Draw Wire Sensor ！

Rope displacement sensor function is to convert mechanical motion can be measured, recorded or transmitted signals. The displacement sensor consists of a stretchable cord wound on a stainless steel threaded round, round with a sophisticated sensors are linked together, the sensor can be incremental encoders, absolute encoders, mixed or conductive plastic Hu rotary potentiometers, synchronous or resolver.
Operation, rope displacement sensor is mounted in a fixed position on the rope tied to the object. Rope linear motion and moving objects movement axis aligned. When movement occurs, the rope stretch and contraction. An internal spring to ensure the tightness of the rope. Threaded wheel driven precision rotary sensor is rotated, the output of a rope moving distance proportional to the electrical signal. Measuring the output signal of the displacement of the moving object can be obtained. Direction or rate
