HART Protocol Threaded Pressure Transmitter
WE3051TG(TA) series threaded pressure transmitter with HART protocol is a digital capacitive pressure transmitter designed for industrial pressure measurement applications, 4-20mA+ Hart Protocol.
3051TG(TA) series threaded pressure transmitter with HART protocol is a digital capacitive pressure transmitter designed for industrial pressure measurement applications. Except this thread mounted model, the diaphragm flanged mounted is also widely used too . Our 3051TG(TA) offer configurations for gauge pressure, absolute pressure and vacuum including integrated solutions for industrial applications.

- Two years stability of 0.15%
- 0.1% accuracy
- Parameter setting by keypad directly
- 4-20 mA output plus direct digital HART communication
- Automatic zero calibration by press-button
- Explosion proof and water proof housing
The resistance of the sensor will change in response to an external input of pressure or differential pressure. A digital signal will then transform the resistance into frequency signals, which will be supplied to the microprocessor. After doing calculations, the CPU will output a current control signal to the current output control circuit, which will ultimately result in a 4–20 mA analog current output and display.
