Product Details

4-20mA HART Differential Digital Hydraulic Pressure Air Sensor

Product feature of the pressure transmitter

1 Adoption of microprocessor enhances its flexibility and function;

2 Have strong self-diagnostic capability;

3 Without mutual effect between zero adjustment and range adjustment;

4 Complete function of remote & local setting and calibration;
