Often referred to as a string pot, a yo-yo pot, a draw wire transducer, a linear position transducer, or a cable extension transducer, the device has proven to be an attractive approach for a multitude of applications in many different industries. With relatively non-critical alignment requirements, compact size, and ease of installation, wire rope actuated transducers are the linear position measurement system of choice in applications as diverse as bone densitometers in the medical industry, crash testing in the automobile industry, pump jacks in the crude oil extraction industry and irrigation and flood control in the water management industry. With a variety of available electrical outputs that include voltage, 4 to 20 mA current and digital, UniMeasure linear displacement transducer products provide an extremely cost effective method for linear position and velocity feedback.
