Three-Axis Fluxgate Magnetometers

Three-axis fluxgate magnetic field sensors are used in many applications, including physics, geophysics, bioelectromagnetics, aerospace and defence.

A three-axis fluxgate magnetometer contains three sensors, in an orthogonal (x,y,z) arrangement. The magnetometer have three outputs, corresponding to the magnetic field strength in the three sensor axes. The total magnetic field strength and direction can be determined by applying simple vector addition.

Bartington Instruments offers a variety of three-axis fluxgate magnetometers with analog voltage outputs.

Mag-03 Three Axis Magnetic Field Sensors
These sensors provide precision measurements of static and alternating magnetic fields in three axes. They are available with full scale ranges of ±70 to ±1000µT, a bandwidth of DC to 3kHz, and in a wide variety of enclosures to suit many different applications. Low noise (<6pT), Standard noise (<10pT) and a Basic version (<20pT) are available.

Mag585 Low EM Radiation Fluxgate Magnetometer
A three-axis magnetometer designed to have near-zero radio frequency emission for MRI applications. It is available in measuring ranges from ±70 to ±1000µT with a bandwidth of DC to 1.5 or 2kHz.
A single-axis version, the Mag592, is also available.

Mag639 Wide Bandwidth Sensor
A three-axis magnetic field sensor offering extended bandwidth to 12kHz. With a ±100uT measuring range, the sensor is intended for use where the Mag-03 frequency response is not sufficient. Typical applications include TDEM (Time Domain Electromagnetics) and MT (Magnetotellurics).
