Abstract: A microwave measuring device having a transmitting module and a receiving module and an apparatus having these modules are described. The two modules are accommodated either in a common housing or in separate housings. The transmitting module can be coupled to a transmitting antenna and the receiving module can be coupled to a receiving antenna. In order to compensate for measurement errors, in particular temperature-related measurement errors, at least one RF bypass cable runs outside the housing/the housings and can be used to couple the transmitting module and the receiving module while bridging the measuring section defined by the two antennas.

Abstract: A device for measuring at least one of dielectric and magnetic properties of a sample by means of a microwave transmission measurement includes a transmitting antenna and a receiving antenna defining a transmission measuring section in which the sample to be measured is located, and transmitting and receiving modules. The transmitting and receiving modules include one or more transmission-side and receiving side synthesizers, a clock, one or more transmission side or receiving side mixers to generate intermediate-frequency signals based on high-frequency signals received from the synthesizers, and at least one evaluation unit to perform an evaluation based on the intermediate-frequency signals.

Abstract: A device for measuring the dielectric and/or magnetic properties of a sample by means of a microwave transmission measurement, comprising a transmitting antenna and a receiving antenna that define a transmission measuring section in which the sample to be measured can be positioned, at least one transmission-side synthesizer for generating a high-frequency signal with a frequency between 800 MHz and 30 GHz, a frequency standard that is connected via a transmission-side low-frequency synchronization signal line to the transmission-side synthesizer and to which the transmission-side synthesizer is coupled phase-locked reproducible, as well as an evaluation unit which is connected at least indirectly to the transmission-side synthesizer and the receiving antenna.

Abstract: A device for realizing an online element analysis for a substance (S) that is conveyed past or flows past a measuring station is provided with a device for conveying the substance to be measured, a measuring station with an X-ray source (10), and an X-ray fluorescence detector (20) with radiation inlet. To improve the tolerance to calibration errors and a changing height of the sample surface, at least one first X-ray conductor (30) extends from the radiation inlet of the X-ray fluorescence detector in the direction of the conveying device (51).
