buy draw wire sensor
A draw wire sensor, also known as a string pot or cable-extension transducer, is a sophisticated measurement device that precisely tracks linear position and distance. This versatile sensor consists of a measuring cable, a spring-loaded drum, and an internal rotary sensor that converts mechanical movement into electrical signals. The measuring wire, typically made of highly durable stainless steel, extends and retracts while maintaining constant tension thanks to the spring mechanism. When the wire is pulled out, the drum rotates, and the internal sensor generates corresponding electrical signals proportional to the distance traveled. These sensors offer measurement ranges from a few inches to several meters, making them ideal for various industrial applications. The device's robust construction ensures reliable operation in challenging environments, while its compact design allows for easy installation in confined spaces. Draw wire sensors support multiple output options, including analog, digital, and incremental signals, providing flexibility in system integration. They excel in applications requiring continuous position monitoring, such as in automated manufacturing processes, material handling equipment, and mobile hydraulic systems. Their high accuracy, combined with minimal maintenance requirements and long operational life, makes them a cost-effective solution for precise distance measurement needs.
