摘要： The measuring system comprises a vibration-type measuring sensor, a sensor housing, a magnetic-field detector, and measuring-system electronics electrically coupled both to an oscillation exciter and to oscillation-sensing devices of the measuring sensor. The measuring sensor is inside the sensor housing and the magnetic-field detector is outside the sensor housing. The magnetic-field detector is designed to convert changes in the magnetic field into a magnetic-field signal having an amplitude dependent on a magnetic flux through the magnetic-field detector and/or on an area density of said magnetic flux. The measuring-system electronics are designed to determine, on the basis of oscillation measurement signals of the measuring sensor, the mass-flow-rate measurement values representing the mass flow rate and to at least qualitatively determine, on the basis of the magnetic-field signal, whether an external magnetic field is established inside the measuring sensor.

摘要： The Coriolis mass flowmeter comprises a measuring transducer having a vibration element, an exciter arrangement, and a sensor arrangement The flowmeter further includes an electronic transmitter circuit coupled with the exciter arrangement and the sensor arrangement. The transmitter circuit supplies power to the exciter arrangement to force mechanical oscillations having a wanted frequency. The sensor arrangement includes two electrodynamic oscillation sensors to convert oscillatory movements of the vibration element into an electrical signal having an alternating voltage having an amplitude dependent on the wanted frequency and on a magnetic flux of its oscillation sensor. The sensor arrangement includes a magnetic field detector adapted to convert changes of the magnetic field into a magnetic field signal having an amplitude dependent on a magnetic flux and/or an areal density of the magnetic flux. The transmitter circuit ascertains mass flow measured values and ascertains whether an external magnetic field is present.

摘要： In the method, a portion of the metal tube is placed in a lumen of a metal sleeve having a metal wall surrounding the lumen. The metal tube is placed in such a manner that an outer surface of the metal tube and an inner surface of the metal sleeve at least partially contact one another. The metal sleeve is affixed on the portion of the metal tube placed in its lumen for forming a metal tube, metal sleeve, composite system. The metal tube, metal sleeve, composite system, in turn, is placed in the passageway of the metal body in such a manner that an outer surface of the metal sleeve and an inner surface of the passageway at least partially contact one another, in order thereafter by plastically deforming at least the metal sleeve of the metal tube, metal sleeve, composite system placed in the passageway to form a force interlocking between the inner surface of the passageway and the outer surface of the metal sleeve. The so formed metal tube, metal sleeve, metal body composite system can serve as a component of a measuring transducer, respectively a vibronic measuring device formed therewith.
