Abstract
A temperature sensor includes a substrate, a platinum resistor arranged on at least one surface of the substrate, a protective layer covering at least a portion of the platinum resistor and a cover layer covering at least a portion of the protective layer, the cover layer including Al2O3, SiO2 and Y2O3. The cover layer may also include B2O3. A conductive wire may be electrically connected to the platinum resistor. A glass ceramic may be covering at least a portion of the conductive wire, platinum resistor, protective layer and cover layer.
