Product Details

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.

Main FEATURES :

Updating time of output current in 90 ms
Improved performance, increased accuracy and greater stability
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

When pressure or differential pressure is externally input, sensor’s resistance will change and be converted into frequency signals by digital signal, and then sent to microprocessor. The microprocessor will output a current control signal to current output control circuit after its calculation, turning into 4-20mA analog current output and displays finally.
