Abstract: A drying balance is disclosed with a means (11) for supplying energy for the drying of material to be weighed located on the balance scale (6,16) and with a digital evaluating unit (23,24,25) for calculating the moisture content from the measured weight loss of the specimen and for determining the end point of the drying in which balance the digital evaluating unit (23,24,25) calculates the inflection point from the chronological course of the weight loss and derives the criterion for determining the final point therefrom. The criterion for the final point consists in that the slope of the drying curve drops below a certain value which is derived from the coordinates or the slope of the drying curve at the inflection point.

Then, the output signal of the temperature sensor (8) is multiplied by this correction factor during dryings in order to obtain the true temperature of the substance.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: In an electromagnetic balance based on the principle of the eletromagnetic compensation of force a weight-proportional counterforce is generated by a current-carrying coil in a permanent magnet system. An arrangement with annular coil with vertical axis and with a permanent magnetic system constructed symmetrically to the central plane of the coil has proven to be advantageous. However, this arrangement results in a relatively great construction height of the balance. In order to decrease this height, the invention suggests that the soft iron pole plate which is usually present between the like poles of the plates of active magnetic material be reduced in its diameter or entirely eliminated and that the coil be allowed to extend into this area between the plates of active magnetic material. This in conjunction with the use of materials having high coercivity makes a very low constructional height possible.
