HSF-500 Marine Series

  • Description 

    The fluxgate sensors in the marine series are designed for conducting magnetic field measurements underwater. The products feature anti-pressure and anti-corrosion methods to ensure accuracy and protection in sea water. Based on the excellent performance of the traditional fluxgate sensor, the sensors in this series apply non-magnetic, anti-pressure housing and a standard watertight connector. The sensors are divided according to working water depth—300m, 3000m and 7000m, with the larger depth sensors utilizing a titanium alloy shell.

    Features

    • Low noise

    • High sensitivity

    • Excellent linearity

    • Low power consumption

    • Anti pressure 

    • Anti corrosive 

    Application

    • Underwater magnetic field measurement 


  • Sensors in this series are divided into three versions: normal, standard and low noise. In order to meet the power consumption requirements of a device working under water, our company has developed a 5V DC power supply version as well. The power consumption of this version can be as low as 30mW and is convenient for users to control power distribution and management.
