Abstract

A variable point position determining arrangement includes a housing having a stationary portion secured to a fixed member as, for example working cylinder, and an extendable portion secured to a member movable in relation to the fixed member, as for example piston rod. An elastic element, such as a tension spring, is connected between the stationary portion and an extendable portion of the housing. Such elastic element is stretched or relaxed an amount proportionate to the travel of the movable member. The displacement transducer having an actuator rod and a projecting pin connected to the elastic element at approximately a middle point, follows movement of the elastic element and outputs a distance signal which is a function of the movement of the actuator rod and elastic element. The distance signal can be fed to a control circuit to derive the position value of the movable member therefrom.
