Title (EN) METHOD FOR DECREASING BASELINE UNDER HIGH TEMPERATURE OF GAS SENSOR
(FR) PROCÉDÉ DE RÉDUCTION DE LIGNE DE BASE À HAUTE TEMPÉRATURE DE CAPTEUR DE GAZ
Abstract:
(EN) Systems and methods for preventing reaction between a sealing material (109) such as epoxy and an electrolyte material within a carbon monoxide or other gas electrochemical sensor (100) are provided. In general, the electrochemical sensor (100) comprises a gas diffusion working electrode (110), a counter electrode (116), and optionally, a reference electrode (114). Each electrode (110, 116, 114) is in contact with an aqueous electrolyte. The gas sensor (100) may comprise a tab (117) located proximate to gaps (108) in the housing (102) of the sensor (100), wherein the tab (117) prevents any sealing material (109) that fills the gaps (108) from entering the interior of the housing (102). In some embodiments, the tab (117) may be attached to a counter electrode (116). In some embodiments, the housing (102) may comprise a slot (132) located about the gaps (108), wherein the tab (117) fits into the slot (132) of the housing (102).
(FR) L'invention concerne des systèmes et des procédés servant à prévenir une réaction entre un matériau d'étanchéité (109) tel que de l'époxy et un matériau électrolytique dans un capteur électrochimique de monoxyde de carbone ou d'autres gaz (100). En général, le capteur électrochimique (100) comprend une électrode de travail à diffusion de gaz (110), une contre-électrode (116), et éventuellement, une électrode de référence (114). Chaque électrode (110, 116, 114) est en contact avec un électrolyte aqueux. Le capteur de gaz (100) peut comprendre une languette (117) située à proximité d'espaces (108) dans le boîtier (102) du capteur (100), la languette (117) empêchant tout matériau d'étanchéité (109) qui remplit les espaces (108) de pénétrer à l'intérieur du boîtier (102). Dans certains modes de réalisation, la languette (117) peut être fixée à une contre-électrode (116). Dans certains modes de réalisation, le boîtier (102) peut comprendre une fente (132) située autour des espaces (108), la languette (117) s'ajustant dans la fente (132) du boîtier (102).
