Title (EN) FLUID PRESSURE MEASUREMENT DEVICES OF AN INJECTION SYSTEM
(FR) DISPOSITIFS SERVANT A MESURER LA PRESSION D'UN FLUIDE DANS UN SYSTEME D'INJECTION
Abstract:
(EN) The present invention provides pressure measuring devices having a sensor to detect the force upon at least a portion of a contact surface of a syringe plunger during pressurization of a fluid medium within the syringe. A determination of the pressure of the fluid medium within the syringe is thereby enabled.
(FR) L'invention concerne des dispositifs servant à mesurer une pression et comportant un détecteur servant à détecter la force exercée sur au moins une partie d'une surface de contact d'un plongeur de seringue pendant la mise sous pression d'un milieu liquide à l'intérieur de la seringue. Ceci permet de déterminer la pression de ce milieu liquide à l'intérieur de la seringue.
