Abstract

Temperature sensor (10), with a temperature/resistance characteristic having a plateau, in the form of a series circuit of an NTC thermistor (11) and a PTC thermistor (12). The PTC thermistor (12) has a Curie temperature such that it operates in the operating temperature range in its characteristic region beyond its resistance maximum. <IMAGE>
