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 ( 1 ) 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 ( 5, 6, 7, 8, 9, 10 ) of the feedback circuit is varied, and the resulting oscillation change is compared by a microprocessor ( 14 ) 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.
