Abstract (en)
The eccentric screw pump (1) has a rotationally driven rotor (3) mounted in a stator (2), whereby the stator consists at least in areas of an elastic material. At least one sensor (8) is provided for the stator by which compressions and/or movements of the stator or elastic material are measured in the course of the rotation of the rotor. The sensor may be a pressure transducer, force transducer and/or displacement transducer. The measurement sensor may be integrated at least in part in the elastic material of the stator.
