Draw wire sensors measure the position and the movement of an object with a flexible wire which is wound around a spring-loaded spool. They permit measurement of a (mostly) linear change of position over greater displacement distances with simple installation and tolerance in respect to mild lateral motion of the object.
There are numerous variants available:
- measurement distances of up to more than 40 m,
- various cable types,
- compact plastic versions up to rugged metal housings,
- analog and digital signal outputs/interfaces.
