A sensor assembly for monitoring process parameters in an adverse environment is disclosed. The sensor is mounted on an exterior side of a chamber for curing polymeric materials using radiation. A shutter on the sensor assembly separates a passageway in which a sensor element is disposed from the adverse environment. A gas source pressurizes the passageway so that the passageway has a positive pressure when the shutter is in an open position as well as a closed position. A mounting device mounts the sensor assembly to an inerting tube of the curing chamber so that the sensor element will sense radiation inside the chamber when the sensor assembly is mounted outside the chamber. |
