Abstract: A field device for process automation in industrial or private environments, comprising an electronic circuit for controlling the field device, wherein the electronic circuit includes a first, a second and a third circuit board. The first circuit board is connected to and attached to the second circuit board and/or to the third circuit board by way of an electrical connector, wherein the second circuit board is located above the third circuit board.

Abstract: A measuring device is provided. The measuring device includes a sensor unit configured to detect a measurement signal, upstream measuring device electronics that include a signal processing circuit and an input interface, and a power limitation circuit arranged to limit the power supplied by the external power supply at the input interface.

Abstract: A sensor is provided for generating an output signal for detecting a limit level of a medium, a filling level of the medium, and/or for differentiating between different media, the sensor including: a processor to process a measurement signal generated using the sensor; and a reference unit to generate a reference signal, the processor is further configured to perform temperature compensation using the reference signal, the processor and the reference unit each having a signal conversion unit to provide temperature-dependent signal conversion, the signal conversion units being thermally coupled to one another, and the temperature compensation includes compensating for temperature dependency of the signal conversion unit of the processor using a thermal coupling.
