Abstract

Dispositif de calibration (1) destiné à recevoir des capteurs de gaz (40), chaque capteur de gaz comportant une paroi d'admission (41), la paroi d'admission permettant une admission de gaz dans le capteur de gaz, le dispositif comportant : un canal d'admission (2a) de gaz et un canal d'évacuation (2b) de gaz ; des supports élémentaires (24), chaque support élémentaire étant configuré pour maintenir un capteur de gaz et pour permettre une connexion électrique du capteur de gaz ; un compartiment fluidique (10), comportant : un canal fluidique (10c), s'étendant entre le canal d'admission (2a) et le canal d'évacuation (2b) ; des ouvertures (10o), s'étendant à partir du canal fluidique (10c); une portion d'appui (14) souple, s'étendant entre chaque ouverture du compartiment fluidique (10o) ; le compartiment fluidique (10) étant mobile par rapport à chaque support élémentaire (24), de telle sorte qu'après une disposition de capteurs de gaz (40) sur chaque support élémentaire, sous l'effet d'un rapprochement du compartiment fluidique (10) par rapport aux supports élémentaires, le compartiment fluidique exerce une pression contre chaque capteur de gaz, la portion d'appui (14) entourant chaque ouverture (10o) du compartiment fluidique formant alors un joint autour de ladite ouverture.Calibration device (1) intended to receive gas sensors (40), each gas sensor comprising an intake wall (41), the intake wall allowing gas to be admitted into the gas sensor, the device comprising : a gas inlet channel (2a) and a gas outlet channel (2b); elementary supports (24), each elementary support being configured to hold a gas sensor and to allow an electrical connection of the gas sensor; a fluidic compartment (10), comprising: a fluidic channel (10c), extending between the inlet channel (2a) and the outlet channel (2b); openings (10o), extending from the fluidic channel (10c); a flexible support portion (14) extending between each opening of the fluidic compartment (10o); the fluidic compartment (10) being movable with respect to each elementary support (24), so that after an arrangement of gas sensors (40) on each elementary support, under the effect of the movement of the fluidic compartment ( 10) relative to the elementary supports, the fluidic compartment exerts a pressure against each gas sensor, the support portion (14) surrounding each opening (10o) of the fluidic compartment then forming a seal around said opening.
