Wire displacement sensor
A wire displacement sensor, also known as a draw wire sensor or string pot, is a sophisticated measurement device that precisely tracks linear position and movement. This versatile instrument consists of a flexible wire wound around a spring-loaded drum, combined with a rotary sensor that measures the extension and retraction of the wire. As the wire extends or retracts, the drum rotation is converted into electrical signals that accurately represent distance measurements. The sensor's robust design incorporates high-grade materials, ensuring reliable performance in various industrial environments. These sensors offer measurement ranges from a few millimeters to several meters, with exceptional accuracy levels of up to ±0.1% of full scale. The device's compact form factor allows for easy integration into existing systems, while its durable construction withstands harsh operating conditions. Wire displacement sensors feature various output options, including analog, digital, and incremental signals, making them compatible with most modern control systems and data acquisition equipment. Their versatility extends to applications in automotive testing, structural health monitoring, industrial automation, and research facilities where precise position measurement is crucial.
