Abstract
A measuring transducer has a vibration element, an electromechanical oscillation exciter, and a sensor for registering mechanical oscillations at a first measuring point and providing oscillation signal representing movements of the vibration element, and a housing for the measuring transducer. The oscillation exciter, the first oscillation sensor and the vibration element are arranged within the housing. The method includes positioning a (test-) magnetic for producing a (test-) magnetic field causing vibration for producing a test signal, using the test signal for ascertaining a characterizing number value, which quantifies an oscillation characterizing number, and comparing the characterizing number value with threshold values for the oscillation characterizing number to detect a disturbance of the measuring system, when the characterizing number value exceeds a corresponding threshold value, or has left a value range bounded by the threshold value.
