ABSTRACT:
A weighing apparatus is disclosed in which the load carrier (3) is arranged immediately adjacent the console (1), whereby the length of the transmission arm (3b) between the load carrier and the measuring component is reduced to a minimum. The parallel guidance system for the vertically movable components is provided by upper and lower resilient guide members (11, 11') having parallel spaced first (11a) and second (11bb) guide arms connected at one end with the console and load carrier members, respectively, and freely suspended means (11c) connecting together the other ends of the arms, thereby to define a folded guide arrangement in which the temperature-dependent changes in lengths of the arms balance each other, whereby temperature-independent guidance is produced. Furthermore, by the use of a transmission member 3b of relatively short length, directional imbalances in the application of the weighing force upon the measurement system are avoided.
