The invention relates to a device for determining the operational state of an extruder that is used for the production 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 absorber is disposed.
L'invention concerne un dispositif permettant de déterminer l'état de marche d'une extrudeuse, pour produire un profilé en matière plastique. Selon l'invention, il est prévu dans la partie adaptateur entre le cylindre d'extrusion (3) et une filière d'extrusion (5), au moins un appareil de mesure pour déterminer la qualité de la matière fondue. L'état de l'extrudeuse peut être détecté de manière particulièrement précise, du fait que l'appareil de mesure comprend un tuyau à travers lequel de la matière en fusion est extraite en continu de la partie adaptateur, pendant le processus de mesure, et sur lequel est monté au moins un capteur de pression.
