A sensor assembly for use within a flow conduit includes a sensor shield port extending between inner and outer ends of the sensor shield port through a wall of the flow conduit. The sensor shield port includes a port body defining a bore and extending between inner and outer surfaces of the port body. The sensor shield port further includes an outer port wall extending from the outer surface of the port body towards the outer end of the sensor shield port and an inner port wall extending from the inner surface of the port body. The sensor shield port includes one or more tabs extending from the inner port wall towards the inner end of the sensor shield port. The sensor assembly further includes an exhaust sensor inserted and removably coupled within the bore of the sensor shield port.
