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.
Low power consumption
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.
（1）Low noise version：≤6pTrms/Hz1/2@1Hz
（Note: This is the noise parameter of the sensor with the measuring range less than 100µT ）
High voltage power supply: ±12V～±15VDC，±10V analog voltage output, power consumption = 0.4W;
Low voltage power supply：±3.3V～±5VDC, ±2.5V analog voltage output, power consumption = 30mW;
Standard housing：30x30x120mm, for operation at 300m depth, watertight joint;
Anti pressure housing: 36x36x130mm, for operation at 3000m depth under water, watertight joint.
