ABSTRACT:
A temperature sensor is proposed which is intended in particular for measuring the temperature of the air aspirated by an internal combustion engine which operates by electronic fuel injection. The temperature sensor includes a carrier body receiving electrical connections and a temperature-dependent electrical resistor element which is surrounded by a protective sheath. The protective sheath has apertures which permit free access to the temperature-dependent electrical resistor element by the medium to be measured. The protective sheath is advantageously capable of being connected in a positively-engaged manner with a protruding catch of the carrier body. As a consequence of the free access of the medium to be measured to the temperature-dependent electrical resistor element, a very short response time on the part of the temperature sensor to changes in temperature is assured.
