HSF-500 Ocean Series Fluxgate Magnetic Sensor

Product Overview
HSF-500 submarine three axis fluxgate sensor is a product with pressure resistance and seawater corrosion resistance developed by Xi’ an Huashun according to the requirements of underwater magnetic measurement. The series fluxgate sensor is packed by non-magnetic pressure resistant shell to ensure the excellent performance of the sensor. The connectors will be industry standard watertight ones. According to the working water depth, it is divided into 300 meters, 3000 meters and 7000 meters, of which 3000 meters and 7000 meters product shells are made of titanium alloy, and the fluxgate sensor with cable type and mooring type can be customized.

Product Features
Low noise, high sensitivity, good linearity, low power consumption, pressure resistance and seawater corrosion resistance

Application
Underwater submarine magnetic survey
