A control system for positioning a remote fluid motor having relatively movable elements. The system includes an electric circuit having a control element producing an output related to the relative position of the movable elements, an adjustable element having an output related to the desired position of the movable elements, and an electric comparing mechanism producing a voltage output which is a combined function of the above outputs and which properly positions a valve to control the flow of fluid to and from the fluid ram. The control includes a cantilever beam within the fluid ram whose deflection is responsive to the position of the piston rod. A variable resistor is connected to the beam having an electrical output related to the position of the piston rod.
