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.

A soft magnetic sensor comprising a soft material containing randomly distributed magnetic microparticles and a magnetometer that can estimate force and localize contact over a continuous area. A reference magnetometer can be used to filter motion and ambient noise. Methods for locating contact and determining force comprise data analysis of the magnetometer output. In some embodiments, the sensor can localize an object prior to contact.

A magnetic field sensor array includes a plurality of sensor segments, each including a plurality of magnetic field sensors. A magnetizing current conductor is situated so as to run in the area of the magnetic field sensors in such a way that elements of the magnetic field sensors may be magnetized. A plurality of parallel-connected half-bridges, each including a high switch p.sub.J and a low switch n.sub.J, each include a center tap connection situated between the switches. The magnetizing current conductor is connected to each center tap connection, by means of which the magnetizing current conductor is divided into separately activatable magnetizing segments. Elements of a sensor segment are magnetized in that two switches n.sub.J and p.sub.J+1 having different electrical potentials, or alternatively p.sub.J and n.sub.J+1, of two directly adjacent half-bridges are closed simultaneously. At least one further switch n.sub.X<J or p.sub.Y>J+1 or alternatively p.sub.X<J or n.sub.Y>J+1 is closed.
