The principle of the pull rod type linear displacement sensor (also known as: electronic ruler, resistance ruler, potentiometer, displacement sensor) : The principle of potentiometer: All sensors are position measurement type, used in regulation systems (control systems) and measurement systems to directly measure displacement and length, and output DC voltage signals. The signals can also be converted into standard 0-5V, 0-10V or 4-20mA DC signals through built-in or external V/A transmission modules. It can also transmit control requirements over long distances. The KTC1 pull-rod type linear displacement sensor (also known as: electronic ruler, resistance ruler, potentiometer, displacement sensor) has an output displacement variation of 0-100% given input working voltage (varying with displacement).
