  • Flue gas sensor with water barrier member
    Patent number: 8707759
    Abstract: A flue gas sensor of a combustion device is disclosed. The flue gas sensor may include a housing and a gas detector disposed within the housing, wherein the gas detector detects or measures at least one gas in a flue gas stream of the combustion device. The housing may also include a water barrier member through which the at least one gas comes into contact with the gas detector.
    Type: Grant
    Filed: March 4, 2011

    Assignee: Carrier Corporation
    Inventors: Marc W. Roland, Daniel J. Dempsey
  • Method and apparatus for emissions detection in a combustion appliance
    Patent number: 8662885
    Abstract: A furnace system that generates heat by combustion is provided. The furnace system includes a sensor (100) that detects a gas concentration. The sensor is in communication with the flue gas (15). A controller is in communication with the sensor. The controller monitors the gas concentration and acts to control or deactivate the furnace.

  • Flue Gas Sensor With Water Barrier Member
    Publication number: 20110226039
    Abstract: An improved flue gas sensor of a combustion device is disclosed. The flue gas sensor may include a housing and a gas detector disposed within the housing, wherein the gas detector detects or measures at least one gas in a flue gas stream of the combustion device. The housing may also include a water barrier member through which the at least one gas comes into contact with the gas detector. By keeping water and water vapor away from the gas detector, premature failure of the flue gas sensor caused by corrosion may be prevented.
