Description

technical field

[0001] The invention relates to a multi-channel mixed-use weighing system and method for a multi-sensor weighing apparatus, which belongs to the field of weighing control circuit systems of a multi-sensor weighing apparatus. Background technique

[0002] With the development of the weighing instrument industry, digital multi-sensor weighing instruments have been widely used, that is, electronic multi-sensor weighing instruments use digital sensors and digital instruments. However, at present, many users still use analog multi-sensor weighing instruments in consideration of cost and use needs, but the advantages of digital multi-sensor weighing instruments in terms of high precision, good reliability, easy maintenance and strong anti-cheating capabilities are analog multi-sensor weighing instruments. incomparable.

[0003] However, no matter the multi-sensor weighing instrument with analog sensor or the multi-sensor weighing instrument with digital sensor is ...
