Apparatus and method for the weighing of the optionally nsta ends to a harmonic motion

摘要

described is a device and a method for determining the mass of an object by shifting the schwingungsdauer the vibration of a flexible walled ablegetisches (40). an object whose mass is to be determined, is placed on the ablegetisch, which, in turn, to a vibration is suggested. the schwingungsdauer harmonious movement is measured.the schwingungsdauer with the schwingungsdauer harmonious movement, compared with the no object on the ablegetisch is located, and the difference and the shift of the frequency allows the determination of the mass of the object.the ablegetisch is a range of flexible elements (30) supported the parallelogrammartigen building), the biegebelastungen eliminated.
