A radar fill level measurement device includes a radar sensor unit which has comprising a radar antenna emitting a measurement signal towards a filling material surface. The radar fill level measurement device in addition includes a limit level sensor unit determining a fill level of the filling material. The limit level sensor unit detects when the spacing between the filling material surface and the radar antenna falls below a minimum spacing. A radar antenna arrangement is for a radar fill level measurement device. The radar antenna arrangement includes a radar antenna horn which has a housing and/or a cover, and a limit level sensor unit. At least part of the limit level sensor unit is arranged on the housing or on the cover or is integrated therein.

Topology determination of a filling material surface with uniform line scanning

For determining the topology of a bulk material surface, a series of echo curves are detected in different primary radiation directions of the antenna. In the process, the primary radiation direction of the antenna is changed in such a way that all of the generated echo curves of the series of echo curves can be used for determining the topology of the bulk material surface. As a result, the measurement time can be reduced.

A measurement device is provided for determining a distance of the measurement device from a medium and a flow speed of a medium by evaluating a transmission signal emitted by the fill level measurement device and reflected by the medium. The measurement device includes an antenna arrangement for emitting the transmission signal in two different directions. The flow speed of the medium can be determined using the Doppler shift of the transmission signal.

Determining a level and flow speed of a medium

A fill level measurement device is specified for determining distance of the measurement device and flow speed of a medium, which comprises a frequency-modulated transmission signal having a rising and a falling frequency ramp. The flow speed of the medium can be determined by the Doppler effect arising from the flow speed of the medium.

Determining a distance and a flow speed of a medium

For determining the topology of a bulk material surface, a series of echo curves are detected in different primary radiation directions of the antenna. Subsequently, for each distance cell of the echo curves, the maximum of all of the echo curves is determined and the distance thereof is plotted as a function of the coordinates thereof so as to obtain an image of the topology of the bulk material surface in two or three dimensions.

The invention relates to a capacitive pressure transducer for measuring the pressure of a medium adjacent to the pressure transducer, which has a resilient measuring diaphragm, of which the first side is at least partially in contact with the medium and of which the second side, which faces away from the medium, comprises a measuring electrode and, for measuring a temperature, a resistance element made of a material having a temperature dependent resistance. Furthermore, the pressure transducer has a base body, which is arranged to oppose the second side of the measuring diaphragm, with a counter electrode, which forms a measuring capacitance with the measuring electrode. According to the invention, the resistance element is formed as a resistive layer disposed between the second side of the measuring diaphragm and the measuring electrode.
