ZDF-Ⅲ series resistance / ionization composite vacuum gauge is based on the combination of low vacuum measurement resistance unit (ZJ-52T resistance gauge) and high vacuum measurement ionization unit (ZJ-27 ionization gauge) technology to complete 1 × 105 ~ 1 × 10 -5Pa continuous measurement and control. Therefore, this vacuum gauge series has all the technical parameters and performance characteristics of resistance vacuum gauge and ionization vacuum gauge; meanwhile, it adds new functions. The vacuum gauge series has two working modes: manual mode and automatic mode. When working in manual mode, it is equivalent to an independent resistance vacuum gauge and ionization vacuum gauge. When working in automatic mode, the resistance unit first enters the measurement. When the resistance unit's measurement vacuum is higher than the vacuum that can be turned on by the ionization gauge, the ionization gauge filament is automatically Light up (turn on) and enter the high vacuum measurement, and realize automatic continuous measurement from atmospheric pressure (normal pressure) to high vacuum. The function of opening and closing the ionization gauge of the peripheral device (PLC) has also been added to achieve the optimal operation of the ionization gauge in the vacuum environment and maximize the working life of the ionization gauge. Some models use switching power supply and switching DC power supply to drive the stable ionization gauge filament transmitting circuit, which realizes a highly integrated non-frequency transformer design, realizes the cold start warm-up of the ionization gauge filament, and overcomes the ionization gauge filament. The cold start overshoot phenomenon prolongs the regulatory life, achieves a wide range of AC power adaptability (AC / 90V ~ 260V), and achieves a wide cable line length adaptive ability (3-30 meters). Is the most novel ionization gauge filament drive stabilization technology. In order to adapt to the vacuum equipment automation technology, it integrates powerful relay contact control, serial communication, vacuum analog and other extended functions. It is especially suitable for vacuum application equipment. The ultimate vacuum is on the order of 10-3-10-4Pa, and the working vacuum is on the order of 10-210-3Pa. From atmospheric pressure (normal pressure) to high vacuum measurement and control.
