    摘要: A geomagnetic field measurement device has a three-dimensional magnetic sensor and a storage device that stores plural pieces of magnetic data sequentially output from the three-dimensional magnetic sensor. The geomagnetic field measurement device calculates, based on the pieces of magnetic data, a distortion estimation value indicating a degree of difference in shape between a three-dimensional figure defined so that the plural sets of coordinates indicated respectively by the plural pieces of magnetic data are distributed adjacent to a surface thereof and a spherical surface, and determines whether there is distortion in the shape of the three-dimensional figure based on the distortion estimation value, to update an offset for correcting each of the plural pieces of the magnetic data in a case in which it is determined that there is no distortion.

    摘要: The invention relates to a method for measuring at least one of the parameters of torsion angle, change in length, or magnetic field. To this end, a dynamic magnetization is generated according to the invention in a first conductor segment (AB) of a magnetizable or magnetized electrically conductive conductor arrangement (AD) by applying a magnetic field and applying a current impulse to the first conductor segment (AB). A magnetization is thus induced and migrates from the first conductor segment (AB) into a second conductor segment (CD) comprising a helical anisotropy (α). The anisotropy (α) allows the magnetization thus transported to be captured by means of a voltage generated across the second conductor segment due to the transport of the magnetization (9), said magnetization being a dimension for the parameter of torsion angle, change in length, magnetic field, or a mixture of a plurality of said parameters. During the measurement, at least one conductor segment (AB; AD) of the conductor arrangement is exposed to a magnetic field having a modified magnetic field strength, and the dynamic magnetization is determined at at least two different magnetic field strengths of the modifiable magnetic field. The voltages (9) thus obtained and detected at the different magnetic field strengths are used together for forming the dimension for the parameter of the torsion angle, the change in length, and/or the magnetic field. The method is suitable for producing sensors.

    摘要: A magnetometer includes at least one sensor (10) for sensing a magnetic field component, a biasing circuit (6), and a processor (1). The sensor (10) generates an output signal having a signal characteristic that varies in response to the sensed magnetic field component and in response to an applied bias. The biasing circuit (6) dynamically biases the sensor (10) in response to a bias setting signal. The processor (1) is coupled to receive the output signal from the sensor (10) and coupled to the biasing circuit (6). The processor (1) is operable to generate the bias setting signal (3) and thereby control the biasing circuit (6) to dynamically bias the sensor such that the signal characteristic of the output signal is maintained in a target range. The processor (1) determines the magnetic field component sensed by the sensor (10) as a function of the bias setting applied to the sensor.

    摘要: Eine Sonde zur Erfassung von magnetischen Wechselfeldern weist einen hochpermeablen Sondenkern (10) und eine diesen umgebenden Meßwicklung auf, die aus mehreren, in Reihe geschalteten Spulen zuammengesetzt ist. Zwecks Schaffung einer Sonde, die geeignet ist für die Erfassung extrem niederfrequenter, magnetischer Wechselfelder aus einer Mindestdistanz, die üblicherweise für die Detektion von solche Wechselfelder erzeugenden Schwimmkörpern gefordert wird, ist der Sondenkern (10) aus flachen Streifen (16) aus amorphem oder mikrokristallinem, magnetisierbarem Material mit dazwischenliegenden Isolationsstreifen (17) zusammengesetzt. Die Spulen der Meßwicklung sind als selbsttragende Spulen, vorzugsweise als Backlackdrahtspulen, ausgebildet und umschließen den Sondenkern (10) nahezu abstandslos.
