Electro Pneumatic Transducer Model PT-700
The electro-pneumatic transducer PT 700 series provides the proportional conversion from a 4...20 mA input signal to a 0...100% supply pressure output signal. This device provides the interface between the electro-pneumatic positioner and a pneumatic actuator of process industrial
applications (chemical, petro-chemical, refineries etc.).They are easy to adapt and improve the performance of the control loop with optimized dynamic behaviour. The transducer PT 700 series is the first which uses piezoelectric microvalves with low power consumption allowing connection to standard two-wire circuits. No extra power supply is needed and makes the device very compact and robust.
Accurate conversion of the electrical input signal by using a silicon pressure sensor for feedback.
