Embodiment Construction

[0041] exist figure 1 A precision weighing device 10 with a weighing device 14 and a windshield 12 is shown in . The wind shield 12 serves to surround the weighing chamber above the weighing device 14 and thus protects the weighing pan of the weighing device 14 from external influences, such as air movement, electrostatic attraction or thermal radiation, and thus ensures precise Measurement.

[0042] The windbreak 12 has a front panel 18 , a rear wall 20 and two opposite side walls 22 . Furthermore, a cover 24 is provided which closes the windshield 12 from above. The rear wall 20 is fixedly connected to the weighing device 14 and forms a support for a cover 24 . The side walls 22 respectively have side panels 26 which can be positioned in a closed position and an open position ( figure 2 ) to move between. Side panels 26 as well as front panel 18 extend from cover 24 to weighing device 14 .

Abstract

A weighing-chamber base (34) for a precision balance (10) has a weighing-base portion (98) and two side pieces (100) which are arranged vertically on the weighing-base portion (98), on opposite peripheries (102) of the weighing-base portion (98), and are located outside the draught shield. A draught shield (12) is provided for a precision balance (10), having a weighing-chamber base (34) according to the invention and having at least one side panel (26), which can be displaced between an open position and a closed position, wherein the side pieces (100) of the weighing-chamber base (34) form part of the side walls (22) of the draught shield (12). Also provided is a precision balance (10) having a housing and a weighing-chamber base (34) according to the invention or a draught shield (12) according to the invention, wherein the side pieces (100) of the weighing-chamber base (34) form part of the side walls of the housing.

Description

technical field [0001] The invention relates to a weighing chamber bottom for a precision weighing device and a draft protection for a precision weighing device with such a weighing chamber bottom. Background technique [0002] It is generally known to mount a draft shield on a precision weighing device, which surrounds the chamber above the weighing pan of the precision weighing device. The wind protection has the task of preventing the weighing process from being disturbed by external influences such as air movement, electrostatic attraction or thermal radiation. In order to be able to place the item to be weighed on the weighing pan, such a draft shield has side panels which can be moved between a closed and an open position. In order to clean the draft shield or to maintain unhindered access to the weighing pan, it is known from the prior art that the side and front panels and the cover of the draft shield can be completely removed. However, in order to be able to clea...
