  • Electrochemical gas sensor
    Patent number: 8083914
    Abstract: An electrochemical gas sensor is disclosed which comprises a gas sensing electrode and a counter electrode disposed within a housing, the housing having an aperture for gas ingress, the gas sensing electrode and counter electrode being separated by a region containing electrolyte, and means for connecting the gas sensing electrode and the counter electrode to a sensing circuit. An electrolyte-absorbing element is disposed inboard of the aperture, between the housing and the gas sensing electrode, in order to absorb electrolyte passing through the gas sensing electrode whilst maintaining a gas path through the electrolyte-absorbing element.
    Type: Grant
    Filed: January 9, 2008
    Date of Patent: December 27, 2011
    Assignee: Life Safety Distribution AG

  • Gas sensor assembly and method
    Patent number: 7282168
    Abstract: A gas sensor assembly comprises a housing (65) including a bore (61). A pin (50) extends through the bore (61) and an O-ring (100) is located in the bore. The O-ring (100) contacts the pin (50) and parts of the bore (61) so as to be restrained against movement in both lateral and axial directions. Two- and three-shot molding processes are described for fabricating the assembly.
