Abstract: A temperature-dependent measuring resistor is connected to a reference resistor in series, wherein this series connection is flowed through by a constant impressed current. A connection point located between the two resistors is connected to the N-input of a first feedback differential amplifier, whose P-input is supplied with direct current voltage tapped from a voltage divider. During a temperature increase in the area of the measuring resistor, the potential increases at the output of the first differential amplifier, which delivers the constant impressed current and is connected to the measuring resistor, while the potential at the output of the differential amplifier falls when the temperature falls. The temperature-dependent voltage signal that is output at the differential amplifier is supplied in subtracting connection to the P-input of an after-connected second differential amplifier, whose output is connected to a measurement unit for measuring the voltage characteristic of the temperature. In a preferred embodiment, the measuring resistor made of platinum or of a platinum-based alloy is directly mounted on a substrate made of ceramic (Al2O3), which forms a thin-layer component. On the surface of the thin-layer component the reference resistor and the micro-module are mounted in addition. The temperature sensor has, because of an evaluation circuit constructed as a micro-module, a compact structural form and can be used up to a temperature of approx. 300° C.
