在化工行业中常常需要测量压力值,目前使用的压力表只能测绝对压力值,而不能测相对压力值。在实际生产中只能靠手工计算相对压力值,既费时又费力还容易出错。因此设计一种能测量相对压力值的仪表,将会给实际生产带来很大的方便。智能真空压力表能实时监测大气压力值、绝对压力值和相对压力值,同时提供自动报警和网络通信接口,便于工厂自动化管理。
In the chemical industry often need to measure the pressure value, the current pressure gauge can only measure the absolute pressure value, but can not measure the relative pressure value. In actual production can only rely on manual calculation of the relative pressure value, both time-consuming and laborious but also prone to error. Therefore, the design of a measure of the relative pressure value of the instrument, will bring great convenience to the actual production. Intelligent vacuum gauge real-time monitoring of atmospheric pressure values, absolute pressure values and relative pressure values, while providing automatic alarm and network communication interface for easy factory automation management.
