ABSTRACT:
A shielded thermocouple assembly includes a mounting pipe having a flange a first end thereof and extending outwardly therefrom, and a mounting plug having a first end connected to a second end of the mounting pipe, the mounting plug having a recess in a second end thereof defined in part by a circular side wall having at least one opening therein. A fine-wire thermocouple is fixed in the mounting plug and extends into the recess. A rigid shield pipe is disposed concentrically around and spaced from the mounting pipe, the shield pipe being closed by a shield plate proximate the mounting plug second end. An inlet extends through a side wall of the shield pipe in alignment with a side wall of the mounting plug recess, and an outlet extends through the side wall of the shield pipe and is in axial alignment with the inlet. The inlet directs incoming air against a curved portion of the mounting plug which directs the incoming air around the mounting plug past the opening, from whence the air flows to the outlet and out of the assembly. Thus, the incoming air flows past the thermocouple to permit the thermocouple to sense a temperature of the incoming air, but fragments and particles carried by the incoming air are substantially routed away from contact with the thermocouple.
