Abstract: A field device for measuring the filling level, the pressure or the density of a medium in a container is described. The field device comprises two processors that are separate from each other. The first processor corresponds to a lower safety standard while the second processor corresponds to a higher safety standard. Functions of the field device that are directed towards safety are carried out in the second processor. Functions that are less critical to safety are carried out in the first processor. Data exchange between the two processors is controlled by way of an operating system.

The analysis method is at least one analysis method selected from the group of analysis methods comprising analysing the echo curve by means of at least two parallel tasks, and analysing the echo curve by comparing the echo curve with a spurious-echo curve at the IF-level.

Abstract: A level or density of a medium in a tank is radiometrically measured by detecting the light flashes generated by a scintillator with an array of photodiodes. Corresponding voltage pulses are summed up and analyzed with respect to their relevance before they are used for determining the level or the density of the medium.

Abstract: The invention relates to an electrical or electronic level indicator which is positioned in a plug-in housing 24. The plug-in housing 24 is closed with a cover 10. This cover 10 is furnished with a handle bar 11, which serves as an aid for removing the cover 10. Positioned inside the cover 10 are rotating cylindrical pins 12, 13 which allow the potentiometers 32 and/or switches 33 to be adjusted. The electrical components 32, 33 are positioned on a circuit board 30, which lies inside the cover 10.

Abstract: Both in potential separation in the microwave path, and in potential separation directly between the two-wire loop and the output circuit, the quality of signal transmission may be negatively affected. A filling level radar device with potential separation within the electronics unit is stated, wherein potential separation does not separate analogue signals but instead separates digital signals or direct-current-free alternating signals. For example, the separation line leads through digital signal connections or alternating-voltage signal connections. As a result of this the expenditure for potential separation may be reduced and the transmission quality may be improved.
