OPTICAL FIBER TRANSDUCER

摘要

A measurand is detected by a sensor element (17) forming part of a transducer unit (10) which is filled to an optical fibre or fibre capable (11) such that the fibre (11) is bent or curved to an abnormal level which introduces a measurable loss in the transmission characteristics of the fibre (11). The transducer unit (10) has three spaced clamp members (12, 13, 14) arranged to be clamped along the length of the fibre (11). The sensor element (17) is fitted between clamp members (12, 13) and the fibre (11) is guided over a bar (15) located between clamp members (13, 14).
