Document Type and Number:
WIPO Patent Application WO/2023/104135
Kind Code:
A1
Abstract:
The present invention relates to a tilt compensation apparatus and a tilt compensation method for a weighing system comprising a column-type load cell. The tilt compensation method includes: S1: performing tilt angle calibration and horizontal rotation angle calibration on the weighing system; S2: aligning the column-type load cell to a specified tilt angle and a specified horizontal rotation angle, and measuring a weight, a tilt angle, and a horizontal rotation angle under load; S3: calculating a weight compensation value based on the specified tilt angle and the specified horizontal rotation angle as well as the measured weight, tilt angle, and horizontal rotation angle; and S4: calculating an actual weighing weight based on an actual measured weight of the weighing system and the weight compensation value. According to the tilt compensation apparatus and the tilt compensation method therefor proposed in the present invention, accurate tilt compensation can be provided for the weighing system having a column-type load cell.
