Draw Wire Sensors (String Potentiometers)

Draw-wire sensors, also called string potentiometers, string encoders, or draw wire transducers, are compact devices used for accurately measuring an object’s position and speed along a linear system. They are a low-cost solution with a very wide range of industrial applications that consist of a simple assembly of three main components — a measuring wire, a spring-loaded drum or spool, and a sensor (potentiometer).

P3 America’s range of string potentiometers are capable of measuring displacements from 50 millimeters to 42 meters. They work without precise linear guidance and are perfect for robust handling in outdoor environments and rugged terrain.

Whether you need a solution for offshore ports, mobile hydraulics, or any other industrial application, we have just the right string potentiometer model for you.
