    摘要: Current is sensed in a physically large conductor by a pair of noncontacting, magnetically responsive corrected current sensors. The sensors each have a preferred magnetic sensing axis. A holding arrangement, which may be a printed-circuit board, holds the two current sensors with their axes spaced apart and parallel, to thereby define a sensing plane. The holding arrangement is placed near the conductor in which current is to be sensed, with the sensing plane parallel to a tangent to outer surface of the conductor. The current in the conductor is represented by the sum of the signals of the sensors. In the case of alternating current and sensors responsive to the absolute value of magnetic field, the summing includes subtraction.

    摘要: An alternating current sensor includes a conductive pipe and a cylindrical-shaped conductive element preferably partially surrounded by the pipe. The pipe is substantially concentric to the conductive element and a conductor electrically connects a pair of corresponding ends of the pipe and conductive element to form a connected conductive path through the sensor. The pipe and the conductive element are spaced apart a predetermined radial distance to form a magnetic field in the space between the pipe and the conductive element during current flow along the connected conductive path. A flux sensor, such as an air-core coil, senses changes in magnetic flux over a sense region situated in the space between the pipe and the conductive element. A transformer having a saturable magnetic core is responsive to a magnetic field over a transformer region for generating a predetermined level of electrical current which can be used for safely powering various electrical circuits associated with the current sensor.

    摘要: A noninductive shunt current sensor includes a cylindrical-shaped conductive element and a concentric conductive pipe electrically connected at one end by a conductor, such as a washer. Except for the conductor, the pipe and conductive element are electrically isolated from each other by insulation, such as a polyimide or an air-gap. Sensing wires are electrically connected to contact points, each contact point being located on either the inner surface of the inner pipe or the outer surface of the outer pipe. The wires pass through a space where the magnetic field is substantially null, thereby minimizing any mutual coupling effects. A magnetic core and a coil can be situated between the pipe and the conductive element to provide an electrical self-power capability to the noninductive shunt current sensor.

    摘要: An optical temperature compensation system for spectral modulation sensors includes a light director for receiving excitation light, a spectral modulation sensor for receiving and modulating a first portion of the excitation light from the light director, and an optical processing component for receiving and determining properties of a second portion of the excitation light from the light director and the modulated first portion of the excitation light. The optical processing component comprises a dispersive element for dispersing the second portion of the excitation light and the modulated first portion of the excitation light and a charge transfer device for converting the dispersed portions of light into electrical signals. A digital signal processor calculates a detected ratio of the electrical signals which compensates for inaccuracies in measurement due to source temperature variations.
