What is the measuring priciple of draw-wire sensor?

With the draw-wire principle, a linear motion is transformed into a change in resistance by a rotation. A measuring wire made of highly flexible stainless steel wires is wound onto a drum with the aid of a long life spring motor.








  •  Draw-wire sensors for displacement, distance and position measurements up to 50,000 mm
