The gas meter generally consists of the following parts:
    1.Power supply and precision pressure reducing valve
    The precision pressure reducing valve provides the working pressure for the measuring instrument and the working voltage for the electrical circuit part of the measuring instrument.
    2.probe
    Probe two important components exhaust tank and nozzle hole. The probe is configured according to the specific size of the workpiece to be measured and can be a ring gauge, plug gauge or other shape.
    3.Pressure transmitter
    The function of the gas pressure transmitter is to convert the pressure signal sensed by the probe into an electrical signal.
    4.MCU control system
    The display unit is used to display the measured value and the measurement judgment result. The key operation unit is used to operate the measuring instrument, and the key operation unit, display unit andCPUComposition: If the parameters are set, the data is saved and uploaded.CPUThe signal converted from the origin converter passes throughADSample,CPUAfter processing, it is converted into a display value and sent to the display unit for visual display.
    5.Standard gauge

    The material of the standard gauge is divided into steel, chromium or cemented carbide, generally according to the tolerance of the upper and lower limits of the standard gauge size, is used for the standard measuring system.

    As a precision parts size pneumatic measurement equipment manufacturers, focusing on micro-precision, R & D and production of digital display pneumatic momentum meter, a variety of models, quality assurance, manufacturers direct sales, price concessions.
