摘要： An arrangement is provided for measuring the field strength of a magnetic field, or measuring field, by an angle sensor. The angle sensor is aligned with the field lines of the measuring field at the position of the field strength of the measuring field, or measuring position. A device for generating a magnetic auxiliary field at the measuring position is also included. The angle sensor can be impressed with the magnetic auxiliary field in a predeterminable field strength and in a direction deviating from that of the field lines of the measuring field at the measuring position, forming a resultant magnetic field with a field line direction. The field line direction is measured by the angle sensor as a measure of the field strength of the measuring field. The arrangement is reliable, suitable for measuring high magnetic field strengths, has no reactive effects, and permits measurements with magnetoresistive angle sensors.

摘要： An electrical circuit finder has a transmitter which is plugged into one of the circuits of a building's electrical system and a receiver which is used to identify other elements of the circuit such as a circuit breaker, fuse, switch, electrical device or outlet. The transmitter induces in the circuit a high frequency current signal which is modulated at a lower frequency. The receiver, including a sensor wand and a receiver housing, is tuned to inductively detect the high frequency when placed in the magnetic field of the circuit and to produce visual and audible signals to the user which vary in intensity according to the detected signal. The user can thereby use his or her visual and/or audio senses to associate a circuit element proximate to the receiver with the circuit element connected to the transmitter.

摘要： A method and an apparatus for the detection of the current distribution in at least one conductor (W1, W2) of an electric machine are specified, which indirectly permit, in a simple manner, the metrological determination of said distribution. The conductors or Roebel bars (W1, W2) are arranged in a slot (4) of a stator laminate stack (3) of the electric machine and each has a plurality of mutually electrically insulated and transposed conductor elements (W1nl, W1nr; W2nl, W2nr). A probe holder (6) which can be displaced radially with regard to the electric machine and contains, in recesses, 2 magnetic field probes (M1, M2) with a predeterminable center-to-center distance (d) is provided, adjacent to these conductors (W1, W2) in a probe channel (17) within the slot (4). The magnetic transverse field within the slot (4) is measured using said probes. For the purpose of determining the electric current distribution, this magnetic transverse field strength is combined, by multiplication, with a width (b) of the slot (4).

摘要： A probe operable in conjunction with an electrometer having a high input impedance to provide an instrument for measuring air ion flux density. The probe structure is such that its presence in the atmosphere in which a measurement is being carried out will not give rise to perturbations in the localized electric field and therefore has no perceptible effect on the accuracy of measurement. The probe is constituted by a metal target to which the ions give up their charge, the target being supported at the end of a barrel of dielectric material by a conductor attached thereto and extending axially through the barrel to a contact at the rear of the barrel which is connected to the line of a shielded coaxial cable which couples the target to the input terminal of a grounded electrometer, the shield of the cable also being grounded. The surface of the barrel is coated with a layer of semi-conductive material that makes contact at the lower end of the barrel with the grounded cable shield. The semi-conductive layer on the barrel surrounding the target conductor therein provides a controlled leakage path extending between the target and the grounded cable shield that approximates the characteristics of the atmosphere and the input impedance of the electrometer whereby the presence of the probe in the atmosphere introduces substantially no discontinuity in the localized electric field.

摘要： An ion counter for measuring the density of atmospheric ions has two basic sections, the electrometer, which is of a conventional type, and the collector. An improved collector is provided having two collector plates in electrical contact, mounted either side of a polarizing plate to form a double channel cell having two air passages. The polarizing plate and the collector plates are tightly secured to insulators so as accurately to maintain the spacing between the plates.

摘要： Disclosed is a method for the nondestructive testing of weld clusters having at least a first and a second weld joining metal elements including the steps of injecting a current into one of the elements from a suitable source by contacting each of the elements with a current probe therefrom. A first current density is then measured between the current probe and the first weld and a second current density is measured between the current probe and the second weld and the first current density is then compared with the second current density so as to determine the relative quality of said welds.

摘要： An electrical unit for sensing a steady magnetic field intensity produced by the flow of direct current is mounted in a carriage a fixed distance from the running surface of the carriage and is electrically connected in circuit with indicating means, which may be visual means, such as a light, or an audible alarm or both, energized in response to the sensing of a magnetic field of intensity greater than is produced by electrical current flow of up to a predetermined normal maximum amperage. The carriage is preferably of sled formation adapted to be pushed or pulled across a multitude of electrode suspension bars arranged in series along electrolytic cells in an electrolytic tank house, which bars serve to conduct current to the electrodes. The sensing unit is advantageously a magnetodiode, but may be any one of a number of possible alternatives, e.g. reed relays, electrically connected in suitable control circuitry.
