pressure transducer 1. Make a pressure measuring instrument, coupled with the secondary instrument to read out the pressure value and record the pressure change process. After the calibrated pressure reading, the accuracy is higher than the pressure gauge, and the remote telemetry of the pressure is performed.
2. Pressure safety protection can be applied.
3. The automatic control of the pressure system operation can be carried out.
Therefore, the pressure sensor is a commonly used instrument that implements automatic control of pressure machinery.
Simply put, a pressure sensor is a pressure signal that is converted into an electrical signal: 0~10V, or a 4~20mA current signal. The different pressure values it feels are corresponding to a certain value within this range. One current value, or voltage value, these signals can be transmitted to the automation control equipment, such as the inverter, servo, etc., can also be transmitted to the PLC, industrial control computer and other host computer, in order to achieve the automation of the operation process / unattended.
