Potentiometric displacement sensor
A Potentiometric displacement sensor is a sophisticated measurement device that converts linear or rotary motion into electrical signals, providing precise position feedback in various industrial and engineering applications. This sensor operates on the principle of voltage division, utilizing a resistive element and a sliding contact (wiper) to generate an output voltage proportional to the position of the moving element. The sensor consists of a high-precision resistive track, typically made from conductive plastic or wire-wound elements, along which a wiper moves to create varying resistance ratios. The output signal is directly proportional to the position of the wiper, making it an ideal choice for applications requiring accurate position measurement. These sensors can measure displacements ranging from a few millimeters to several meters, offering excellent resolution and repeatability. They provide real-time position feedback with minimal signal processing requirements, making them particularly valuable in automation systems, robotics, and industrial machinery. The robust construction and reliable operation of potentiometric displacement sensors make them suitable for harsh industrial environments, while their simple working principle ensures long-term stability and consistent performance.
