Abstract
A transducer for providing a modulated fluid pressure control signal having an electromagnetic stator operable in response to an electrical control signal to apply a magnetomotive torque to a rotary valve member for controlling fluid flow to and from a control signal chamber. A diaphragm senses the difference between the control signal chamber pressure and atmospheric pressure and is operable in response thereto for moving the rotor axially for varying the pole overlap and magnetomotive torque on the rotor.
