LR micro self-restoring series displacement sensors (alias: electronic ruler, resistance ruler, potentiometer, linear displacement sensor) principle: potentiometer principle, all sensors are position measurement type, used in adjustment systems (control systems) and measurement systems to directly measure displacement and length, output DC voltage signals, or convert signals into standard 0-5V, 0-10V or 4-20mA DC signals through built-in or external V/A transmission modules, and can also transmit control requirements over long distances. LR miniature self-restoring series displacement sensor (alias: electronic ruler, resistance ruler, potentiometer, linear displacement sensor) output displacement change: 0-100% of the given input working voltage (changes with the displacement).
