String Potentiometers

String Potentiometers

String Potentiometers - often referred to as cable extension transducers, draw wire sensors, or string encoders are an incredibly straightforward solution for measuring linear position. The principle of operation involves a cable winding onto a spring-loaded spool that converts linear displacement into rotation. This rotating motion is then measured using a potentiometer or encoder, which is subsequently transformed into an analog or digital output. String pots are quite user-friendly to install, requiring no critical alignment and offering direct measurement at the point of interest. Our catalog includes a broad range of options in cable-actuated, string pots, and draw wire-type sensors, capable of accommodating a wide variety of applications, even for lengths extending beyond 50 meters. Each data sheet provides a comprehensive list of options to suit your specific needs, whether they pertain to structural testing, automotive testing, civil/structural applications, or specific OEM requirements like boom arms, elevators, and outriggers.
