摘要： An electromagnetic, compensating force-measuring or weighing device having at least one working coil movable in an air gap of a magnet system. At least two members for temperature compensation are positioned at different, spaced apart points. The compensating effect of these members on the active part of the system jointly produce a temperature compensating value which is optionally approximately equal to the exact value of the actual temperature curve. The members may be in the form of a plurality of minute particles of nonretentive material having a high negative coefficient of saturation magnetization distributed in the active part. The members may be formed of the afore-mentioned material and be positioned on the active part or be PTC or NTC resistors so positioned.

摘要： In a parallel rod guide for electronic balances having a measured value sensor, typically corner load adjustments are made by adjusting the parallelism of the two rods and such adjustments are normally sufficient. However, this can eliminate only linearly load-dependent corner load errors. In order to eliminate corner load errors which are non-linearly dependent on the load, the present invention provides an adjustment assembly which varies the resilience of the fastening points on the system carrier side of at least one rod to horizontal forces. The adjustment assembly may comprise, a screw/nut connection whose position can be varied vertically therewith, varying the effective length of a resilient intermediate part.

摘要： A parallel construction, particularly for a top-loading balance with elecmagnetic force compensation, has two essentially identical, preferably trapezoidal, movable guides in parallel horizontal planes. The guides are mounted permanently at one end and connected together by a movable rigid connecting element at the other end. The two guides are displaced relative to one another in their planes at right angles to their axis of rotation.

摘要： An electronic balance with a weighing scale which is connected via a parallel guide to a system carrier, and with a translation lever which is rotatably mounted on the system carrier and onto the shorter lever arm of which the force of the weight acting on the balance scale is transferred via a coupling element and on the longer arm of which the coil of an electromagnetic compensation of force is fastened, that at least one spring touches the translation lever for the purpose of astatization, the line of application of which spring passes through the point of rotation of the translation lever. This results in a compact design and a good efficiency of astatization. It is advantageous to use a wire or a band and/or a laterally jutting-out projection on the translation lever as spring.

摘要： An electronic balance with scale on top and with parallel guide rods whereby corner-load errors can be corrected by means of the inclusion of at least one leaf spring which is fastened to a load receiver and is supported on the other end on a fixed point of the housing. The magnitude of the correction can be adapted to the corner-load error of the unadjusted parallel guide by means of the selection of the spring stiffness of the leaf spring and/or by means of its effective length.

摘要： In an electronic balance with a scale on top with two guide rods which connect a load receiver to a system carrier fixed to the housing as parallel guide, with at least one translation lever which is connected to the system carrier by means of two springs and with a coupling element (9) which transfers the force corresponding to the mass of the weighed material from the load receiver to the shorter lever arm of the translation lever while the counteracting force imposes on the longer lever arm of the translation lever. The two springs and the coupling element (9) are connected to each other by a common cross piece (8) and consist of a single sheet of metal, whereby the thickness of the sheet of metal is greater than the shorter lever arm of the translation lever and the material thickness is reduced in such a manner both in the area of the two springs and in the area of the coupling element (9) that the shorter lever arm is formed by an offset of the thin area (26) of the coupling element (9) produced in the longitudinal direction of the lever in relation to the thin areas (28) of the springs. The length of the shorter lever arm is determined only by the offset of the thin areas (26, 28) of the coupling element (9) and of the springs within the sheet thickness and can be very precisely manufactured by means of suitable manufacturing methods.

摘要： An electronic balance with a system carrier (1) fixed to the housing, a load receiver (2) with two guide rods (3/4) which function as parallel guide, connect the load receiver to the system carried in a vertically movable manner, with four protruding arms (5, 6) which are fastened to the load receiver (2) and carry supports points (7, 8, 9, 10) for a balance scale on their ends and with a low-travel measured value receiver (14, 15) which is loaded either directly by the force of weight acting on the balance scale or with the interpositioning of a translation lever (11). The protruding arms (5, 6) comprise a central recess (19, 20) in front of their ends (17, 18) so that an upper web (21, 23) and a lower web (22, 24) remain and form a parallel guide for the particular support point (7, 8, 9, 10) of the balance scale. Each of the four support points (7, 8, 9, 10) of the balance scale is associated with a wire strain gauge (27, 28, 29, 30) located on one of the associated webs (21, 23). These four or eight wire strain gauges (27, 28, 29, 30) are arranged in such a manner on the webs (21, 23) that they are all expanded, stressed upon an approximately central loading of the balance scale. These four wire strain gauges (27, 28, 29, 30) are wired to two half bridges and the output signals of the two half bridges are added with presettable values to the output signal of the measured value receiver (14, 15).
