ABSTRACT:
The invention relates to a device for determining the operational status of an extruder that is used for the productive of a plastic profile. At least one measuring device for determining the quality of the melt is provided in an adapter part between an extrusion cylinder (3) and an extrusion nozzle (5). An especially exact determination of the extruder state is possible if the measuring device comprises a tube through which melt is continuously drawn off from the adapter part during the measurement and on which at least one pressure is disposed.
