MIRAN Technology's pull rope/wire displacement sensor is also known as a pull rope ruler, pull wire displacement meter, pull wire crack meter, and pull wire encoder. Its working principle is simple and convenient. It involves pulling the steel wire rope at the sensor's outlet. The steel wire rope is wound around a pulley inside the sensor. When pulled, the other end of the sensor is connected to the mechanical motion, converting the mechanical motion into an electrical signal to obtain the required data. The structure design of Milang Technology's rope displacement sensor is reasonable, with a small size, strong anti-interference ability, good stability, long service life, wide measurement range and easy installation. It is widely applied in fields such as the Internet of Things, automated measurement systems, construction machinery, and gate opening degrees.
