Title
(EN) INJECTOR PRESSURE CALIBRATION SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ D'ÉTALONNAGE DE PRESSION D'INJECTEUR
Abstract
(EN)
A calibration system for calibrating a pressure output of a fluid injector having a housing configured for connecting to the fluid injector; a drive member engagement portion configured for contacting a drive member of the fluid injector; a compressible member, which may have a known modulus of compression, connected at its proximal end to the drive member engagement portion, wherein the compressible member is compressed with movement of the drive member of the fluid injector between a first, uncompressed position and a second, at least partially compressed position of the fluid injector in a distal direction; and a sensor connected to the compressible member is described. The sensor is configured for measuring at least one of a force imparted by the drive member and a displacement of the drive member when the compressible member is in the second, at least partially compressed position. The system may generate a calibration curve for the drive member of the fluid injector and allow the generation of a fault condition. Methods for calibrating a fluid injector are also described.

L'invention concerne un système d'étalonnage pour étalonner une sortie de pression d'un injecteur de fluide, comprenant un boîtier conçu pour être relié à l'injecteur de fluide ; une partie de mise en prise d'élément d'entraînement conçue pour venir en contact avec un élément d'entraînement de l'injecteur de fluide ; un élément compressible, qui peut comprendre un module de compression connu, relié, au niveau de son extrémité proximale, à la partie de mise en prise d'élément d'entraînement, l'élément compressible étant comprimé avec un mouvement de l'élément d'entraînement de l'injecteur de fluide entre une première position non comprimée et une seconde position au moins partiellement comprimée de l'injecteur de fluide dans une direction distale ; et un capteur relié à l'élément compressible. Le capteur est conçu pour mesurer une force exercée par l'élément d'entraînement et/ou un déplacement de l'élément d'entraînement, lorsque l'élément compressible est dans la seconde position au moins partiellement comprimée. Le système peut générer une courbe d'étalonnage pour l'élément d'entraînement de l'injecteur de fluide et permettre la génération d'un état de défaut. L'invention concerne également des procédés pour étalonner un injecteur de fluide.
