oberschalige electronic balance with two übersetzungshebeln

摘要

The balance has a parallel guided force input element (2), two conversion levers (9,11) and two force transfer elements (8,10), whereby the load input element, parallel guide linkages (3,4), conversion levers and force transfer elements are made in one piece from a metal block. A coil (12) mounted on the long lever arm of the second conversion lever (11) lies in the magnetic field of a permanent magnet (13) attached to the housing. Both conversion levers are angled levers and the second force transfer element (10) transfers horizontal forces. A vertical, plate-shaped thin point (7) is provided between the load input element and the first force transfer element.
