Abstract
In order to create a sensor for determining the temperature averaged on the basis of the mass flow density of a medium flowing through a tube, this medium having a mass flow density gradient and a temperature gradient in the tube transverse to the direction of flow, which allows the temperature averaged on the basis of the mass flow density to be ascertained more reliably and even more exactly, it is suggested that the sensor comprise a carrier body and a resistor body held thereby, the resistor body having a measuring current flowing therethrough and a temperature-responsive variable electrical resistance which leads for its part to a correspondingly variable voltage drop, and that the resistor body be designed such that the temperature-responsive variable electrical resistance of the resistor body varies with extension of the resistor body in a transverse direction in accordance with the mass flow density.
