The operation of draw wire sensor！

Operation, the rope-type displacement sensor installed in a fixed position, pull the rope tied to the moving object. Straight line movement of the rope and movement of the movement axis alignment. When the movement occurs, the drawstring stretches and contracts. An internal spring ensures that the tension of the rope is constant. The threaded hub drives the precision rotary sensor to rotate and outputs an electrical signal proportional to the travel distance of the rope. Measuring the output signal gives the displacement, direction, or rate of the moving object.
