摘要： 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.

摘要： A sensor for magnetic-inductive flowmeters in defined by a sensing tube (3) disposed in a steel housing (1) and fitted with sensing electrodes (5). Two opposing magnetic coils (6) are mounted to the exterior of the tube. The coils (6) have a bolt-shaped core (7) which have saddle-shaped bases that engage the outer wall of sensing tube (3). A simplified mounting of magnetic coils (6) in steel housing (1) is achieved with flange-like webs (12) mounted adjacent an upper end (11) of coil core (7). The webs are positioned within steel housing (1) by support surfaces (29). A winding bobbin (14) is constructed of two semi-cylindrical halves (15,16) which are disposed about coil core (7) and are locked to each other with a spring catch (22). The coil wire (17) is wound about the bobbin (14) secured to core (7).

摘要： A magnetoinductive flowmeter encompasses a ceramic measuring tube as a conduit for a medium whose flow rate is to be measured, and a measuring electrode featuring a cermet body. The measuring tube is mounted in the wall of the measuring tube with its side that faces the medium conductively or capacitively connecting to the medium while its side facing away from the medium connects to a measuring line. The cross-sectional surface area of the cermet body is larger at its end facing the medium than at its other end facing away from the medium. The result is a measuring electrode that fully meets the respective requirements at either end notwithstanding minimized material consumption in making the electrode. A method for producing a measuring tube for the flowmeter is also disclosed.
