摘要：
The invention relates to a high-temperature sensor comprising contact wires in a metal tube, preferably a bent metal tube for arrangement especially inside the exhaust gas system of an internal combustion engine, and spacer bodies distributed in rows along the contact wires so as to maintain the contact wires at a predetermined distance to the inner wall of the metal tube. According to the invention, every spacer body is approximately ovoid, the diameter of the center portion of the egg being not wider than the inside width of the as yet unbent metal tube. The spacer bodies are injection-molded polymer ceramic parts molded onto the contact wires.
