Abstract: A device for non-contact measurement of current flowing in a wire, cable, or conductor (100) includes a small coil (102) having multiple turns and no ferromagnetic core. The coil (102) is secured to a wand or housing for placing the coil (102) in close proximity to the wire, cable, or conductor (100), whereby a voltage is induced in the coil (102). A readout (105) indicative of the magnitude of the induced voltage comprises a digital display, a series of light emitting device, or a flashing light emitting device having a flash rate proportional to the magnitude of the voltage. A scaling device (103) renders the readout display indicative of the current flow in the wire, cable or conductor (100). The device constructs in a wand or pen-like fashion, with the coil incorporated into the wand. The device may be combined with a voltage sensor to read out relative voltages.

Abstract: A device for non-contact measurement of current flowing in a wire, cable, or conductor includes a small coil having multiple turns and no ferromagnetic core. The coil may be secured to a wand or housing adapted to be used to place the coil in close proximity to the wire, cable, or conductor, whereby a voltage is induced in the coil. A readout indicates the magnitude of the induced voltage, and a scaling device renders the readout display indicative of the current flow in the wire, cable, or conductor. To measure direct current flow, the coil may be vibrated or rotated adjacent to the conductor to cause the magnetic field to induce a voltage in the coil. The readout may comprise a digital display, a series of light emitting devices, or a flashing light emitting device having a flash rate proportional to the magnitude of the voltage. The device may be constructed in a wand or pen-like fashion, with the coil incorporated into the wand. The device may be combined with a voltage sensor to read out relative voltages.
