摘要： Disclosed is a balance with a first parallel guide (3, 3') which resiliently connector a load receiver (2) to an area (5, 5') fixed to the housing and which is resiliently deformed under the influence of the weight to be measured, and with a second, softer parallel guide (8) which is connected by its one end to the load receiver (2) and by its other (11) end via a force receiver which is at least approximately without displacement to the area (5, 5') fixed to the housing and which transfers as a result thereof a fraction of the force of the weight onto the force measuring receiver that both parallel guides (3, 3', 8) exhibit at least approximately the same height and the same length and are arranged close to one another laterally. The second parallel guide is advantageously locate between two partial areas (3, 5, and 3', 5') of the first parallel guide.

摘要： It is suggested for a balance with one or several weighing cells (1-4, 31) with a total of at least eight wire strain gauges (D.sub.1 -D.sub.4, S.sub.1 -S.sub.4), four of which (D.sub.1 -D.sub.4) are expanded under load and four (S.sub.1 -S.sub.4) compressed under load, in which the eight wire strain gauges are connected together circularly in series so as to form a single Wheatstone bridge which is supplied with voltage along a diagonal (12, 13) (vertical diagonal) and the output signal is taken off along the other diagonal (14, 15) (horizontal diagonal) that a signal is additionally tapped off along the upper horizontal chord (16, 17) and along the lower horizontal chord (18, 19). This makes possible a corner-load adjustment for the balance utilizing the additional signals.

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： 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.
摘要翻译：当需要来自平衡的高要求时，有必要校正不同干扰变量（例如温度和/或水分）对测量系统的影响。为此，使用从其输出信号校正值计算出的温度和湿度传感器。本发明提出一种存储区域，其中这些传感器的瞬时测量结果被连续存储在该存储区域中，在那里它们保持存储一段设定的时间。然后可以使用由不同时间产生的数据，用设定的加权因子进行评估，以计算校正值。这使得即使在传感器和测量系统的时间上具有不同的行为，也可以获得改变的干扰的良好校正。

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.
