A device for contactless measurement of the diameter of a moving yarn or a yarn-like textile formation

摘要

The device for contactless measurement of at least one property of a moving yarn or of a yarn-like textile formation comprises an optical line sensor with a plurality of pixels arranged next to each other in at least one row. The optical line sensor (1) is integrated into one semiconductor integrated custom ASIC circuit (4) jointly with at least a part of the electronic circuits (3) for processing and/or for evaluating the signal of the optical line sensor (1), and the electronic circuits (3) for processing and/or evaluating the signal of the optical line sensor are integrated with the optical line sensor (1) on a common semiconductor die (2) and/or seated in a common case (5).
