Patent number: 11740201Abstract: A system includes a system housing including an inlet, at least one gas sensor responsive to a first analyte gas other than oxygen within the system housing and in fluid connection with the inlet, and a sensor responsive to oxygen within the system housing and in fluid connection with the inlet. The sensor responsive to oxygen is formed to be chemically separate from the at least one gas sensor responsive to the first analyte gas other than oxygen. The sensor responsive to oxygen is responsive to a change in the concentration of oxygen arising from creation of a driving force in the vicinity of the inlet to provide an indication of a state of a transport path between the inlet of the system and the at least one gas sensor responsive to the first analyte gas other than oxygen.Type: GrantFiled: February 1, 2021Date of Patent: August 29, 2023Assignee: MSA Technology, LLCInventors: Towner Bennett Scheffler, Michael Alvin Brown, Brian Keith Davis

Patent number: 11231387Abstract: An electrochemical gas sensor includes a housing comprising a gas inlet, an electrolyte within the housing, a working electrode in ionic contact with the electrolyte, a counter electrode in ionic contact with the electrolyte and a secondary electrode in ionic contact with the electrolyte. Reaction of target gas at the secondary electrode is less than reaction of target gas at the working electrode. Electronic circuitry of the gas sensor is configured to measure an output from the working electrode and an output from the at least one secondary electrode. A correction factor is determined for correcting the output from the working electrode on the basis of the working electrode output and the secondary electrode output during an assessment in which the electrochemical sensor is exposed to the target gas for a determined period of time.Type: GrantFiled: January 24, 2018Date of Patent: January 25, 2022Assignee: MSA Europe GmbHInventors: Sebastian Ross, Kathrin Tölle, Brian Keith Davis
