Abstract

Sensor for protecting optical guides against breakages by twisting, which consists of two independent moving parts, conductors of electricity, which are attached to an optical guide g situated along its axis of symmetry, by means of a clamp on which some screws t exert pressure, and which through twisting the optical guide 9 beyond a limit angle [alpha] enter into contact and close an electrical circuit, thus supplying a signal that can activate an alarm or the safety device of a machine for protecting the guide from undesired twisting. The twisting limit angle [alpha] and therefore the sensitivity can be preset by the separation s between the parts, the diameter [phi] and the angle [beta]. In addition to the problem of the operatives' safety in those industrial applications in which optical guides are used for conducting laser radiation, the economic problem is solved, preventing breakage before this occurs.
