Abstract

The invention relates to a weighing device. The device comprises a weighing box, a weighing element, a bearing piece, a lifting assembly and an air supply assembly, wherein the weighing box is provided with an accommodating cavity and a first through hole communicated with the accommodating cavity; the weighing element is provided with a weighing body corresponding to the first through hole; the bearing piece is provided with a weighing end and a bearing end, the bearing piece can reciprocate in the axial direction of the first through hole, and an outer wall of the bearing piece and the inner wall of the first through hole are arranged at an interval; the lifting assembly is used for driving the bearing piece to reciprocate in the axial direction of the first through hole so that the weighing end is matched with or separated from the weighing body in a bearing mode; an air supply outlet of the air supply assembly communicates with the containing cavity. According to the weighing device, dry shielding gas is introduced into the containing cavity through the gas supply assembly, and the shielding gas introduced into the containing cavity can be discharged through the gap between the outer wall of the bearing piece and the inner wall of the first through hole, so the gas in the containing cavity can be replaced, the weighing element is enabled to work in a proper environment all the time, and weighing precision is ensured.

Description

technical field [0001] The invention relates to the technical field of sample weighing, in particular to a weighing system and a weighing device. Background technique [0002] After the sample is processed or tested in a specific test environment, it is often necessary to use a weighing device to weigh the sample. For example, the sample to be weighed needs to be subjected to high temperature (the test temperature of individual samples needs to be above 600°C), high humidity (the test humidity of individual samples needs to be above 90% RH) or corrosive (acetic acid, n-hexane, ethyl acetate, etc.) or alcohols and other atmospheres) and other test environments for processing or testing before weighing. In the process of weighing samples by traditional weighing devices, it is easily affected by the test environment, which affects the measurement accuracy. Contents of the invention [0003] Based on this, it is necessary to provide a weighing system and a weighing device fo...
