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： 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： 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： In a drying balance with scale on top and with a radiation source for heating and drying material to be weighed located on the balance scale, the radiation source (11) is permanently located behind the balance scale (5) and a bent cover (7) which functions as a radiation deflector is movably located over the balance scale (5). This makes the construction lower and a moving of the radiation source (11) with its electric connections is avoided when the balance scale (5) is loaded. Moreover, differently constructed inner surfaces (7') of the cover (17) permit the drying balance to easily adapt to different radiation sources (11) and to different drying tasks.

摘要： In an analytical balance with scale on top with a scale carrier which is directly operatively connected to the measured value receiver, with a balance scale disk (6) which rests in a removable manner on the scale carrier, with a weighing chamber which surrounds the balance scale disk (6), the scale carrier and the measured value receiver, with a weighing chamber lock which constitutes the communication between the weighing chamber and the environment and which consists of two sets of closing doors or elements located in a vertically displaced manner in the form of a lock and with a transport device which can move the balance scale between a weighing position on the scale carrier and a loading position outside of the weighing position on the scale carrier and a loading position outside of the weighing chamber, the two closing elements of the weighing chamber lock are located above one another. The lower closing element consists of at least one level, horizontal plate which can be shifted in the plate plane. The upper closing element consists of at least one level plate or of a cylindrically bent plate which can be shifted in the plate plane or in the cylinder surface. The transport device for the balance scale disk moves the latter essentially vertically.
