Abstract

A temperature transducer for the cylinder head of a liquid-cooled internal combustion engine. It comprises a housing with a lead that forwards signals from a sensor sensing the temperature of the coolant. The housing accommodates not only a coolant-temperature sensor but at least one component-temperature sensor that rests against a component in the cylinder head and has a separate lead.
