Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A string potentiometer is a transducer used to detect and measure linear position and velocity using a flexible cable and spring-loaded spool. Other common names include string pot, cable-extension transducer, draw wire sensor, and yo-yo sensor.String potentiometers are composed of four main parts: a measuring cable, spool, string, sewing machine, and rotational sensor. Inside the transducer's housing, a stainless steel cable is wound on a precisely machined constant diameter cylindrical spool that turns as the measuring cable reels and unreels.To maintain cable tension, a torsion spring is coupled to the spool. The spool is coupled to the shaft of a rotational sensor (a potentiometer or encoder). As the transducer's cable extends along with the movable object, it causes the spool and sensor shafts to rotate. The rotating shaft creates an electrical signal proportional to the cable's linear extension or velocity.
