Operating principle

The sensor measures the shadow cast by the yarn on the
photoreceiver.  State of the art opto-electronics ensure a
supreme stability in even the most adverse environments.
This allows an absolute measurement and leads to a detector
capability of even the faintest gradual diameter changes.
From the rapid succession of measured diameter the yarn
profile is reconstructed and digitally analyzed using
sophisticated software algorithms.
