打印本文       小   中   大

YB-150B type in the scale of the line with a mirror ring, and with a zero adjustment device, the accuracy of 0.25. The precision pressure gauge is mainly used to check the general pressure gauge for industrial use. It can also be used to measure the pressure of non corrosive, non crystalline and non solidification of copper alloy and alloy structural steel. -150A YB type in the standard line with a mirror ring, so that the instrument readings are more precise and accurate, beautiful and novel appearance.

Main technical indexes of precision pressure gauge

Accuracy level: 0.4 and 0.25

Meter connection: standard thread X1.5 M20 (optional)

65Mo pointer: black manganese blade

The use of environmental conditions: 5 ~ 40 degrees Celsius, the relative humidity is not more than 80%, and the fluctuations of the environment and the pressure of the source of the accurate reading of the meter has no effect.

Temperature effect: the use of environmental temperature, such as deviation from 20 + 3 degrees Celsius A or 20 + 2 degrees Celsius, the temperature should be taken into account the additional error 0.4%/10.

Weight: 1.4kgB type 1kgA

Structure principle of precision pressure gauge

The instrument is composed of an indication part and a shell part of the measuring system. The instrument has good sealing performance and is provided with a sealing device, which can protect the internal measuring mechanism from mechanical damage and contamination.

The principle of the instrument is based on the elastic element measurement system in the spring tube deformation. Under the pressure action of the medium to be measured, forcing the end of spring tube produces the corresponding elastic deformation, displacement, with in tension rod of the gear transmission mechanism of transmission and amplification, is composed of a fixed to the gear shaft of the pointer by measured pressure value will be indicated on the dial.
