  • Method for the reliable determination of the distance of the conductive reaction track from a functional surface of a magnetic levitation vehicle moving relative to the reaction track and a sensor for performing the method
    Patent number: 5764050
    Abstract: In a method for measuring a distance between a conducting reaction track and a functional surface moving relative to the reaction track a sensor with two signal transmitters is provided on the functional surface. An alternating field is generated in the sensor. The alternating field changes as a function of the distance between the conducting reaction track and the functional surface. Each of the two signal transmitters detects the changes of the alternating field as distance information. Each signal transmitter produces decoupled distance information values. These decoupled distance information values are processed in separate distance measuring channels to provide processed signals. The processed signals are constantly fed to and compared in a comparator. A distance information signal is emitted only when the processed signals of the separate distance measuring channels are identical within a predetermined tolerance range.
