Abstract

A measurement arrangement includes four electrically heated resistors which are arranged in gas paths and are connected to form a Wheatstone bridge, where each of two resistors which are diagonally opposite each other in the Wheatstone bridge are contained in a respective component arranged on a common heated carrier, each respective component is assigned to one heating resistor arranged near the component on the carrier, and where an unbalanced state of the Wheatstone bridge is compensated for by variably energizing the heating resistors.
