ABSTRACT:
A control system for proportionally operating an actuator is disclosed having a condition responsive device comprising an element movable in response to a sensed condition and a sensing device for sensing the movement of the element, the actuating means being connected to the sensing device for movement in response to the movement of the sensing element and a feedback mechanism responsive to the movement of the motor for repositioning the sensing device and the sensing element relative to one another for providing proportional control.
