The fluxgate may be used in an access control system.
Disclosed herein is a very low noise fundamental mode orthogonal fluxgate magnetometer.
The fluxgate magnetometer samples the magnetic field at 8 Hz.
The fluxgate may have a considerable length, e.g. several hundreds of metres, and can be arranged in an open loop.
This invention relates to a fluxgate sensor (31) comprising a ferromagnetic core (33), an excitation coil (35) and a pick-up coil (35).
A flux gate sensor (1) having sense windings (15, 17) for providing an output proportional to the strength of an external magnetic field in which the sensor (1) is placed.
The low cost, low permeability three-part magnetic core may be used to accurately sense current using a magnetoresistive sensor or a flux gate based sensor.
The flux gate sensor further comprises a first solenoid coil wound around the first and second end portions and a second solenoid coil wound around the central portion.
