YB150A precision pressure gauge and 150B precision pressure gauge are mainly used to calibrate ordinary industrial pressure gauges, and can also accurately measure the pressure of non corrosive, non crystalline, and non solidifying media on materials such as copper alloys and alloy structural steel at the process site.
YB150A precision pressure gauge and 150B precision pressure gauge instruments are equipped with mirror rings (A-type B-type) below the scale line, which provide clearer and more accurate readings during use. And equipped with zero adjustment device (Type B)

■Structural principle:
YB150A precision pressure gauge and 150B precision pressure gauge consist of a pressure measurement system, transmission mechanism, indicator device, and housing. The pressure measuring elastic element has undergone special processing to ensure stable and reliable performance. After being matched and debugged with high-precision transmission mechanisms, it can ensure accurate indication accuracy.
The working principle of YB150A precision pressure gauge and 150B 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

○ Environmental conditions for use: 5-40 ℃, relative humidity not exceeding 80%, and environmental vibration and pressure source fluctuations have no effect on the accurate readings of the instrument.
○ Temperature effect: 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
