摘要： An apparatus including one or more sensor units. Each of the sensor units includes an inner shell, an outer shell, and a magnetic sensor array. The magnetic sensor array is disposed between the inner shell and the outer shell. The inner shell, the outer shell, and the magnetic sensor array have curved shapes that complements an outer surface of a pipe. The magnetic sensor array may comprise a plurality of printed circuit board strips. Each of the plurality of printed circuit board strips comprise a plurality of magnetic sensors distributed along each of the plurality of the printed circuit board strips.

摘要： Here is described an apparatus for measuring and/or monitoring a strength of a magnetic field inside a sample including: a fixing unit made of a non-magnetic material; a magnetic field strength measuring device having a sensor; and a first elongated member and a second elongated member. The elongated members are made of a material having a high relative magnetic permeability, and each of the elongated members has a first end portion and a second end portion. The fixing unit is configured to support the elongated members in a fixed posture such that the first end portion of the first elongated member and the first end portion of the second elongated member are positioned opposite to each other to form a gap, and the fixing unit is configured to support the sensor of the measuring device inside the gap or substantially inside the gap.
