Abstract

The invention discloses an electro-optical analytical balance with a coarse weighing device, which comprises a lifting pivot, a weighing sensor, an amplifying circuit, an analog-to-digital converter and a display, wherein the weighing sensor is arranged below an object weighing tray and is used for converting pressure into a voltage signal; the amplifying circuit is used for amplifying the voltage signal; the analog-to-digital converter is used for converting a voltage analog signal into a digital signal; the display is used for displaying the digital signal; an output end of the weighing sensor is connected with the amplifying circuit; an output end of the amplifying circuit is connected with the analog-to-digital converter; an output end of the analog-to-digital converter is connected with the display; and the weighing sensor is connected with the lifting pivot. When the electro-optical analytical balance is in use, the coarse weighing of a weighed object is completed in the analytical balance; the process of transferring the weighed object is saved; the operation is convenient; and the weighed object is prevented from being polluted to influence weighing precision.

Description

technical field [0001] The invention relates to an electro-optical analytical balance, in particular to an electro-optical analytical balance with a rough weighing device. Background technique [0002] At present, semi-mechanical and full-mechanical electro-optic analytical balances are still widely used in the field of chemical analysis, generally including balance beams, pillars, lifting lugs, fulcrum knife edges, ring codes, ring code index plates, stipples, dampers, balances Pan, pan support, pointer, projection screen, balance cover, lifting pivot, micro-adjustment lever, balance foot, balance adjustment screw, but this kind of balance is more troublesome in weighing operation, mainly because it is to prevent the object being weighed If the mass exceeds the range of the analytical balance and roughly estimates the mass of the object to be weighed, first weigh it in an ordinary balance with low precision, estimate the rough value of the object to be weighed, and then tra...
