Draw wire displacement sensors are essentially electronic tape measures. With the draw-wire principle, a linear movement is transformed into a rotary movement, which is then converted into a resistance change or into countable increments.
The pull wire sensors measure the linear movement of a component by means of a wire made from highly-flexible stainless steel strands which is wound onto a drum by a long-life spring motor. The measuring drum is axially-coupled with a multi-turn potentiometer, an incremental encoder, or an absolute encoder.
For original equipment manufacturers of machines and systems these draw wire displacement transducers can be customised and adjusted for integration.
Characteristics of the draw-wire sensors:
Measuring ranges up to 50,000 mm
Easy mounting for any application
High reliability and long life cycle
Analogue or digital output available
These draw wire sensors find application in Lift-height measurement in fork-lift trucks, precision synchronised lifting system, vibration displacement measurement in road tests etc.
