String pots (String potentiometers), also called cable extension transducers or draw wire sensors are a wonderfully simple concept for measuring linear position. The cable winds onto a spool which is sprung loaded converting linear measurement into rotation. This rotation is measured using a potentiometer or encoder which is in turn converted to an analogue or digital output. They are easy to install, no critical alignment is needed and makes a direct measurement at the point of interest. A wide variety of options in regards to cable actuated, string pots, draw wire type sensors to cover many applications for lengths beyond 50,000mm.
