Definitions

  • the construction of the sensor is significantly simplified and this will reduce manufacturing complexity and cost of producing the sensor.
  • the fluxgate sensor is implemented using PCB technology or magnetics on silicone technology, the number of metal layers required is reduced thereby reducing manufacturing complexity and cost.
  • additional layers equivalent to the number of layers of existing devices could be provided in order to provide more turns for each of the coils and thus reduce power consumption and improve sensitivity of the fluxgate sensor - A -
  • some of the common coils sections are arranged mutually perpendicular to each other.
  • the senor is excited with a sine wave excitation current.
  • Figure 1 is a diagrammatic representation of a fluxgate sensor known in the art
  • a common coil comprising one or more excitation coils and/or one or more pick-up coils
  • the common unitary coil is used as both the excitation coil and the pick-up coil.
  • the core 33 is a so-called racetrack core having a pair of longitudinal sections 45, 47 and a pair of curved sections 49, 51.
  • One half 37 of the common coil 35 is wrapped around one of the pair of longitudinal sections 47 and the other half 39 of the common coil 35 is wrapped around the other longitudinal section 47 of the racetrack core 33.
  • FIG. 10 there is shown an alternative construction of fluxgate sensor indicated generally by the reference numeral 151 in which like parts have been given the same reference numerals as before.
  • the core 133 is similar to that shown in Fig. 9.
  • a single common coil 153 is provided and wound around all legs of 141a-141f of the core 133.
  • a current source 155 provides an alternating current to the common coil 153.
  • the voltages of the coil sections surrounding opposing leg pairs 141a and 141 b, 141c and 141d, 141e and 141f respectively are measured and summed together to determine the magnetic field in the "X" plane, "Y" plane and "Z” plane respectively.
  • a single common coil is required to obtain the magnetic field information. It is envisaged that the common coil will be divided so that a sixth of the total coil turns will be wound around each of the legs 141a - 141f of the core 133.

Abstract

Cette invention concerne un capteur à sonde magnétométrique (31) qui comporte un noyau ferromagnétique (33), une bobine d'excitation (35) et une bobine de capture (35). La bobine d'excitation et la bobine de capture sont mises en œuvre à l'aide d'une bobine commune (35) au lieu d'utiliser des bobines séparées pour la bobine d'excitation et la bobine de capture. Par la fourniture d'un tel capteur à sonde magnétométrique, la construction du capteur est simplifiée, réduisant ainsi la complexité de fabrication et le coût. En variante, par la mise en œuvre du capteur à sonde magnétométrique dans un mode utilisant le même niveau de complexité que des configurations connues, par exemple avec le même nombre de couches avec des motifs de bobine, la sensibilité et l’efficacité sonore des capteurs sont améliorées par rapport à des configurations connues.
