Measuring arrangement for use with sensor element for determining concentration of particles in gas mixtures, particularly soot, comprises temperature measuring element that is integrated in sensor element with control unit

摘要

The measuring arrangement (10) comprises a sensor element (12) with a measuring element. The measuring element is exposed to a gas to be identified. A temperature measuring element is integrated in the sensor element with a control unit (18). A modified electrical power is applied in phases to the temperature measuring element upon a signal of the control unit. Two measuring electrodes are arranged on an electrically isolating substrate that contains alumina or alkaline-earth oxide. An independent claim is also included for a method for determining a concentration of particles in gas mixtures, particularly soot.
