YB-150A、150BPrecision pressure gaugeMainly used for verifying industrial ordinary pressure gauges and precision pressure gauges It is also possible to 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.
Precision pressure gauge There is a mirror ring (A-type B-type) set below the scale line, which provides clearer and more accurate readings during use.Medium energy instruments are preferred for pressure gaugesEquipped with a zeroing device (Type B)

■ Structural principle of precision pressure gauge:
A precision pressure gauge consists of a pressure measuring system, a transmission mechanism, an indicator device, and a housing. Precision pressure gauge The pressure measuring elastic element has undergone special processing to make Precision pressure gauge Stable and reliable performance, coupled with high-precision transmission mechanisms for debugging, can ensure precise indication accuracy.
Precision pressure gauge The working principle 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.Medium energy instruments are preferred for pressure gauges.

Main technical indicators of precision pressure gauge:
○ Measurement range, accuracy level and characteristics of precision pressure gauge

○ Environmental conditions for the use of precision pressure gauges: 5-40 ℃, relative humidity not exceeding 80%, and environmental vibrations and pressure source fluctuations have no effect on the accurate readings of the instrument.
○ Temperature effect of precision pressure gauge: When the operating environment temperature deviates from 20 ± 3 ℃ (type A) or 20 ± 2 ℃ (type B),Medium energy instruments are preferred for pressure gauges. Then the temperature additional error of 0.4%/10 ℃ must be considered
