摘要： There is provided a coercivity performance determination device for a coercivity distribution magnet that is capable of determining, in a short period of time, with precision, and at as low a testing cost as possible, whether or not each part of one coercivity distribution magnet has a coercivity that is equal to or greater than the required coercivity. A coercivity determining device of the present invention comprises: a substantially C-shaped magnetic body; excitation means that generates a magnetic flow in the magnetic body; and a flux meter that measures the residual magnetic flux of the coercivity distribution magnet. Protrusions are provided at corresponding positions on two opposing end faces of the magnetic body, and the coercivity distribution magnet is held between the two protrusions to form an annular magnetic circuit. An external magnetic field generation means is formed by magnetic regions caused by the protrusions and non-magnetic regions comprising the air in the periphery thereof. An external magnetic field that is generated when magnetism flows through the protrusions is adjusted in such a manner that a reverse magnetic field, which comprises the sum of the external magnetic field and the demagnetizing field of the coercivity distribution magnet, corresponds to the coercivity required of each part of the coercivity distribution magnet. The residual magnetic flux when this has acted as the reverse magnetic field is measured with the flux meter to determine coercivity performance.

摘要： An apparatus for determining the paramagnetic characteristics of substances such as oxygen includes a cuvette rotating in a magnetic field. The cuvette includes measuring chambers and reference chambers and an alternating voltage is induced in the measuring field coils by the rotation of the cuvette along the magnetic field. A base signal disturbing the measuring signal is also generated. This base signal is caused primarily by changes in the thickness of the material in the reference chambers and the measuring chambers and/or by material thickness changes of the cuvette. To eliminate this base signal, the cuvette includes a magnetic compensating device. This device is mounted at such a position that it generates a compensating magnetic field during its rotation through the magnetic field. This compensating field generates a compensating voltage which has the same amplitude as the base signal but has a signal waveform which is opposite in phase to the base signal.

摘要： The invention is directed to an apparatus for determining the proportion of substances having paramagnetic characteristics, such as oxygen, in a mixture of substances. The apparatus has a housing and the mixture of substances is passed along an arrangement of four magnetic field sources by a rotatable cuvette arrangement mounted in the housing. The apparatus is improved in that the effect of external disturbing influences on the penetration of the cuvette by the magnetic field is reduced and so that the measuring characteristics are independent of the position of the plurality of magnetic field generating units. For this purpose, the arrangement of the magnetic field sources is simply disposed at one side of the housing lying opposite to the rotating surface of the cuvette arrangement facing toward the drive shaft. The arrangement of magnetic field sources includes a carrier plate on which the magnetic field sources are accommodated and carry respective measuring field coils. The magnetic field sources face with their end faces toward the cuvette arrangement.

摘要： A magneto-mechanical sensor can be use for paramagnetic gas analysis, in which a test piece has a conductor loop is rotatably held by at least one suspension wire. In order to be able to produce the conductor loop, which is to be electrically connected to the at least one suspension wire, with little manual effort and use a small-sized, light-weight sensor, portions of the conductor loop are applied to the surface of the test piece using a metallization process.
