LR Micro Self-Resetting Series Displacement Sensors (also known as: electronic rulers, resistive rulers, potentiometers, linear displacement sensors) Principle: Based on the potentiometer principle, all sensors are position-measuring devices used in control systems and measurement systems to directly measure displacement and length. They output a DC voltage signal, which can be converted into standard 0-5V, 0-10V, or 4-20mA DC signals via built-in or external V/A transducer modules, and can also meet requirements for long-distance signal transmission. The LR Micro Self-Resetting Series Displacement Sensors (also known as: electronic rulers, resistive rulers, potentiometers, linear displacement sensors) output displacement changes ranging from 0–100% of the applied operating voltage (which varies with displacement).
