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： 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： It is necessary, when high requirements are demanded from balances, that the effect of different disturbance variables such as, e.g., temperature and/or moisture on the measuring system be corrected. To this end, temperature and moisture sensors are used from whose output signal correction values are calculated. The invention suggests that a storage area be provided into which the instantaneous measured results of these sensors are stored in succession, where they remain stored for a set time. This data stemming from different times, evaluated with set weighting factors, could then be used to calculate the corrections. This makes it possible to obtain a good correction of changing disturbances even with a different behavior in time of sensors and measuring system.

摘要： An electronic balance including a housing (1), a weighing scale (2), a windshield (3), which preferably at least partially surrounds the weighing scale, and a display and operating unit (4) which is connected to the balance housing. The connecting part (5) between the display and operating unit (4) and the housing (1) consists essentially of a material with poor heat conduction properties. At least one vertical radiation protection plate (6) is provided between the display and operating unit (4) and the housing (1), and the connecting part (5) is configured in such a way as to impair air convection on both sides of the radiation protection plate(s) (6) preferably to the least extent possible. This results in excellent thermal decoupling between the display and operating unit (4) and the housing (1).

摘要： An analytical balance that includes a balance scale, a wind guard encircling the balance scale, and an apparatus for generating an ionized stream of air for dissipating electrostatic charges of goods to be weighed. The apparatus for generating an ionized stream of air includes a blower that draws in air from the weighing space into at least one boundary surface of the weighing space. The blower also recycles the air back into the weighing space via at least one exhaust opening at another point. In this manner, highly effective dissipation of electrostatic charges is possible, and the stream of air can be conducted so that it exerts scarcely any vertical forces on the goods to be weighed. The analytical balance is very user-friendly in operation. Additionally, the apparatus for generating an ionized stream of air is preferably structured to be an easily installed optional component of the analytical balance.
