WebA string potentiometer is a linear position sensor, also known as a string pot, draw wire position sensor, Cable Extension displacement transducer, or a yo-yo pot. It is a cable-actuated position or displacement transducer utilized for linear position measurement and velocity using a flexible cable (string) and a spring-loaded spool. WebThe working principle depends on the potential across any portion of the wire which is directly proportional to the length of the wire that has a uniform cross-sectional area and current flow is constant. Following is the derivation used to explain the potentiometer …
