Abstract

Afin de mesurer la pression d'un fluide dans un tuyau flexible (20), on compresse le tuyau entre deux mâchoires (12, 14) jointes par un pont (16). La compression du tuyau entre les mâchoires permet la constitution d'une contrainte dans le pont, ladite contrainte pouvant être mesurée par une jauge de contrainte (28, 30) reliée au pont. Au fur et à mesure que la pression interne dans le tuyau se modifie, la contrainte détectée par la jauge de contrainte se modifie également et produit ainsi un résultat de sortie représentatif des variations de pression dans le tuyau. La température du contenu du tuyau peut également être contrôlée par des opérations de lecture de la température effectuées depuis l'extérieur du tuyau.
