  Principle of hydraulic sensor:
  当液体介质流经集成传感器,流体压力应用于不锈钢安装在传感器住房,然后转移到扩散硅膜片密封硅油,同时参考一端的压力是应用于隔膜的另一边。通过这种方式,隔膜两边的压力差产生了一个应力,这个应力压缩隔膜的一边并拉动另一边。一对应变片位于压缩区,另一对位于拉伸区。两对应变计连接成一个全动态桥,以增加输出信号。该桥由恒流电源供电,以减少环境温度的影响。当压力变化时,由于桥臂电阻值的变化,输出电压也随之变化。差分归一化放大器经过放大转换后,将输出电压转换为相应的电流信号。通过非线性整流回路对电流进行补偿后,将输入压力信号生成近似线性关系的直流4-20ma标准输出信号。
  When the liquid medium flows through the integrated sensor, the fluid pressure shall be applied to the stainless steel mounted sensor housing, and then transferred to the diffused silicon diaphragm seal silicone oil, while the pressure at the reference end shall be applied to the other side of the diaphragm. In this way, the pressure difference between the two sides of the diaphragm creates a stress that compresses one side of the diaphragm and pulls the other. One is located in the compression region and the other in the stretching region. Two corresponding transformers are connected into a full dynamic bridge to increase the output signal. The bridge is powered by a constant current power supply to reduce the impact of ambient temperature. When the pressure changes, the output voltage changes with the change of the resistance value of the bridge arm. After amplification and conversion, the differential normalization amplifier converts the output voltage to the corresponding current signal. After the current is compensated by the nonlinear rectification circuit, the input pressure signal is generated into a DC 4-20mA standard output signal with approximate linear relationship.
