Gas Sensor Assembly with Interior Heat Dissipation, Sealing, and Support Plug

A gas sensor assembly comprising:

• a substrate including a base having electronics mounted thereon and a beam having at least a sensor mounted thereon;
• a plug located on the beam of the substrate between the electronics and the sensor;
• a collar surrounding the beam of the substrate and including one end coupled to the plug;
• a jacket surrounding the base of the substrate and including a neck at one end coupled to the plug and an opposed open end;
• and
• a connector including a base extending into and coupled to the open end of the jacket.

A gas sensor assembly comprising:

• a housing;
• a substrate located in the housing, the substrate including a high temperature gas sensor end and a lower temperature electronics end;
• and
• a thermally conductive plug mounted in the housing to the substrate, the plug sealing the sensor end of the substrate from the electronics end of the substrate and transferring the heat generated at the high temperature sensor end of the substrate through the substrate, the thermally conductive plug, and the housing.
