摘要： The invention discloses an electronic balance with a scale on top, a balance scale, a balance scale carrier, two identical guide rods (7,8) which connect in an articulated manner the balance scale carrier and the balance scale in the form of a parallel guide to a system carrier (1/5) fixed to the housing and with at least one corner-load adjustment lever (22') which is connected to the system carrier via a thin area (24) and which carries a support point in the vicinity of this thin area (24) for the end of a guide rod (7) on the system carrier that the corner-load adjustment lever (22') is bent at right angles between the support point of the guide rod (7) and the thin area (24) to the system carrier (1,5) in such a manner that the moving joint (17) of the guide rod (7) and this thin area (24) are at the same height. As a result, even great forces in the guide rods such as those which occur at an off-center loading of the balance scale do not cause any torque on the corner-load adjustment lever and thus result in a very stable corner-load adjustment.
摘要翻译：本发明公开了一种电子天平，其具有在顶部的秤，平衡秤，平衡秤托架，两个相同的导向杆（7,8），其以铰接方式连接平衡秤托架和平衡形式的平衡秤引导到固定到壳体的系统载体（1/5）和至少一个角载荷调节杆（22'），所述角载荷调节杆（22'）经由薄区域（24）连接到系统载体，并且在在该系统载体上的导杆（7）端部的该薄区域（24）附近，角载荷调节杆（22'）在导杆（7）的支撑点与以使得导杆（7）的移动接头（17）和该薄区域（24）处于相同高度的方式将薄区域（24）连接到系统托架（1,5）。因此，在导向杆（例如在平衡秤的偏心加载时发生的那些导向杆）中的大的力也不会在拐角负载调节杆上产生任何扭矩，从而导致非常稳定的转角负载调节。

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： There is disclosed a balance based on the principle of the electromagnetic compensation of force with a cylindrical permanent magnet system, with a magnet cover and with a coil for generating the counteracting force that an emitter and a receiver of the optical position sensor be housed inside the magnet cover. The slit diaphragm of the optical position sensor, which extends from below into the area between emitter and receiver, then forms a compact unit with a carrier, e.g., the end of a translation lever, and with a coil and mutual shifts at temperature changes and temperature gradients occur only to a minimal extent.

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： 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.
