An inductive flowmeter with a permanent magnet is disclosed for electrically conductive liquids such as, for instance, sodium, comprising a pair of magnet poles which are disposed diametrically outside a pipe carrying the liquid, and electrodes which are conductively connected to the liquid. Through a new arrangement of the electrodes, not only the measured signal is increased but the dependence of the measured signal on the electric conductivity and the temperature of the liquid, is compensated...

The primary and secondary core sections of a split core transformer forming an inductive coupler are secured within separate sealed containments in intimate contact with a thin non-magnetic portion of the respective containments which permits inductive coupling and decoupling of the primary and secondary core sections in corrosive fluid environments such as water. The sealed containments isolate the core sections from contact with the corrosive environment thus permitting the use of efficient la...

An improved inductive device has a U-shaped ferrite magnetic core with a base and a pair of parallel legs integrally extending from the opposite ends of the base. A straight ferrite magnetic core is disposed between the opposed core legs to define airgaps respectively between the ends of said straight core and the legs. A winding is disposed to surround the straight core. Each of the core legs is formed to have a generally flush surface over substantially the entire length thereof such that the ...

A make and break inductive connector for transferring electrical energy, e.g. under water, by transformer action comprising two separable body parts (11) having mateable end faces (13). Each part has a cavity (15) extending into it from its end face and a magnetic pot core half (17) housed in the cavity so that the end of the pot core half is flush with the body part end face. Within an annular cavity (23) of each core half there is housed a toroidal electrical winding (25) and potting compound ...

A sheet winding (7) in a transformer is made with double-curved conductor sheets. Some of the winding turns are mutually different as regards the curvature visible in an axial section. This has been achieved by arranging a number of filling members at each one of the end surfaces of the winding. Each filling member contains several turns of a filling tape (14), which are evenly distributed in a group of mutually adjacently positioned winding turns wound from a conductor sheet (9). Because the fi...

An induction device comprises a winding support with a base having connection points. The upper side of the base carries a centering member having an exterior surface that defines either a cylindrical or conical surface co-axial with the cylindrical central portion of a core. A winding is provided about the central portion of the core. The core has a non-circumferentially or rotationally symmetrical upper flange. A ferromagnetic adjusting core in a form of a cap is arranged over the core that ca...

A method of manufacturing an inductive element for SMD applications comprises the following steps: a) providing a number of predominantly parallel electroconductive wires in the mould of an injection-moulding device, b) circumferentially providing a part of the wires with a synthetic resin by injection moulding, in such a manner that the ends of the wires remain free, c) providing an envelope of a soft-magnetic material around the circumferentially injection moulded part of the wires, and d) res...

The invention relates to an inductive transmitter for transmitting measurement data and electrical energy between two components (1, 2) that move in relation to each other, having at least one primary (3, 5) and at least one secondary transmitter component (4, 6). There is one transmitter (3, 4) for transmitting measurement data and one transmitter (5, 6) for transmitting electrical energy, with the primary (3, 5) and secondary (4, 6) transmitter components being disposed in separate chambers (7...

An inductive device composed of a bead (10) of magnetic material, such as ferrite, has an aperture through which an electrical conductor (13) is adapted to pass and a reset winding (14) wound thereon and connected to a source of constant current. The constant reset current resets the bead of magnetic material so that the maximum volt-second absorbtion capability of the bead is available for preventing destructively high current spikes from flowing through the electrical conductor. The inductive ...

In an inductive sensor a ferrous core is provided and has generally opposed first and second ends. A winding assembly surrounds the core. First and second magnets are coupled to the first and second ends of the core and are oriented relative to one another so that like magnetic poles are opposing one another along a length defined by the core.
