Abstract

<P>Capteurs de pression. <P> Pressure sensors. </P><P>Le capteur est caractérisé en ce qu'il comporte des organes électroniques de détection et/ou de mesure, renfermés dans un boîtier et comprenant un transducteur pression/signal électrique et un capteur électronique relié électriquement audit transducteur pour délivrer des signaux électriques correspondant aux pressions appliquées au transducteur. </ P> <P> The sensor is characterized in that it comprises electronic organs of detection and / or measurement, enclosed in a housing and comprising a pressure transducer / electrical signal and electrically connected to said electronic sensor transducer to deliver electrical signals corresponding to the pressures applied to the transducer. Le boîtier présente une lumière d'admission de fluide destinée à être reliée à une conduite d'amenée de fluide. The housing has a fluid inlet port for connection to a fluid supply line. Le capteur comprend en outre un organe d'arrêt du fluide disposé à l'intérieur du boîtier et destiné à rendre lesdits organes électroniques étanches vis-à-vis du fluide et à délimiter une chambre de pression pour le transducteur. The sensor further comprises a stop member of the fluid disposed within the housing and intended to make said waterproof electronic bodies vis-à-vis the fluid and to define a pressure chamber to the transducer. </P><P>Ce capteur permet de détecter et/ou de mesurer la pression d'un fluide dans une conduite quelle que soit sa température.</P> </ P> <P> This sensor can detect and / or measure the pressure of a fluid in a pipe irrespective of its temperature. </ P>
