Precision pressure gauges are mainly used to verify ordinary industrial pressure gauges. Precision pressure gauges can also accurately measure the pressure of non corrosive, amorphous, and non solidified media such as copper alloys and alloy structural steel on the process site.
The precision pressure gauge is equipped with a mirror ring (Type A and Type B) 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 an outer shell. The pressure measuring elastic element of the precision pressure gauge has been specially processed to ensure stable and reliable performance. After being matched with a high-precision transmission mechanism for debugging, 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 causes 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:
The environmental conditions for the use of precision pressure gauges are 5-40 ℃, with a relative humidity not exceeding 80%, and the environmental vibration and pressure source fluctuations have no impact on the accurate reading of the instrument.
Temperature influence 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)
