摘要： 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).

摘要： A force-transmitting mechanism (110) has stationary and load-receiving portions (111, 112). The load-receiving portion is joined to a measurement transducer on the stationary portion through a force-transmitting connection, directly or through at least one coupling element (119) and at least one lever (116). The force-transmitting mechanism has a parallel-guided coupling means (124), a calibration lever (120) with a fulcrum on the stationary portion, and calibration lever arms (121, 122), one of which is rigidly connected to a calibration weight (123). The parallel-guided coupling means (124) is arranged between the second calibration lever arm and the at least one coupling element or an arm (117, 118) of the lever. The parallel-guided coupling means is divided into fixed and parallel-guided coupling parts (126, 125), which allows a force to be transmitted between the coupling parts. Parallel elements of the parallel-guided coupling part absorb relative traverse displacements from transmitted forces.

摘要： A weighing cell based on the principle of electromagnetic force compensation and having an optoelectronic position sensor that includes a light source, a light receiver, and a shutter vane. The light receiver functions to generate a position sensor signal corresponding to a deflection of the shutter vane from a zero position which occurs as a result of placing a load onto a load receiver of the weighing cell. A controller functions to regulate compensation current in response to the position sensor signal in such a way that the shutter vane and the movable parts of the weighing cell connected to the shutter vane are returned to the zero position by the electromagnetic force between a coil and permanent magnet system of the weighing cell.

摘要： A novel electromagnetic balance-type weighing apparatus according to the invention includes a weighing pan/balance beam assembly (15) whose balance beam is angularly displaced as a function of the weight of an object of weighing placed on the weighing pan. An electromagnetic coil (9) is provided to generate an electromagnetic force that offsets the displacement of the balance beam of the weighing pan/balance beam assembly (15) caused by the weight of the object of weighing. A displacement detector (3, 4, 5) is provided to detect the displacement of the balance beam of the weighing pan/balance beam assembly (15). An operation unit (7) performs operations to determine a control voltage in response to the detection signal transmitted from the displacement detector (3, 4, 5). A current transducer circuit (20) generates an electric current in response to the control voltage applied to it by the operation unit (7) and supplies it to the electromagnetic coil (9). The current transducer circuit (20) comprises a negative feedback loop circuit for feeding the output current from said current transducer circuit (20) back to the input terminal of the current transducer circuit (20). A weight calculator (24) calculates the weight of the object of weighing from the output current of the current transducer circuit (20).

摘要： An improved weighing apparatus of the electromagnetic load compensation type is disclosed, characterized by the provision of a stationary permanent magnet system including two oppositely arranged pairs of spaced parallel flat magnet members that cooperate to define a common air gap. The compensation current coil, which is connected for movement with the movable load-receiving member, is of a flat annular configuration and is contained in the plane of the air gap extending between the magnet members of each pair. The magnet members of one pair are magnetized oppositely from those of the other pair, whereby the magnetic field established across the portion of the air gap between the permanent magnet members of one pair is of a direction opposite that established between the permanent magnet members of the other pair. Consequently, not only can the compensation current for a desired compensation force effect be reduced, but also, the manufacture of the permanent magnet system is greatly simplified.
