Cable Actuated Position Sensors are a versatile position measurement device that converts mechanical motion into an electrical signal that may be metered, recorded, or transmitted. Firstmark Controls cable actuated position sensors consist of a stainless steel displacement cable wound on a threaded drum that is directly coupled to a precision, long-life sensor. Operationally, the sensor is mounted in a fixed position and the extension cable is actuated by a moving object. As movement occurs, the cable extracts then later retracts under the power of an internal, engineered spring which also maintains tension on the displacement cable throughout its stroke. The rotation of the sensor produces an electrical output proportional to the cable's movement giving indication of positional translation.
