HSF-100 Orthogonal Standard Fluxgate Magnetometer Sensor

HSF-100 Orthogonal Standard Series Low Noise 3-axis Fluxgate Sensor

Product Overview

The HSF-100 Orthogonal Standard Series is a serialized line of fluxgate sensors featuring a three-axis magnetic orthogonality of ≤±0.1°. Users can directly import the test results into processing software to perform algorithmic corrections on magnetic field data. This series is ideally suited for three-component magnetic field measurements on moving platforms, and customizable station-grade fluxgate sensors are also available.

Quick Selection Guide

1) Noise version

• Super low noise/Low noise: ≤ 6 pT/√Hz @ 1 Hz (Measuring range: ±70uT) /≤ 10 pT/√Hz @ 1 Hz — best for weak anomaly detection

• Standard: ≤ 20 pT/√Hz @ 1 Hz — balanced performance

• Normal: ≤ 30 pT/√Hz @ 1 Hz — cost-effective option

2) Bandwidth option

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

• DC–1 kHz / DC–2 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.

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).
