draw wire sensor
A draw wire sensor, also known as a string pot or cable extension position sensor, is a sophisticated measuring device that precisely determines linear position or displacement. This versatile instrument consists of a flexible wire wound around a spring-loaded drum, coupled with a rotary sensor that translates mechanical movement into electrical signals. When the wire is extended or retracted, the internal measuring system accurately records the distance traveled, providing highly precise position measurements. The sensor's core mechanism employs advanced rotary encoding technology, which can be either incremental or absolute, ensuring reliable position feedback in real time. These sensors are engineered to withstand demanding industrial environments, featuring robust housings and durable materials that protect the sensitive internal components. They offer measurement ranges from a few inches to several meters, with resolution capabilities that can reach micrometers in high-precision applications. The integration capabilities of draw wire sensors are particularly noteworthy, as they can easily connect with various control systems through standard industrial interfaces, including analog outputs, digital signals, or industrial fieldbus protocols. Their compact design and flexible mounting options make them ideal for applications where space is limited but precision is essential.
