<p>A device and a method for measuring low-amplitude signals on a moving strip material. The strip material runs over a rotatable roller (10) which is provided with at least one measuring element (12) for picking up the low-amplitude signals which, before being sent to an auxiliary device, are amplified and/or processed by an electronic circuit (16) fastened to the roller. The method and device can be used to measure electrical charges on a moving strip material.</p> |
