Description

The precision pressure gauge is mainly used to verify the industrial ordinary pressure gauge. The precision pressure gauge can also accurately measure the pressure of non corrosive, non crystalline and non solidified media such as copper alloy 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 can read more clearly and accurately in use, and is equipped with a zero adjustment device (type b)

■ structural principle:

The precision pressure gauge is composed of pressure measuring system, transmission mechanism, indicating device and shell. The pressure measuring elastic element of the precision pressure gauge is treated by special process, so that the performance of the precision pressure gauge is stable and reliable. After matching and debugging with the high-precision transmission mechanism, it can ensure the accurate indication accuracy.

The working principle of the precision pressure gauge is: when the pressure of the measured medium acts on the elastic element, it will produce elastic deformation displacement, which will be amplified by the driving mechanism driven by the pull rod, and the measured pressure will be indicated by the indicating device.

■ main technical indicators:

○ measuring range, accuracy grade and characteristics of precision pressure gauge

Model spring tube material measurement range MPa accuracy grade structural features YB-150A Tin Phosphorus Bronze chromium vanadium steel 0-0.1; 0-0.16; 0-O.25; 0-0.4; 0-0.6; 0-1; 0-1.6; 0-2.5; 0-4; 0-6; 0-10; 0-16; 0-25; 0-40; 0-600.4 mirror yb-150b0 25 mirror zeroing

○ environmental conditions for use of precision pressure gauge: 5 ~ 40 ℃, relative humidity not greater than 80%, and environmental vibration and pressure source fluctuation 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), the additional temperature error of 0.4% / 10 ℃ must be considered

○ weight of precision pressure gauge: 1kg (type A)? 1.4kg (type b)
