(FR) DISPOSITIF POUR DES MESURES DE CONCENTRATION ET CHAMBRE DE STÉRILISATION ET MACHINE DE REMPLISSAGE COMPRENANT LEDIT DISPOSITIF
Abstract
(EN)
A device (36, 100, 200) for measurement of concentration of an oxidizable gas is disclosed, which comprises a catalyst (102) inside a housing (101, 201). The catalyst is surrounded by insulation (105) inside the housing. The device (100, 200) further comprises at least two thermometers, one of which is located at the inlet of the device, and one being located inside the catalyst (102). The device also has means for calculating a concentration based on the temperature measurements. A sterilization chamber and a filling machine having a device according to the main claim are also disclosed.
(FR)
L'invention porte sur un dispositif (36, 100, 200) pour la mesure d'une concentration d'un gaz oxydable, qui comprend un catalyseur (102) à l'intérieur d'un boîtier (101, 201). Le catalyseur est entouré par une isolation (105) à l'intérieur du boîtier. Le dispositif (100, 200) comprend en outre au moins deux thermomètres, dont l'un est situé à l'entrée du dispositif, et l'autre est situé à l'intérieur du catalyseur (102). Le dispositif a également des moyens pour calculer une concentration sur la base des mesures de température. L'invention porte également sur une chambre de stérilisation et sur une machine de remplissage ayant un dispositif selon la revendication principale.
