Current-to-pneumatic (I/P) transducers blend an innovative I/P conversion technology with proven pneumatic instrumentation designs. They combine the best ideas of how to shrug off pipeline vibration and shock with field-proven ways to operate accurately and efficiently.
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.
Fisher 646 electro-pneumatic transducers use a patented converter module that converts a 4 to 20 milliampere input signal to a proportional 0.2 to 1.0 bar (3 to 15 psig) pneumatic output signal.
Fisher 846 electro-pneumatic transducer accepts an electrical input signal and converts it to a pneumatic output signal.
Fisher i2P-100 electro-pneumatic transducer uses a patented converter module that converts a milliampere input to a proportional pressure output.
