摘要
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 compsite vacuum gauge can complete wide-range test from 105 Pa to 10-1 Pa.The extendable constant current source was developed for the ZJ-54D thermocouple gauge,and the surpporting power supply combined SM89C52 microcontroller with switching power supply module TOPSwitch was developed for ZJ-10 ionization gauge,which is a new power supply for wide-range composite vacuum gauge.This gauge gives full play to the real-time performance,easy to extend,computing speed of microcontroller, and realizes the thermocouple gauge pressure fitting curve floating point arithmetic,simultaneous display of multi-datas on LCD panel, dynamic display and long time record of vacuum degree,curve display and other functions.
