    摘要: In one embodiment, a method for determining the distance of a conducting surface profiled in a direction of distance determination from a functional surface moving relative to the profiled surface is disclosed. The method includes connecting inputs of a sensor to an oscillator arrangement. The sensor includes a first and a second measuring coil. The method includes further connecting outputs of the sensor to an analog-to-digital converter via a demodulator unit to obtain first and second digital measured values. The first and second digital measured values correspond to the distance between the profiled surface and the first and second measuring coil of the sensor, respectively. The method further includes connecting an arithmetic unit to the analog converter unit. The second measurement coil is arranged at a known distance from the first measuring coil on the side of the first measuring coil that faces away from the profiled surface. The method finally includes calculating, using the first and second digital measured value and a reference digital value and the fixed distance, a distance measured value giving the distance of the functional surface from the profiled surface. The reference digital value corresponding to the measured value from a reference coil. The reference coil is assigned to the first and second measuring coils and the reference coil is located outside the range of influence of the profiled surface.

    摘要: A method and a system are disclosed for determining the distance between a conducting surface which is profiled in the direction of distance determination and a functional surface moving in relation to the surface by using a measuring system. Two exploring coils are applied to an oscillator system and are connected on the output end to an analog-to-digital converter via a demodulator, the analog-to-digital converter being connected to an arithmetic module. In at least one embodiment of the invention, a method and a system are provided which allow to effect a distance measurement substantially uninfluenced by the profile of the conducting surface and by variations in ambient temperature. For this purpose, a sensor is used whose second exploring coil is mounted on the first exploring coil facing away from the surface at a defined, known distance. An arithmetic module calculates the distance of the functional surface from the profiled surface using the digital measured values to the two exploring coils and a digital reference value and the fixed distance.
