Patent number: 11067551Abstract: The present disclosure relates to a device for measuring the amount of oxygen present in a gas to be analyze. The device includes at least one member for measuring the amount of oxygen, a first inlet in communication with the measuring member for the supply of gas to be analyzed, and an outlet for the discharge of said analyzed gas. The device also includes a second inlet intended to communicate with the measuring member, allowing said device to be supplied selectively with a calibration gas having a known amount of oxygen, such that the measurement of the amount of oxygen present in the calibration gas makes it possible to determine a potential drift of the measurement of said measuring member relative to the actual known amount of oxygen present in the calibration gas.Type: GrantFiled: January 5, 2018Date of Patent: July 20, 2021Assignees: ZODIAC AEROTECHNICS, L'Air Liquide Societe Anonyme Pour L'Etude et L'Exploitation Des Procedes Georges ClaudeInventors: Olivier Vandroux, Nelly Giroud, Norbert Ponsinet, Jorge Gaspar, Gilles Delaitre, Jean-Michel Cazenave, Philippe Boggetto
