A weighing sensor is provided for an electronic balance. A weighing unit of the weighing sensor has a load-receiving portion, a fixing portion, and parallel guiding members that connect the load-receiving and fixing portions A lever, with a first end connected to the load-receiving portion, is located between the parallel guiding members and the fixing portion. A lower portion of a photoelectric position limiting block is connected to the fixing portion, and an upper portion thereof has a limiting structure. A tail end portion of a second end of the lever is disposed in the limiting structure, limiting its deviation. The photoelectric position limiting block has a photoelectric position sensor and a stop structure for limiting deviation of the tail end portion.

An article inspection apparatus includes a measuring unit 11 that outputs a measuring signal of weight within a required measurement time from a weight application time, when the weight of an article W is applied, a determination unit 16 that inspects the article W based on the measuring signal, an electromagnetic coil 84 that applies a diagnostic load to the measuring unit 11, and a performance diagnosis unit 18 that causes the diagnostic load to be applied from the electromagnetic coil 84 to the measuring unit 11, within a predetermined diagnosable time longer than the required measurement time from the weight application time, when the weight of the article W is applied to the measuring unit 11, and diagnoses the performance of the measuring unit 11, based on the measuring signal when the diagnostic load is applied.

A magnetic bearing assembly (20) comprises a first magnet assembly (34) for generating a first quadrupole magnetic field in a first plane and a second magnet assembly (36) for generating a second quadrupole magnetic field in a second plane. The second plane is arranged parallel to the first plane. The quadrupole magnetic fields exhibit in each case in the planes magnetic field axes arranged at an angle to one another between four poles. A longitudinal axis (A) is defined at right angles hereto by the centres of the quadrupole magnetic fields. At least one diamagnetic element (44) is arranged on the longitudinal axis (A). The first and second magnet assemblies (34, 36) are arranged relative to one another in such a way that the first and the second quadrupole magnetic fields are rotated towards one another about the longitudinal axis (A) by an angular amount which is not a whole-number multiple of 90. Such a bearing arrangement can be used in particular in a magnetic levitation assembly (10) with a lifting assembly (26).

The disclosure relates to a scale operating according to the principle of electrodynamic force compensation and to a method for its operation. An automatic switchover from a measuring mode to an overload mode is provided for detecting overload forces. In this overload mode the load resistance formed by a coil and at least one measuring resistor is reduced in order to allow a higher coil current at the same output stage power.
