ABSTRACT:
Apparatus for determining rotational speed includes a sensor for generating electrical pulse signals representative of rpm in a conventional manner. The electrical pulses are converted to light pulses at the sensor and transmitted to an evaluation circuit, where they are reconverted into electrical pulses that are processed by the evaluation circuit. Interference signals that a rise during the transmission of electrical pulses to the evaluation circuit are thereby eliminated.
