Check system for monitoring the strain status of high pressure bottles particularly methane gas bottles for motor-vehiles

摘要

A check system for monitoring the strain status of high pressure bottles partially or entirely made of composite material, particularly methane gas bottles for motor-vehicles, comprising an optical fibre (4) wound around the bottle and including Bragg grating reflecting elements (51, 52, 53, ... 5n) to detect and turn the mechanical and thermal strain condition of the bottle (1) into electrical coded signals. <IMAGE>
