Fisher™ 546NS Electro‐Pneumatic Transducer Fisher™ 546 Series Electro-Pneumatic Transducers Fisher 546, 546S, and 546NS transducers receive 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. Specifications Area Classification Explosion Proof, Non-incendive Certifications CSA, FM Communication Protocol 4-20mA Analog Data Interface Wired Diagnostics No Input Signal Electric Mounting Type Remote Mount, Actuator Mounted Operating Temperature Standard Temperature Position Control Modulating Control Process Control Pressure Supply Media Air Other Configurations Contact your local Emerson business partner or sales office to learn about additional specifications or options for this product. Features High natural frequency of torque motor moving parts results in negligible vibration influence. Meets typical seismic requirements for nuclear service. Screw driver adjustments for span and zero are conveniently located and have arrows indicating rotation to increase settings. No additional are parts required to reverse action. Integrated pneumatic relay is mounted outside case and can be removed without disturbing electrical or pressure connections or impairing explosion safety.
