Three-Axis Fluxgate Magnetometers

Bartington Instruments offers an extensive range of three-axis magnetometers suited to different applications and operating environments. This includes general purpose, low power, digital and specialists fluxgate magnetic field sensors.

General Purpose:

Mag-03 The most versatile sensor, it offers measuring ranges from ±70µT to ±1000µT, bandwidth up to 3kHz, a range of enclosures including submersible as well as noise levels down to < 6pTrms/√Hz at 1Hz. This sensor can be used for most applications where high precision magnetic field measurements are required.

Mag-13 The lowest noise sensor available, it has noise levels down to < 4pTrms/√Hz at 1Hz. With measuring ranges from ±60µT and ±100µT and bandwidth up to 3kHz. Range of enclosures available, all environmentally sealed and inclusive of a test coil. This newer generation of sensors offers improved performance for very high accuracy measurements.

Mag690 Lower cost general purpose sensor with measuring ranges from ±100µT to ±1000µT and bandwidth of 1kHz. It has noise levels >10 to < 20pTrms/√Hz at 1Hz. It's performance and low cost make the sensor suitable for a wide range of applications including active magnetic field cancellation.

Mag639 The widest bandwidth magnetometer available, with bandwidth of 12kHz. It also offers noise levels >10 to < 20pTrms/√Hz at 1Hz, and a measuring range of ±100µT. Designed for use in TDEM (Time Domain Electromagnetics) for UXO detection, the sensor is also used for environmental monitoring for EMC purpose.

Mag612 Low cost, two-part sensor, consisting of compact fluxgate probe and separate electronics connected by a cable up to 3 metres. It has noise level >10 to < 20pTrms/√Hz at 1Hz. Probe alone available together with fluxgate magnetometer circuit design available to help probe integration into their own design.

Mag619 The smallest fluxgate probe we currently supply, it is supplied with a separate electronics connected by a cable of 1 metre. It has noise level >10 to < 50pTrms/√Hz at 1Hz. Probe alone available together with fluxgate magnetometer circuit design available to help probe integration into their own design.

Low Power

Mag648/649 Low power sensors with measuring ranges of ±60µT or ±100µT, low noise option to ≤10pTrms/√Hz at 1Hz. Available with bandwidth of 1kHz (Mag649 only), a range of enclosure, including submersible are available. Typically suited to battery powered or surveillance applications.

Mag651 An unpackaged, low cost and low power, sensor with measuring ranges of ±60µT and noise range level >10 to < 20pTrms/√Hz at 1Hz. Typically suited to battery powered or surveillance applications.

Mag650 An unpackaged low power sensor with noise specifications >10 to ≤50pTrms/√Hz at 1Hz. It's design allows for integration in compact cylindrical enclosure together with battery cells.

Digital

Mag658 Unpackaged digital three-axis magnetometer with a resolution of 24-bit, and RS422 interface. It incorporates three-axis accelerometers to indicate sensor orientation. Measuring range of ±524µT.

Low Radiation

Mag585 A three-axis magnetometer with low emitted radio-frequency radiations. Measuring ranges from ±70µT to ±1000µT and with bandwidth up to 2kHz. Typical applications include magnetic field measurement around permanent magnet MRI.

Handheld Magnetometers

TFM1186/THM1176 Handheld Fluxgate and Hall Effect magnetometers. With measuring ranges from ±100µT to ±20T, and bandwidth of 1kHz. Resolution starts at 4nT. Desktop versions are also available.
