Title
(EN) SENSOR WITH ROTATABLE SENSOR ELEMENT AND PRESSURE EQUALIZATION MECHANISM
(FR) CAPTEUR AVEC ÉLÉMENT DE CAPTEUR ROTATIF ET MÉCANISME D'ÉGALISATION DE PRESSION
Abstract
(EN)
A sensor may include a sensing element (2332) retained within a storage compartment filled with a storage medium (2342), which may also be used as a calibration medium. The sensing element can include a sensing surface (2330) located away from the distal end of the sensing element, such that an inactive section of the sensing element can cooperate with a sealing member such as an O-ring to form part of the seal retaining the storage/calibration medium. The sensing element can be extended and retracted from the storage compartment to expose the sensing surface to a process medium, while preserving the storage medium within the storage compartment for post-measurement validation. The sensor further comprises a pressure equalization mechanism (2316), which is located within the sensor structure and is in fluid communication with the inline flow-cell chamber (2310).

Un capteur peut comprendre un élément de détection (2332) retenu à l'intérieur d'un compartiment de stockage rempli d'un milieu de stockage (2342) qui peut également être utilisé comme milieu d'étalonnage. L'élément de détection peut comprendre une surface de détection (2330) située à distance de l'extrémité distale de l'élément de détection de façon à ce qu'une section inactive de l'élément de détection puisse coopérer avec un élément d'étanchéité tel qu'un joint torique pour former une partie du joint conservant le milieu de stockage/étalonnage. L'élément de détection peut être rentré et sorti du compartiment de stockage afin d'exposer la surface de détection à un milieu de traitement tout en préservant le milieu de stockage dans le compartiment de stockage pour une validation post-mesure. Le capteur comprend également un mécanisme d'égalisation de pression (2316), qui est situé à l'intérieur de la structure de capteur et se trouve en communication fluidique avec la chambre de cellule à circulation en ligne (2310).
