The working principle and structure design of ZJK-β vacuum gauge are introduced, and its performance is studied. The instrument and β emission ionization gauge with the rocket for the end of the total pressure measurement, measurement range of 0.1 ~ 5000Pa. The instrument adopts single-chip microcomputer control, which can realize automatic conversion of range, linear correction and automatic pressure calibration. It can perform real-time monitoring of measured pressure, dynamic trend display, data storage and other functions. Performance research results show that, ZJK-β-type vacuum gauge in the measurement range with good linearity, reliable measurement data, providing a rocket launcher security.
