Abstract

The invention relates to an electronic analytical balance with an automatic leveling function. The electronic analytical balance comprises a balance body and a leveling component. The leveling component comprises a first air spring, a second air spring, a third air spring, a fourth air spring, a first tilt angle sensor, a miniature air compression pump, a first three-way electromagnetic valve, a second three-way electromagnetic valve and a controller. The first tilt angle sensor is arranged at the bottom of the balance body, the first air spring, the second air spring, the third air spring andthe fourth air spring are respectively arranged at four corners of the bottom plate of the balance body, and the miniature air compression pump communicates with air inlets of the first three-way electromagnetic valve and the second three-way electromagnetic valve through air pipes. According to the electronic analytical balance with the automatic leveling function, automatic leveling of the balance can be achieved, manual operation is not needed, and errors caused by manual adjustment are reduced to a large extent.

Description

technical field [0001] The invention relates to the field of laboratory equipment, in particular to an electronic analytical balance with automatic leveling function. Background technique [0002] The electronic analytical balance has the advantages of simple operation, powerful functions, various precisions, and complete measuring ranges. Before using the electronic analytical balance, check whether the balance is in a horizontal state. If the level bubble of the analytical balance is not in the black circle, it needs to be leveled first. It is necessary to manually adjust the four corner columns of the electronic analytical balance to achieve a horizontal position. The steps of leveling are as follows: first observe the position of the air bubbles, and then adjust the height of the analytical balance through each leveling knob on the base of the analytical balance, so that the air bubbles reach the center of the black circle to complete the leveling. This process is cumbe...
