A bed knife that acts together with a cutting blade moved past it, particularly for granulating plastic strands, consisting of individual aligned sections of the same type that are fastened to a supporting beam and whose knife edge consists of a cutter material. Each section consists essentially of ceramic cutter material and extends over the areas of feed and delivery of the material to be cut of the cut material. The section is provided with a cutout running in the direction of the bed knife that is aligned with the cutouts of all of the sections and changes into an outer surface of the section as a throat in comparison with the corresponding dimension of the cutout, with the cutouts containing a continuous bar extending through several sections. The bar presses the section against the supporting beam by means of screws passing through the throat that penetrate into the bar, with sections being connected to one another positively by the bar.

A measured-value sensor for an inductive flowmeter comprises a fluid impermeable sintered ceramic measuring tube adapted to be positioned in a conductive-liquid flow path. Magnetic coils surround the tube and are adapted to apply a magnetic field to a conductive liquid traversing the path. A pair of diametrically opposite measuring electrodes contact the liquid traversing the path for tapping an induced voltage across the electrodes representing the flow of the liquid along the path, each of the electrodes having a metallic shaft traversing the tube substantially radially and sealingly sintered to the material of the tube. The ends of the ceramic measuring tube are provided with a flange, ground at its peripheral wall surface and fastened by shrinkage stress in a bore of a steel casing. After sintering of measuring tube, conductive paths are manufactured for the formation of grounding rings and other current-conducting components by applying a platinum paste on the ceramic measuring tube and reheating again subsequently. In the process, the paste compacts to form a thin conductor film which is firmly anchored on the surface of said measuring tube.
