Abstract
A method for carrying out operating tests of vibration level switches for liquids or solid bulk material or mixtures thereof is provided, whereby a vibration resonator () of a level detection sensor is excited by an oscillation exciting feedback circuit to oscillate, whereby at least one excitation parameter of a plurality of signal processing blocks () of the feedback circuit is varied, and the resulting oscillation change is compared by a microprocessor () to datasets comprising data of corresponding oscillation changes of a failure free system. Moreover, a vibration level switch for measuring the level in containers for carrying out the inventive method is provided.
