    Abstract: 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.

    Abstract: 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.

    Abstract: The invention is a field device with an input unit comprising a first number of switch elements in order to generate first input signals and a second number of magnetically actuatable sensor elements assigned to the switch elements in order to generate second input signals which are OR-linked to the first input signals. Each switch element is assigned to at least two sensor elements, which are arranged and connected such that the respective second input signal is output only when at least two specified sensor elements assigned to a switch element are activated.
