Abstract
A balance (1) with a weighing pan (3) inside a weighing compartment (2) enclosed by a draft shield (4) has at least one thermoelectric module (16) that is arranged outside of the weighing compartment (2) and thermally connected to a stationary part of the balance (1). At least one vertical wall (8) of the draft shield (4) has a lower end portion in thermal connection with the thermoelectric module (16). The vertical wall (8) is configured in such a way that a temperature gradient develops in the vertical wall (8), wherein the temperature increases from the bottom to the top of the wall (8).
Claims19
A balance (1), comprising a weighing pan (3), a weighing compartment (2) surrounding the weighing pan on all sides, a draft shield (4) enclosing the weighing compartment, and a stationary part, wherein the draft shield has at least one vertical wall (8) formed as a component of the stationary part, wherein at least one thermoelectric module (16) is arranged outside of the weighing compartment (2) near the stationary part in a lower portion of the balance and thermally connected to the stationary part, wherein the at least one vertical wall (8) has a lower end portion in thermal connection with the thermoelectric module (16), and wherein the at least one vertical wall (8) is configured in such a way that a temperature gradient with a bottom-to-top temperature increase develops in said at least one vertical wall (8).
