Abstract

See full text

A weighing device is provided that suppresses air convection currents generated in a weighing chamber in the opening/closing of a door of the chamber with a relatively simple configuration. A weighing space is partitioned into two spaces with a partition plate to form a lower small-capacity weighing chamber, which enables to settle down the convection in a short time if convection is generated in the chamber. Suspended walls adjacent to the doors are attached to the partition plate edge sides along the door opening/closing directions. Even when a door is opened, warm air stagnant in the upper space in the chamber is restricted or blocked to flow out to the outside by the suspended walls, which generates no convection or slight convection, which settles down in a short time, without adverse effect on a weighing operation. The upper space may be utilized for another purpose such as a neutralization chamber.
