Abstract: A method of determining a load measurement value in dynamic weighing of an object passing over a weighing platform supported by load-sensing means generating a load-dependent weighing signal (S) which rises from a basic level to a peak level, to subsequently fall to the basic level. An at least approximative signal peak value (S.sub.peak) is determined as representing the weighed load. The weighing signal is integrated at least during a time interval (t.sub.1 -t.sub.5) about the point where the signal peak value is determined in order to produce a summation result, the time interval being recorded as a measurement time factor (M). Further, a form factor (F) for the weighing signal is calculated in the form of the ratio of the summation result, i.e., the integrated area under the weighing signal (S) for the time interval (t.sub.1 -t.sub.5), to a corresponding rectangular area that would be obtained in static weighing, i.e., the product of a peak value and the above time interval. Finally, the load measurement value is determined as the above-signal peak value with a resolution depending on a quality factor Q=F.multidot.M.multidot.k, wherein k is a factor chosen while taking into consideration the weighing conditions.

Abstract: A load-sensing body for weighing machines and the like, comprising two circular plates (1, 2) and an intermediate space (15) communicating with a pressure-sensing member, an O ring-type seal being arranged between the plate circumferences, and one plate being provided with at least two open grooves (11, 12) in the opposing plate sides, the grooves being arranged at a slight radial distance from one another and facilitating axial displacement of a central plate portion disposed inside the grooves upon axial compression of the plates.Elastically yieldable portions are arranged in the load-sensing body to act between the body and loading and/or load-receiving elements for the purpose of allowing initial compression of the plates to prevent for an initial compression of the seal and subsequently allow direct load transmission to the load-sensing body.
