Three-Axis Fluxgate Magnetometers

Bartington Instruments offers an extensive range of three-axis magnetometers. These are suited to many different applications and operating environments, including general purpose, low power, digital, and specialist.

General Purpose

Mag-03 Our most versatile sensor, it offers measuring ranges from ±70µT to ±1000µT, a bandwidth up to 3kHz, and noise levels down to less than 6pTrms/√Hz at 1Hz. It is available in a range of versions. This sensor is ideal for use in applications where high precision magnetic field measurements are required.

Mag-13 This is the lowest noise sensor available. It has noise levels below 5pTrms/√Hz at 1Hz, measuring ranges from ±60µT and ±100µT, and a bandwidth up to 3kHz. These sensors are environmentally sealed and incorporate a test coil and temperature sensor.

Mag690 This lower cost general purpose sensor is available with measuring ranges from ±100µT to ±1000µT, and bandwidth of 1kHz. It has noise levels from 10 to < 20pTrms/√Hz at 1Hz. Its performance and low cost make this sensor suitable for a wide range of OEM applications.

Mag639 This is the widest bandwidth magnetometer available, with a bandwidth of 12kHz. It offers noise levels from 10 to < 20pTrms/√Hz at 1Hz, and a measuring range of ±100µT. Designed for use in TDEM (Time Domain Electromagnetics) for UXO (unexploded ordnance) detection, but also has uses in environmental monitoring for EMC purposes.

Mag612 This low cost, two-part sensor, comprises a compact fluxgate probe and separate electronics connected by a cable up to 3 metres in length. It has noise levels from > 10 to < 20pTrms/√Hz at 1Hz. This probe can be supplied on its own, or with the electronics circuit design, which assists probe integration into your own design.

Mag619 This compact probe is supplied with a separate electronics connected by a cable of 1 metre. It has noise levels from > 10 to < 50pTrms/√Hz at 1Hz. This probe can be supplied on its own, or with the fluxgate magnetometer circuit design, which assists probe integration into your own design.

Low Power

Mag648/649 These low power sensors are available with measuring ranges of ±60µT or ±100µT, and offer noise levels from > 10 to ≤ 20pTrms/√Hz at 1Hz. The Mag649 is available with bandwidth of 1kHz. Both models are available with a variety of enclosures including submersible. They are especially suited to battery powered and surveillance applications.

Mag651 This unpackaged, low cost, low power sensor has a measuring range of ±60µT, and noise range level from 10 to < 20pTrms/√Hz at 1Hz. It is especially suited to battery powered and surveillance applications.

Digital

Mag658 This unpackaged digital magnetometer has a resolution of 24-bit, measuring range of ±524µT, and includes an RS422 interface. It incorporates three-axis accelerometers to indicate sensor orientation.

Handheld Gaussmeters

TFM1186/THM1176 These handheld fluxgate and Hall Effect magnetometer gaussmeters offer a measuring range from ±100µT to ±20T, a bandwidth of 1kHz, and resolution starting at 4nT. Desktop versions are also available.
