隔膜在被测介质压力作用下产生变形，密封液被压，形成一个相当于P的压力，传导至压力仪表，显示被测介质压力值。
Divide in measured media deformation under pressure, was sealed by pressure to form a pressure equivalent to the p, conduction to pressure instruments that measured media pressure value.
仪表的作用原理是基于弹性元件（测量系统上的膜片）变形。
Operation principle of the meters is based on distortion of elastic components (diaphragm used in measuring system).
本仪表采用电感调频式传感器直接输出表征位移的数字信号，经单片机处理后，即可显示拉压变形量。
Utilizing variable frequency transducer to get the displacement signal directly, the multimeter can show the tension or compression deformation after the micro-processing of signal.
