Functional Principle, Technical Data

2.
2.1
The draw-wire principle transforms a linear movement into a change in resistance.
A measuring wire made of highly flexible stainless-steel cores is wound onto a drum by using a durable
spring motor.
The winding drum is coupled axially with a potentiometer made of conductive plastic.

2.2
The draw-wire principle is applied in housing designs 40-MT, 80-MT and 130-MT with different measuring
ranges from 40 to 130 mm.
The electrical connection is the potentiometer output (resistance divider).
