Basically mount the string pot safely and interface the link to the moving part to be estimated. The string pot’s voltage output is inversely proportional to the cable’s displacement when the potentiometer is powered.
A string potentiometer, draw wire position sensor, Cable Extension displacement transducer, or yo-yo pot are all forms of linear position sensors. It is a position or displacement transducer that uses a flexible cable (string) and a spring-loaded spool to measure linear position and velocity.
Draw wire sensors are compact, low-cost linear transducers that precisely measure an object’s velocity, change in velocity, or position.
A string potentiometer transducer is made up of a precision measuring wire and a sensor (such as a high precision potentiometer or encoder) that use a potentiometric voltage divider to turn the wire’s linear displacement into a proportional electrical signal.
Due to their dependability and ease of assembly, the maintenance-free draw wires are utilised in every industry sector.
The Global String Potentiometer Sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Draw-wire sensors, also known as string potentiometers, string encoders, or draw wire transducers, are small tools for measuring an object’s speed and position along a linear system.
A simple three-part assembly of a measuring wire, a spring-loaded drum or spool, and a sensor (potentiometer) makes them a low-cost option with numerous industrial applications.String potentiometers from P3 America can measure displacements of 50 millimetres to 42 meters.
They are ideal for robust handling in harsh terrain and outdoor environments because they function without precise linear guidance. Find the right draw-wire sensor for your needs by looking through the options presented here. They have the ideal string potentiometer model for any industrial application, including offshore ports, mobile hydraulics, or any other.
