Abstract
The invention relates to a device and a method for the optical recording of at least one parameter on a longitudinally moved thread-type material. To enable parameters such as the diameter of a thread-type material, the diameter of a yarn package, the hairiness of a yarn etc. to be determined more simply and more accurately, an optical sensor composed of at least two individual sensors (30), in which at least one individual sensor is so constructed and arranged that at least one measured value is recorded digitally for a parameter, is to be used to record in parallel from the material at least two signals, one at least of which is clocked.
