Abstract: 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.
