String pot sensor
A String pot sensor, also known as a string potentiometer or cable-extension position transducer, is a sophisticated measurement device that combines mechanical and electrical components to provide precise linear position measurements. This versatile sensor consists of a flexible cable wound around a spring-loaded drum, connected to a potentiometer or encoder. As the cable extends or retracts, the sensor converts the linear motion into an electrical signal, providing accurate position feedback. The device operates by maintaining constant tension on the measuring cable, ensuring reliable and repeatable measurements across various applications. String pot sensors are engineered to withstand demanding industrial environments, featuring robust housings and durable materials that protect the internal mechanisms. These sensors can measure distances ranging from a few inches to several hundred feet, making them ideal for both short and long-range applications. The technology incorporates advanced features such as multi-turn capability, various output options including analog, digital, and incremental signals, and compatibility with modern control systems and PLCs. String pot sensors excel in applications requiring continuous position monitoring, such as industrial automation, material handling equipment, medical devices, and automotive testing.
