    Introduction


    ZDF-X series resistance/ionization compound vacuum gauge can independently complete low vacuum (1×105~1×10-1Pa) measurement based on the one resistance unit. Another resistance unit (ZJ-52T resistance gauge) and ionization unit (ZJ The -27 ionization gauge) work as a composite unit to complete continuous measurement and control of 1x105~1x10-5Pa. Therefore, this series vacuum gauge has all technical parameters and performance characteristics of resistance vacuum gauges and ionization vacuum gauges, at the same time, it has new functions. 


    The composite unit of this vacuum gauge has two operating modes: manual mode and automatic mode. When working in manual mode, it is equivalent to an independent thermocouple vacuum gauge and ionization vacuum gauge. When working in automatic mode, the resistance unit first begins the measurement, when the vacuum degree measured by resistance unit higher than vacuum degree that the ionization gauge can open, the ionization gauge filament is automatically illuminated (turned on) and begins high vacuum measurement, which enables automatic continuous measurement from low to high vacuum. The peripheral (PLC) opening and closing ionization gauge function has also been added to realize the ionization gauge working in the vacuum environment, so that the working life of the ionization gauge is extended. 


    Some models adopt switching power supply and switching DC power drive stabilized ionization gauge filament launching circuit, which realizes the design of highly integrated non-power frequency transformer, and the cold state preheating slow start of ionization gauge filament, it also overcomes the overshoot phenomenon of cold state initiates of ionization gauge filament, also prolongs the service life of gauge, and then realizes a wide AC power adaptability (AC/90V ~ 260V), as well as the wide cable length adaptive capability (3-30 meters). It is currently the novel ionization gauge filament drive stabilization technology. In order to adapt to vacuum equipment automation technology, it integrates powerful relay contact control, serial communication, vacuum analog and other extended functions. So, it is especially suitable for vacuum measurement from atmospheric pressure (normal pressure) to high vacuum of vacuum equipments whose ultimate vacuum is on the order of 10-3~10-4Pa with the working vacuum is on the order of 10-2~10-3Pa.
