buy draw wire sensor
A draw wire sensor, also known as a string potentiometer or cable extension transducer, is a sophisticated measurement device that combines precision engineering with versatile functionality. This sensor consists of a flexible wire wound around a spring-loaded drum, connected to a sensor element that converts mechanical movement into electrical signals. The device measures linear displacement by tracking the extension and retraction of the wire, providing accurate position feedback in real-time. The sensor's internal mechanism includes a high-precision potentiometer or encoder that transforms the rotational movement of the drum into electronic signals, enabling precise measurement of distance and position. Modern draw wire sensors feature robust construction with weather-resistant housings, making them suitable for both indoor and outdoor applications. They offer measurement ranges from a few inches to several meters, with exceptional accuracy ratings typically within 0.1% of full scale. These sensors integrate seamlessly with various control systems through standard output signals, including analog voltage, current outputs, or digital interfaces. Their versatility makes them invaluable in industrial automation, material handling equipment, medical devices, and architectural applications, where reliable position monitoring is crucial.
