Xi'an Automation Instrument No.1 Factory
◎Application description
Precision pressure gauge is mainly used for checking industrial general PG and accurately measuring the pressure of all kinds of medium which noncorrosive, noncrystalline and non-condensing for copper alloys or steel alloys.
The gauge has a mirror ring under the scale (A type and B type)t o read more clearly and more accurately. And has zero adjustable setting (B type).
◎Structure
This gauge is made up of measuring system, gear setting, pointing setting and outer case. The flexibility part is dealt with the special techniques to make the operation reliable. With the use of the high accurate gear setting,it can assure the high accuracy.
The principle of precision pressure gauge: The medium pressure acts on the flexibility part and make it move, with the help of connecting rod, magnified by the gear setting, and point it out on the dial.
