Technical Field

Background

A vacuum gauge is an instrument that measures the pressure of a gas in a vacuum system. The vacuum measuring instrument is generally composed of a display control unit, a signal wire and a vacuum gauge tube. When the vacuum gauge is used for vacuum test equipment or vacuum processing equipment, the display control unit is arranged on the operation console, and the vacuum gauge is arranged on a working chamber, a pipeline and a pump opening of the equipment. In daily use and calibration and test of a vacuum gauge, zero-point and full-scale adjustment potentiometers of the vacuum gauge are arranged in a vacuum display control unit, one channel corresponds to one vacuum gauge, and one vacuum gauge corresponds to one group of zero-point and full-scale adjustment potentiometers.

The following problems and disadvantages exist with current vacuum gauge designs: when the vacuum gauge is polluted and damaged, the vacuum equipment cannot be used when the gauge is replaced and the measurement is not accurate; after calibration, the measurement channel is fixed with the gauge tube, and the channel cannot be calibrated with qualified gauge tubes by using other channels. The current solution to the problem is to replace the gauge and feed the metering mechanism for recalibration.
