JS-120 数字绝压表
JS-120 Digital Absolute Pressure Gauges


     应用范围Application
    数字绝压表主要用于监视或测量某些真空设备(如真空包装机械、监测冷凝压力和液体的蒸
气压力的设备等)中**压力的仪表。
    Monitoring of vacuum pumps, packing machines, determination of condensation pressure and vapour pressure in fluids;
    数字绝压表既具有能现场读取压力值的功能，还能输出4~20mA标准信号，便于远程控制**压力是指以**压力零位(**真空)作基准，****压力零位的压力。
    Acquisition and display of process values locally, also can transmit 4 ... 20 mA ** for remote control ;
    **压力值一般可用下式表示：
    Absolute pressure means, the pressure over the absolute zero pressure;
    **压力值 = 真空度(负压)值 + 大气压力值
    Absolute pressure= absolute zero pressure (minus) + atmospheric pressure
