Device for monitoring progression of strip-like material between two spaced-apart sites in path of sensor for agricultural applications has emitter assigned to sensor and a receiver for optical waves

摘要

Device for monitoring the progression of strip-like material (22) between two spaced-apart sites in the path of a sensor (32) comprises an emitter (40) assigned to the sensor and a receiver (42) for optical waves. The optical waves are directed onto the moving path of the material between the two spaced-apart sites. An independent claim is also included for a winding arrangement (10) containing the above monitoring device. Preferred Features: The emitter and the receiver are arranged on one side and a reflector (44) is arranged on the other side. The sensor and the reflector are fixed. The signal processing unit (34) is connected to a sensor to determine the rotary movement of a rotor.
