Abstract

A light wave conductor-sensor for tension, comprises a primary coated light wave conducting element, at least one coil wound on the primary light wave conducting element and forming together with the latter a sensor core, and a compound including longitudinally extending tension-proof fibers embedded in a synthetic plastic matrix, the compound forming a casing for the sensor core.
