Draw wire potentiometer
A draw wire potentiometer, also known as a string potentiometer or cable-extension transducer, is a precision measurement device that converts linear motion into an electrical signal. This sophisticated sensor consists of a flexible wire wrapped around a spring-loaded drum coupled with a potentiometer or encoder. As the wire extends or retracts, the drum's rotation is translated into an electrical output signal proportional to the wire's displacement. These devices offer measurement ranges from a few inches to several meters, making them versatile tools for various industrial applications. The internal mechanism features high-quality materials and precision engineering, ensuring reliable performance in demanding environments. Draw wire potentiometers excel in applications requiring continuous position monitoring, such as industrial automation, material handling systems, and mobile machinery. Their robust construction typically includes durable housings, protected wire guides, and sealed components to withstand harsh industrial conditions. The technology incorporates advanced features like integrated signal conditioning, multiple output options including analog and digital signals, and compatibility with various control systems. These sensors provide exceptional accuracy and repeatability, making them ideal for precise motion control and position feedback applications.
