  • Sensor for measuring rotational speeds as well as for the simultaneous determination of direction of rotation
    Patent number: 8330451
    Abstract: A measurement of a lower and a higher speed of rotation is taking place via the inductive sensor. A sensor unit, which comprises a pulse generator, a transmitter side and a receiver side, is used for determining the speed of rotation, whereby the transmitter side comprises a transmitter inductor connected with an oscillator, and the receiver side comprises two receiving inductors. The signal, which is generated by the two receiver inductors and transmitted along each of the signal paths, is forwarded to two signal processing units. Through each of the two signal paths, for lower and higher speed of rotation, the processed signal is forwarded to a logic device.
