About
The Mag648 and Mag649 three-axis fluxgate sensors from Bartington Instruments provide low noise magnetic field measurements across a frequency range from DC up to 1kHz. These sensors are characterized by exceptionally low power consumption, typically less than 15mW, and a compact size, making them highly suitable for applications where battery power is critical. Such applications include surveillance systems, remote deployment scenarios, and vehicle monitoring. The Mag648 offers a bandwidth up to 30Hz, while the Mag649® extends this to 1kHz. Both models are available in standard, submersible, and unpackaged versions, offering flexibility for various integration needs. They provide a measuring range of either ±60µT or ±100µT, with a low noise version achieving less than 10pTrms/√Hz at 1Hz. These features make them versatile for a range of demanding magnetic sensing tasks.
