Abstract (en)

[origin: WO2018145858A1] The present invention relates to a method for monitoring the condition of a vibronic sensor (1) for determining and/or monitoring at least one process variable of a medium (2) in a container (2a) using at least one sensor unit (3) with a mechanically vibratory unit (4), comprising the following method steps of: determining a measured value for at least one physical and/or chemical variable (f, f0) characteristic of the vibronic sensor (1) while the sensor (1) is at/in the place of use thereof, comparing the measured value of the physical and/or chemical variable (f, f0) with a reference value for this variable (fref, f0,ref), and determining a condition indicator from the comparison.
