MEASURING SENSOR OF THE VIBRATION TYPE

摘要

The measuring sensor comprises: at least two sensor tubes (4, 5), mounted such as to be able to oscillate and at least partly vibrating when in operation, of which at least one sensor tube (4, 5), serving for the passage of at least a partial volume of the medium for measurement, communicates with the pipeline and at least one transducer element for the conversion of electrical energy into mechanical energy and/or vice versa. Both sensor tubes (4, 5) are mechanically coupled together by means of at least one coupling element on the inlet side and at least one coupling element on the outlet side such that both the inlet-side coupling elements and the outlet side coupling elements are subjected to repeated deformation during operation corresponding to vibrations of at least one of both sensor tubes (4, 5). The transducer element, in particular formed by a piezoelectric deformation body and at least one of the coupling elements are at least indirectly coupled for the conversion of electrical energy into mechanical vibrational energy or vice versa, such that the transducer element carries out at least proportional vibrational movements which correspond to the repeated deformations of at least one of said coupling elements.
