Cable linear displacement transducer

Capteur à câble

Cases of application

In the context of product validation, position or linear displacement measurement is very often required. While many displacement transducers provide extremely accurate and repeatable measurement, even under extreme conditions (inductive, LVDT, Eddy Current, etc.), in many situations, the expectation is to have a much simpler to implement, more cost effective, and robust solution.

Technology

This is precisely where the cable (or wire) displacement sensor comes into its own.

How it works - Wire Sensor](https://www.pm-instrumentation.com/storage/4059/HOW-THEY-WORK.png)

The sensor contains a cable wound around a spool, the end of which is attached to the element whose displacement is to be measured. The elongation of the cable is converted into an electrical signal (current, voltage, potentiometric, impulse) directly proportional to the displacement. The conversion is done by Hall effect, without contact, allowing a very high number of cycles to be reached. The cable is directly or indirectly linked to the displacement to be measured, which allows a non-normal or non-linear displacement. The measurement can be offset by cable extensions. The sensor body and the cable can be attached to the fixed or moving part of the measurement.

The benefits

  • Extremely fast and cost-effective installation and commissioning
  • Long service life
  • Wide range of measuring ranges: from a few mm to 50 metres
  • Many configuration possibilities: cable type, hanging, output signal, waterproof versions, fixing kits, etc.
