Description

Precision pressure gauges are mainly used to calibrate ordinary industrial pressure gauges, and can also accurately measure the pressure of non-corrosive, non-crystalline, non-solidifying media such as copper alloys and alloy structural steels at the process site.
The precision pressure gauge is equipped with a mirror ring (type A and type B) under the scale line, and the reading is clearer and more accurate during use. With zero adjustment device (B type)
The structure principle of precision pressure gauge:
It is composed of pressure measuring system, transmission mechanism, indicating device and shell. The pressure measuring elastic element is treated with a special process to make its performance stable and reliable. After being matched and debugged with a high-precision transmission mechanism, it can ensure accurate indication accuracy.
The working principle of the instrument is: when the pressure of the measured medium acts on the elastic element, it produces elastic deformation-displacement, and the transmission mechanism is amplified by the pull rod, and the measured pressure is indicated by the indicating device.
