Fisher 546 Electronic Input Transducer. Input 4-20mA DC, 4-12mA DC, and 12-20mA DC | Ouput 3-15PSI direct action, 15-3psi reverse action | Single electronic circuit board | Supply pressure 3-35PSI 3-15PSI/0-30PSI | Integral Regulator 67AFR | VTC1640880 Gauge | TO BE ASSEMBLED AT VOX TECH Simple Type: Transducer

Fisher 546, 546S, and 546NS transducers receives a direct-current input signal and use a torque motor, nozzle-flapper, and pneumatic relay to convert the signal to a proportional pneumatic output signal. Nozzle pressure, which operates the relay, is also piped to the torque motor feedback bellows. This provides a comparison between input signal and nozzle pressure and corrects errors in nozzle pressure.
