HSF-600 Aviation Series Fluxgate Magnetometer Sensor

Lightweight 3-axis fluxgate sensor designed for UAV and airborne magnetic survey, offering low noise, wide bandwidth options, and waterproof packaging.

Typical Applications

• UAV / airborne magnetic survey and aeromagnetic mapping

• Geological exploration and field magnetic measurement on moving platforms

• Environmental magnetic field monitoring in outdoor conditions

• Mobile magnetic measurement where low noise and lightweight sensor are required

Is HSF-600 suitable for your application?

• Best for UAV and airborne magnetic survey where weight and size are critical

• Suitable for low-field measurement within the Earth magnetic field range (e.g., ±70 / ±100 μT options)

• Choose the “Low noise” version when detecting weak anomalies is important

• Choose DC–1 kHz or DC–3 kHz bandwidth when higher-frequency magnetic variations are of interest

• Not intended as a complete magnetometer system (this page is sensor only); DAQ / GPS / recording modules are available separately

Quick Selection Guide

1) Noise version

• Low noise: ≤ 6 pT/√Hz @ 1 Hz — best for weak anomaly detection

• Standard: ≤ 10 pT/√Hz @ 1 Hz — balanced performance

• Normal: ≤ 20 pT/√Hz @ 1 Hz — cost-effective option

2) Bandwidth option

• DC–100 Hz — typical low-frequency survey work

• DC–1 kHz / DC–3 kHz — when your application requires higher bandwidth

3) Range & sensitivity (examples)

• ±70 μT (high sensitivity) / ±100 μT (general) / ±250 μT (higher range)

*Note: noise increases when the measurement range increases.

UAV Survey Note

For mineral exploration surveys, typical flight height is 20–30 m AGL with ~50 m line spacing.

Data processing tools such as Oasis montaj are commonly used, and noise filtering should be considered during processing.

Product Packaging Options

• Standard package: 30×30×120 mm, 7-core waterproof connector (IP68), ~220 g

• Non-magnetic interface package: 28×32×82 mm, D-type 9-pin non-magnetic connector, ~150 g

Recommended: choose the non-magnetic interface package when connector magnetism and platform interference are critical (e.g., UAV payload integration).
