摘要： A measuring device for contact-free measuring of a rotation angle and/or torque of shaft comprises two coaxial bodies fastened on shaft stubs and rotatable relative to one another. The bodies have on their adjacent outer surfaces an equal number of areas having high and low electrical conductivity alternating in the circumferential direction. The bodies are enclosed by coils connected in a Wheatstone bridge circuit. A high-frequency alternating current flows through the coils and produces a magnetic alternating field which generates eddy currents in the outer surface areas of the two bodies in proportion to the magnitude of the surfaces of the two bodies penetrated by the magnetic alternating field.

摘要： To provide an unyielding support surface for a film-type, typically thick-film resistor (10) made of pressure-responsive resistance material, an unyielding pressure-tight mass of insulating material, for example a melt of glass, ceramic, or suitable plastic, is introduced into a wall portion of a wall element (11) in which a fluid pressure medium, such as high-pressure fluid for injection to a Diesel engine, is retained. The insulating mass is, preferably, formed as a plug element, for example retained within a metal screw which, simultaneously, can form a venting screw for the fuel injection system. One or two electrical conductors (12, 13) pass through the plug element, which if a metal screw, surrounds the insulating mass, the resistance element can extend over the edge of the metal which, then, can form a ground or return connection. The surface of the plug element is either flush with the surface of the wall or, for example, forms a laterally relieved slot extending parallel to the axis of the plug, which slot may be filled with a protective pressure-transmitting compound and covering the electrical resistance element there located, so that the end surface of the screw and pressure-transmitting filler will be flush with the wall (11) confining the pressure medium.

摘要： A coil sensor excited with alternating current and connected in a circuit for detecting changes in the coil impedance producing a signal exceeding a fixed threshold value in response to the revolution of a wheel with features providing periodic changes in the spacing between the coil and the wheel, has its periphery subdivided into zones where the surface material is alternately thereomagnetic and non-theromagnetic. With a suitable setting of the frequency of the exciting alternating current and a suitable choice of the materials with respect to their eddy current and magnetic induction effect on the inductance of the coil, it is possible to suppress the signal of once per revolution periodicity resulting from wheel eccentricity, bearing wobble or the like.

摘要： To sense pressure within the combustion chamber of an internal combustion engine (ICE), a plug element which already extends into the combustion chamber of the ICE, such as a sparkplug, or a glow plug, has a layer-like resistor applied to a ceramic insulator extending into the combustion chamber, for example, directly on the central insulator of a sparkplug or on the side of a ceramic glow plug bushing or plug element. If applied to a sparkplug then, preferably, the heater is shielded by metallic layers, separated from the metallic shielding layers by insulating layers, of which the top metallic layer preferably is platinum or a platinum-type metal to catalyze combustion of residues which, otherwise, might collect on the top layer and interfere with proper sensor operation. The layer-like sensor and conductive tracks may be of thick film construction; stamp-on printing with flexible printing stamps is suitable to apply the layer-like resistors.

摘要： An apparatus for contactless distance, or travel and/or speed measurement of bodies moving substantially uniformly is disclosed. The apparatus has zones of electrically conductive material which are displaced in synchronism with the body and a measuring transducer disposed at a distance therefrom and spatially fixed, the measuring transducer having a high-frequency alternating current flowing through it. To permit construction of a measuring transducer having large geometric dimensions while detecting narrow electrically conductive zones (10) of attaining measurement signals which are relatively invulnerable to malfunction, the measuring transducer (15) is extended spatially over a multiplicity of zones (10) and has individual, active measuring faces (16) which are interconnected and spatially demarcated. The distance of these active measuring faces (16) from one another, viewed in the direction of movement of the zones (10), corresponds substantially to the distance (b) of adjacent zones (10) and the width of the measuring faces, also viewed in the direction of movement of the zones (10), corresponds substantially to the width (c) of the zones (10).

摘要： An apparatus serving to detect pressure fluctuations in the combustion chamber of an internal combustion engine, including an ionic current sensor, which is exposed to the gases in the combustion chamber and comprises a first electrode and a second electrode, between which a measurement voltage is applied and between which a connecting channel extends from the open combustion chamber into a dead space. In this manner, ionic currents may be detected which are caused by fluctuating pressures in the combustion chamber, particularly when there is engine knocking. Particularly when the geometry of the dead space is adapted to the frequency of the pressure fluctuations which are to be measured, these pressure fluctuations can be detected independently of other, slower pressure variations in the form of a pulsating current which is large when the ion-carrying gas enters the dead space and small when this gas, by now strongly deionized, exits the dead space.
