Abstract

Ein elektronisches Sicherheitssystem zur Detektion eines Wellenbruchs und zur Unterbrechung der Antriebsenergiezufuhr umfasst mindestens einen in Wellenlängsrichtung fest verlegten, mit der Welle (1) rotierenden und an der Eintrittsseite (14) mit einem mit der Lichtquelle (18) verbundenen Mess-Lichtleiter (13). Bei einem Wellenbruch wird der Mess-Lichtleiter durchtrennt, wobei das Ausbleiben des Lichts an der Austrittsseite (15) von einem optischen Sensor (19) registriert und über eine Auswerte- und Steuerelektronik (20, 21) als Signal zur Abschaltung der weiteren Energiezufuhr an einem Kraftstoff-Absperrventil (22) dient. Der Mess-Lichtleiter ist an einer an beiden Enden mit der Welle verbundenen Messhülse (4) fixiert.
