HSF-300 Band Pass Series Fluxgate Magnetometer Sensor

HSF-300 Bandpass Series 3-axis Fluxgate Sensor

Product Overview

The HSF-300 Bandpass Series is a three-axis fluxgate sensor designed specifically for measuring magnetic fields within a targeted frequency range. This series is highly customizable，both the start (lower) and cut-off (upper) frequencies can be adjusted based on specific customer requirements. Furthermore, key parameters such as sensitivity, linearity, and noise are finely tuned to ensure the sensor's overall performance is fully optimized for its intended application.
