Abstract: An electrical current transducer or transmitter having a meter movement with magnet means movable both by input torque directly to its shaft and by feedback current through stationary coils adjacent to the magnet, a vane mounted on the movement controlling radiant energy, and an energy sensitive means to produce a current level proportional to input displacement of the meter movement. The transducer comprises the output means of several electrical transmitters whose input means proportions the measured condition to torque for actuation of the transducer.
