draw wire sensor types
Draw wire sensors, also known as string pot sensors or cable extension position sensors, represent a sophisticated yet reliable solution for precise linear position measurement. These devices consist of a measuring wire wound onto a spring-loaded drum, combined with a rotary sensor that translates the wire's linear movement into electrical signals. The fundamental operation involves the wire extending or retracting, while the internal mechanism accurately measures the distance traveled. Available in various configurations, draw wire sensors can measure distances ranging from a few millimeters to several meters with exceptional accuracy. They incorporate different types of output signals, including analog, digital, and incremental encoders, making them versatile for various industrial applications. The robust construction typically features stainless steel wires and durable housings, ensuring reliable operation in challenging environments. These sensors excel in applications requiring continuous position monitoring, such as industrial automation, mobile hydraulics, stage technology, and materials handling equipment. Their compact design and simple installation process make them particularly valuable in space-constrained applications. Modern draw wire sensors often include advanced features like built-in signal processing, temperature compensation, and various mounting options to accommodate different installation requirements.
