Abstract

Capteur de pression à reseau de Bragg. Ce capteur, qui s'applique notamment à l'industrie chimique, comprend par exemple une fibre optique (10) et un réseau de Bragg (14) formé dans une portion (14) de la fibre, qui est soumise à la pression (P), et des moyens (20) de maintien latéral de cette portion. Cette portion et soumise à une précontrainte en compression dont, la valeur est faible devant l'étendue de mesure du capteur.
