The invention relates to a method for the voltage-controlled performance regulation of the heating of an exhaust-gas probe in the exhaust system of an internal combustion engine. The aim of the invention is to provide a method in which the operating temperature of the probe is achieved in the shortest possible time without damage to the probe. To achieve this, the heating voltage during the heating phase of the probe is rapidly brought up to a high temperature in a start phase in relation to a subsequent phase, or a dramatic leap in temperature is achieved, preferably up to the full operating voltage and the heating voltage is then continuously or quasi-continuously reduced.

Method for the voltage-controlled performance regulation of the heating of an exhaust-gas probe

A sensor element is provided for gas sensors, in particular to determine particles in gas mixtures, the sensor element including at least one electrochemical measuring element exposed to the gas mixture to be determined, and at least one temperature-measuring element integrated into the sensor element. The temperature-measuring element includes a resistor track, which has an electric resistance of less than 180 Ohm at 0&#xb0; C. The resistor track may thus be produced by thin-foil technology, such as screen printing, for example.

Sensor element for gas sensors and method for operating same

A sensor for determining the concentration of particulates in gas mixtures is described, a soot sensor in particular, having a ceramic sensor body surrounded by a metallic housing and having a first and a second measuring electrode. In this instance, the first measuring electrode is connected to the metallic housing of the sensor or the metallic housing of the sensor is designed as the first measuring electrode. By additional electrodes on the ceramic body, the sensor is operable also as a lambda sensor.
