Abstract: The invention relates to a distance measuring device and a suitable method for determining a distance which provides for continuous determination of the distance—which can therefore also be made discrete—and in addition is easy to handle and provides for a large variety of applications. The distance measuring device comprises analytical electronics and a sensor facility, which comprises at least one coupling probe for feeding an emitted signal into a conducting structure with reflection body. Moreover, the conducting structure comprises a feeding block with a feeding area connecting an HF transceiver via a wave guide with dielectric support system to the coupling probe.

Abstract: A distance measuring device is capable of measuring a distance to a piston with a cylinder both discretely and continuously. The distance measuring device includes a coupling probe located axially symmetrically with respect to a piston rod within the cylinder. The coupling probe transmits a continuous wave electromagnetic signal into the cylinder and detects its reflection to measure the distance to the piston while the piston is moving.

Abstract: Described is a distance-measuring device and a method for determining a distance, which uses a sensor in the form of a cavity resonator to continuously perform a distance determination and allows diverse possible uses.

Abstract: The invention relates to a radar distance measuring device. An especially linear frequency-modulated high frequency signal is emitted via an antenna and mixed with an echo signal reflected by a target object whose distance is to be determined. The distance of said target object can then be calculated by analyzing the frequency of the mix result. The aim of the invention is to improve the distance resolution or increase the accuracy of measurement. To this end, a first frequency analysis is first carried out to obtain a rough analysis result. Said rough analysis result is used to control a filtering device which then restricts the mix result in its time range to a segment around the frequency of the target object. A discrete Fourier transformation is then carried out for this segment in order to produce an analysis result with a more refined scanning step than the first frequency analysis.
