Product description: Precision pressure gauge is mainly used to verify the ordinary industrial pressure gauge can also be used for precision measurement of copper alloy and alloy structural steel and other non-corrosive, non-crystalline, non-solidification of various media pressure.

Model YB-150A has a mirror ring under the scale line, so that the meter reading is more clear and accurate, beautiful and novel appearance.

Model YB-150B has a mirror ring under the scale line and a zeroing device with an accuracy of 0.25.

Accuracy rating: 0.4 and 0.25

Operating environment conditions: 5 ~ 40℃, relative humidity is not more than 80%, and vibration and pressure source fluctuation should not affect the accurate reading of the instrument.

Temperature impact: use ambient temperature such as deviation from 20± 3℃(Type A) or 20± At 2℃(type B), the additional temperature error of 0.4% /10℃ should be considered.

Weight: 1kg(Type A)? 1.4kg(Type B)

Overall dimension (unit: mm)

Structural principle

The instrument consists of a measuring system indicating part and a housing part. The instrument has a good sealing and sealing device, can protect its internal measuring mechanism from mechanical damage and pollution immersion.

The principle of the instrument is based on the deformation of the elastic element (the spring tube in the measurement system). Under the pressure of the measured medium, the end of the spring tube is forced to produce the corresponding elastic deformation. — Displacement, with the help of a tie rod through the gear drive mechanism transmission and amplification, the measured value is indicated on the dial by the pointer fixed on the gear shaft.
