Abstract

A temperature sensor for measuring surface temperatures. The sensor has a metal sheath containing sheath insulation and a shroud, which has a sheath receiving end to which the sheath is welded, and a distal end at the other end of the shroud. The sheath ends at the sheath receiving end of the shroud. The shroud forms an interior cavity open on one face, with the interior cavity filled with shroud insulation. Wires extend from the sheath into the interior cavity of the shroud and terminate at a junction,. The wires are supported within the shroud by the shroud insulation. The junction is thermally insulated from the shroud and from the sheath. Preferably, the shroud insulation is ceramic cement. Preferably, the shroud has a distal end, and the junction is equidistant from the sheath receiving end and the distal end, and centered in the open face of the shroud. In one embodiment, the junction is covered by shroud insulation, for forming an ungrounded junction. In another embodiment, the shroud insulation has a boundary at the open face of the shroud, and the junction is at the boundary of the shroud insulation, for forming a grounded junction. In a further invention, the temperature sensor is clamped to the pipe.
