摘要： The invention relates to a Coriolis measuring sensor for detecting a mass flow rate or a density of a medium flowing through a measurement tube of the Coriolis measuring instrument. The measurement tube has an inlet and an outlet designed to convey the medium between the inlet and the outlet; an exciter; and two sensors; the measuring sensor comprising a supporting element having a chamber designed to house the measurement tube at least in portions. The magnet device comprises a magnetically conductive holder for magnets and a first pair of magnets arranged on the holder on a first face of the coil device, with the magnets designed to cause a magnetic field perpendicularly to a cross-sectional plane of the coil, and the magnetic field of a first magnet of the pair is oriented so as to be opposite to the magnetic field of a second magnet of the pair.

摘要： A sensor includes an oscillator having a measuring tube for a medium, an exciter array having two exciter assemblies, an inlet-side and an outlet-side sensor array, and a measuring and operating circuit for driving the exciter array and detecting the sensor arrays. A first of the exciter assemblies is secured to a measuring tube, and the measuring tube is intended to be excited to vibrate in relation to a second of the exciter assemblies. A center of gravity of the first exciter assembly lies in a measuring tube transverse plane in relation to which the measuring tube runs mirror-symmetrically. The exciter array comprises an electrodynamic exciter and a compensating mass, where the electrodynamic exciter is designed to exert an exciter force, which acts between the first and the second exciter assembly, on the measuring tube. The effective center of the exciter force is located outside the measuring tube transverse plane.
