ZJ5410型复合真空计可进行105 Pa~10-1 Pa宽量程测试。为ZJ-54D热偶规管研制了配套的扩流恒流源,同时又为ZJ-10电离规管研制了由SM89C52单片机和开关电源模块TOPSwitch相结合的配套电源,本电源是一款新型宽量程复合真空计电源。本计充分发挥了单片机实时性好,容易扩展,运算速度快等功能,实现了热偶计压力值拟合曲线浮点运算,液晶屏多数据信息同时显示,真空度动态显示,真空度长时间记录和曲线显示等功能。
ZJ5410-type composite vacuum gauge can be 105 Pa ~ 10-1 Pa wide range test. ZJ-54D thermocouple regulate the development of ancillary constant current source, while ZJ-10 ionization regulation developed by the SM89C52 microcontroller and switching power supply module TOPSwitch combination of supporting power, the power is a new wide Range of complex vacuum gauge power supply. This meter give full play to the microcontroller real-time, easy to expand, fast operation and other functions, to achieve the thermocouple pressure curve fitting curve floating-point operation, LCD multi-data display at the same time, the dynamic display of vacuum, vacuum for a long time Record and curve display and other functions.
