The function of precision pressure gauge and its instrument composition

The meter is composed of a measuring system, an indicating part and a case part. The measuring system is composed of joints, spring tubes and gear rotation mechanism. Due to the pressure of the measured medium, the end (free end) of the spring tube is correspondingly displaced, and the sector gear in the mechanism is driven by the connecting rod to produce an angular displacement, so that the gear shaft can be deflected and transmitted to the indicating part. The indicating part is divided by the scale. The meter is composed of a measuring system, an indicating part and a watch case part. Measuring system-consists of joints, spring tubes and gear rotation mechanism. Due to the pressure of the measured medium, the end (free end) of the spring tube is correspondingly displaced, and the sector gear in the mechanism is driven by the connecting rod to produce an angular displacement, so that the gear shaft can be deflected-transmitted to the indicating part. Indicating part-consists of index plate, mirror surface (YB-201 type without mirror surface and pointer, etc.). The pointer will indicate the deflection value of the gear shaft correspondingly on the index plate to indicate the pressure value of the measured medium. Case part ——Composed of the watch cover, watch glass and cover, etc. The lower end of the watch cover is equipped with a zero adjustment device for adjusting the zero position to maintain the accuracy of the zero value and reading.
