Product Description:
Precision pressure gauges are mainly used to calibrate ordinary industrial pressure gauges. Precision pressure gauges can also accurately measure the pressure of non corrosive, non crystalline, and non solidifying media on materials such as copper alloys and alloy structural steels at the process site.
The precision pressure gauge is equipped with a mirror ring (A-type B-type) below the scale line, which provides clearer and more accurate readings during use.
Structural principle:
A precision pressure gauge consists of a pressure measuring system, a transmission mechanism, an indicator device, and a housing. The pressure measuring elastic element of the precision pressure gauge is treated with special technology to ensure stable and reliable performance of the precision pressure gauge. After being matched and debugged with a high-precision transmission mechanism, it can ensure accurate indication accuracy.
The working principle of a precision pressure gauge is that when the pressure of the measured medium acts on the elastic element, it produces elastic deformation displacement, which is amplified by the transmission mechanism driven by the pull rod, and the measured pressure is indicated by the indicator device.
Main technical indicators:
Measurement range, accuracy level and characteristics of precision pressure gauge
The environmental conditions for the use of precision pressure gauges are: 5-40 ℃, relative humidity not exceeding 80%, and environmental vibration and pressure source fluctuations have no effect on the accurate reading of the instrument.
Temperature effect of precision pressure gauge: If the ambient temperature deviates from 20 ± 3 ℃ (Type A) or 20 ± 2 ℃ (Type B), an additional temperature error of 0.4%/10 ℃ must be considered
Precision pressure gauge weight: 1kg (Type A) 1.4kg (Type B)
