ABSTRACT:
The invention relates to a process and apparatus for detecting the speed and rotary direction of a rotary drive by using a signal-transmitting or signal-changing element which is connected rotationally secured to the rotary drive. According to the invention, during rotation of the signal-transmitting or signal-changing element a rotary direction coded signal is produced which is detected by a sensor and which is supplied to an electronic evaluator unit. The aim of the invention is to provide a process and device for detecting the speed and rotary direction of a rotary drive which manages with one sensor unit for a high analysis of the speed and rotary direction.
