| 摘要 |
A device for detecting excess thickness of material beyond a fixed limit, characterized in that it has a yielding limiter (3) placed above a hole (2) in a guide (1), while a sensor (4), preferably an inductive proximity sensor, is situated under the hole (2) in the guide (1), and the base for measurement is determined by the distance of the yielding limiter (3) from the guide (1) with hole (2).<IMAGE>
