Fluxgate magnetometer sensor measures magnetic field value by nonlinear relationship between magnetic induction intensity and the measured magnetic field intensity of high permeability magnetic core under saturation excitation of alternating magnetic field. Fluxgate magnetic sensor can measure static magnetic field and alternating magnetic field with high precision, and can measure three perpendicular magnetic field components at most at the same time. HSF-100 fluxgate magnetometer sensor is especially suitable for vector measurement of weak magnetic field and high resolution measurement of magnetic field, such as geomagnetic measurement, geological exploration, material nondestructive testing and space magnetic field measurement with the characteristics of high resolution, good linearity, wide frequency response and low noise. This magnetic sensor adopts waterproof design, and can be used in underwater and outdoor environment.
Fluxgate magnetic sensor HSF-100 model is a 3 axis fluxgate magnetometer sensor with orthogonality ≤±0.2° and low noise <6pT. With high resolution and light weight, 3 axis fluxgate magnetometer sensor was widely used for magnetic anomaly measurement as detector and magnetic survey measurement equipment. HSF-100 fluxgate magnetometer sensor is suitable for the 3 axis magnetic field measurement based on moving platform, and the station fluxgate sensor is customized. With strong R&D team, SMAGALL is committed to develop high sensitivity sensors to contribute to geophysical surveys in the geomagnetic field industry. After 23 years of development, SMAGALL fluxgate magnetometer sensors are comparable to advanced foreign products and have been well received by users who are looking for mag03 sensors, FG sensors, bartington instruments
