressure act on the flexibility parts (diaphragm), and make it move, with the stick help, sending and making it bigger, then the pointer point it out on the dial.
