Abstract
An electrical resistance temperature sensor (11) contained in a stainless steel, tubular jacket (12), which has a very small diameter of approximately 1 mm, a platinum resistance coil (18) running between two joining bolts (14, 19). The resistance coil with a positive temperature characteristic of the resistance is placed in an embedding medium (17), which comprises a mixture of magnesium oxide or aluminium oxide and cerium dioxide. For use as an integrating temperature sensor for a catalytic converter, said adequately flexible temperature sensor can be wound into a roll of smooth and corrugated metal sheets and fixed by soldering in vacuo.
