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.
- Updating time of output current in 90 ms
- Improved performance, increased accuracy and greater stability
- Two years stability of 0.15%
- 0.1% accuracy
- Â Parameter setting by keypad directly
- Â 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.
