The invention relates to an electrical circuit arrangement having at least one input for analogue measured values, having a device for processing the measured values, a device for data input and at least one output for control and display signals, the intention being to make operation of this kind of circuit arrangement for level limit-value detection simpler, more reliable and more convenient. This is achieved in that a first signal-processing device (4), which also functions as an analogue/digital converter and digitizes the measured values being input, is provided, in that data in digital form are read, via a control device (9), into a memory means (5) which is protected against mains failure, these data being stored therein and read out therefrom, in that data and measured values read in and out are in each place displayed by means of a display device (13; 13.1, 13.2) and in that a device (7) for digital measured-value and signal processing is provided for comparing data stored in the memory means (5) with measured values and is connected to a second signal-processing device (10) that generates control and display signals. It is furthermore proposed for the electrical circuit arrangement for level limit-value detection in containers with electrically conductive media to be used by means of a measuring electrode responding to the electrical conductivity of the medium, the measuring electrode (18.1, 18.2, ...18.n) being ... with one of the inputs or with ...
