The relates to a measuring device neck of a radar based, fill level measuring device for determining a fill level profile (L(α,β)) of a fill substance. In the measuring device neck, the waveguides for contacting the antenna arrangement are aligned along a contour (k1, k2), which surrounds the device neck axis radially symmetrically and adjoins the measuring device neck. Such is advantageous, since the waveguides can be made together as a monolithic, basic body, which can be inserted easily into the measuring device neck. Furthermore, the arrangement of the waveguides in the measuring device neck favors the thermal management in the transmitting/receiving electronics of the fill level measuring device, since its thermally critical radar chips can be spaced maximally from one another.
A radiation protection container of a measuring system serves for radiometric density or fill level measurement. The radiation protection container is based on two base bodies connected to one another via a planar surface. The radiation waveguide extends for focused emission in a plane defined by the planar surface, wherein the radiation waveguide is formed by depressions in the base body surfaces. The radiation protection container comprises radiation absorption structures formed by depressions and complementary elevations in the base body surfaces lying on top of each other. An advantage is that refractory base bodies based on steel can be used and it is possible for the depressions and/or elevations to be realized using surface machining. The radiation absorption structures ensure that no radiation exits the radiation protection container laterally.

A radar-based fill-level measuring device that operates, for example, according to the FMCW principle or the pulse time-of-flight principle comprises a temperature sensor. Thus, the measurement rate at which the fill level is determined can be controlled according to the measured temperature in such a way that, at least above a defined limit temperature, the measurement rate is reduced as the temperature increases further. Furthermore, the measurement can be completely stopped if the measured temperature exceeds a predefined maximum temperature, in particular 150° C. The development of heat in the fill-level measuring device is counteracted by the reduction of the measurement rate. The measurement rate is thereby adaptively adjusted with respect to the ambient temperature such that, even at elevated ambient temperatures, which can occur in the case of cleaning processes, the fill-level measuring device remains at least conditionally fit for use.
The present disclosure relates to a method for optimizing a measurement rate of a field device in a measurement system. The measurement system includes at least one second field device in which a measurement variable of the field device is correlated with the measurement variable of the second field device. The method determines a respective specific correlation pattern between the first measurement variable and the second measurement variable based on a learning phase. This makes it possible to check the measured values from the second field device for the correlation pattern during normal measurement operation and to change the measurement rate of the field device during the corresponding time window. This makes it possible to increase the service life and/or availability in the process installation.

Measuring device for determining a dielectric constant comprising an electrically conductive arrangement electrically contacts two waveguides with one another
The invention relates to a measuring device for determining the dielectric value of a medium. The measuring device is based on two waveguides, each of which has a signal gate on one end. The waveguides are, in such case, so arranged that the signal gates lie opposite one another. Formed therebetween is a sample space for the medium, such that a high frequency signal, which is in-coupled into the first waveguide, is transmitted into the second waveguide via the second signal gate after passage through the medium. Since the transmitted fraction and the reflected fraction of the high frequency signal depend strongly on the dielectric value, such can, as a result, be measured with a high sensitivity and, depending on choice of the frequency band and dimensioning of the waveguides, over a large value range.
