A measuring arrangement is provided with a soot filter for use in flowing, soot particle-bearing gases, as well as a method for monitoring the operability of a soot filter arranged in an exhaust gas conduit, wherein at least one component stream of an exhaust gas stream flows through at least one molded element which is open-pored at least in the flow direction, and wherein the temperature of the molded element is measured with at least one temperature probe. In the measuring arrangement the soot filter is allocated at least one soot sensor, which has at least one molded element which is openpored at least in the flow direction, at least one electric heating element, and at least one temperature probe. The measuring arrangement and method make possible a monitoring of the operability of a soot filter in a reliable and direct manner.
