Wire transducers

Linear wire transducers

Stout, easy to install, highly protected against environmental agents: ELAP linear wire transducers series HLS and HPS are the ideal solution for those industrial applications which require high accuracy and measuring length up to 12 metres; typical applications are: X-Y tables, hydraulic and pnematic cylinders, packing machines, and wood-, glass-, marble-, sheet-working machineries.
The transducer consists of an encoder or a potentiometer operated by means of a wire-reel mechanism; the wire is out of stainless steel covered with nylon.
The potentiometer HPS provides an analogue signal proportional to the linear displacement of the wire, while the encoder HLS provides a number of pulses proportional to the linear displacement of the wire. The inside spring controls the return of the wire to the starting position.
For both types the travel speed is 1000/2000 mm/sec., depending on the stroke, and the protection degree granted by the stout anodysed aluminium case is IP64. The connection is by means of a cable 1 m long. The operators will surely appreciate the mounting method, which is particularly easy.

Transducers seris WPS & WDS consist of the wire-reel mechanism combined with an absolute multiturn high-resolution encoder with communication  protocol EtherNet/IP, EtherCAT, PROFINET, Profibus, CANopen or SSI serial output.

Wire transducer development and production

Linear wire transducers are devices used to measure the linear movement of an object. This result is obtained via winding a wire on a specific drum, with a rotary potentiometer or encoder — be it incremental or absolute — to then calculate the effective displacement. With a potentiometer, in fact, this will provide an analogue signal, whilst the encoders will return a number of pulses—both being quantities proportional to the displacement of the wire.


Linear wire transducers are devices that are basically comprised of two components: the mobile part in ultra-flexible nylon-coated steel wire, along with a rotary potentiometer or encoder—being either absolute or incremental—to interpret the movement. The winding of the wire around the drum is actually read by these devices, transforming the linear movement of the position transducer into a rotary movement (that of the drum axis) first of all and then—through additional devices—either into a variation of electrical resistance or into an increase of notches. The primary advantage of such architecture is the possibility of reduce the size of a device that, once activated, is capable of measuring distances even up to several metres.


The wire transducers are distinguished by robustness and reliability, making them particularly suitable for industrial applications in which precision measurements and lengths of up to 12 metres are required but in which a compact design is also desired. Depending on the needs, various communication interfaces and protocols are available: EtherCAT, PROFINET, Profibus, CANopen or SSI. Amongst the industries most often employing such transducers are:

  • The medical device industry
  • The elevator and lifters industry
  • The hydraulic and pneumatic cylinder industries
  • The packaging industry
  • The marble industry
  • The wood industry
  • The sheet metal industry

Custom models

In addition to a series of widely-used standard models, ELAP develops and produces custom wire transducers, devised to measure displacements in the customer’s specific industrial processes. Thanks to the extremely vast possibility of configuration and calibration of our instruments and to our internal design studio, ELAP products can be tailored to any specific need you may have.
