Title (EN) FLUID PRESSURE DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION DE PRESSION DE FLUIDE
(JA) 流体圧力検出装置
Abstract:
(EN) Provided is a fluid pressure detection device whereby a change in pressure of a fluid passing through the inside of a pipe can be accurately detected from outside the pipe. A device for detecting the pressure of a fluid passing through the inside of a pipe, the device being provided with: a substrate 10; a piezoelectric element 20 provided on a top surface of the substrate 10; a support body 30 for supporting the top surface of the substrate 10, the support body 30 being annular so as to surround the piezoelectric element 20; and a lid body 40 provided so as to close a top opening of the support body 30; the substrate 10 being pressed via the support body 30 and a pipe being deformed by a bottom surface of the substrate 10.
(FR) L'invention concerne un dispositif de détection de pression de fluide grâce auquel un changement de pression d'un fluide traversant l'intérieur d'un tuyau peut être détecté avec précision depuis l'extérieur du tuyau. L'invention concerne plus précisément un dispositif de détection de la pression d'un fluide traversant l'intérieur d'un tuyau, le dispositif comportant : un substrat (10) ; un élément piézoélectrique (20) disposé sur une surface supérieure du substrat (10) ; un corps de support (30) pour supporter la surface supérieure du substrat (10), le corps de support (30) étant annulaire de façon à entourer l'élément piézoélectrique (20) ; et un corps de couvercle (40) disposé de façon à fermer une ouverture supérieure du corps de support (30) ; le substrat (10) étant pressé par l'intermédiaire du corps de support (30) et un tuyau étant déformé par une surface inférieure du substrat (10).
(JA) 管内を通過する流体の圧力変化を管外から正確に検出することの可能な流体圧力検出装置を提供する。 管内を通過する流体の圧力を検出する装置であって、基材10と、基材10の上面に設けられた圧電素子20と、圧電素子20を囲むように環状であって基材10の上面を支持する支持体30と、支持体30の上部開口を閉じるように設けられた蓋体40と、を備え、支持体30を介して基材10を押圧し、基材10の下面で管を変形させる。
