Sensors are devices for detecting, collecting and transmitting various kinds of information from the environment. It is the first step of most forms of artificial intelligence and they play more and more important roles in many fields of industry and daily life. Among them, magnetic sensors detect magnetic fields and currents.

  Fluxgate magnetic sensors are especially important in detecting weak magnetic fields. The mechanism of a fluxgate magnetic sensor is based on Faraday’s law of electromagnetic induction. The structure of a fluxgate magnetic sensor mainly consists of excitation windings, core and sensing windings, similar to the structure of a transformer. To date, they have been applied to many fields such as geophysics and astro-observations, wearable electronic devices and non-destructive testing.

  Smagall is a professional leading manufacturer of fluxgate magnetic sensors, cooperating with universities and research institutes home and abroad.

  Compared with other magnetic sensors, fluxgate magnetic sensors have such advantages: 1. high sensitivity 2. high accuracy, 3. high resolution 4. simple and compact structures 5 low noise . What’s more, they can be used in different kinds of environment and even hostile environments, and they have important applications in weak magnetic field measurements.

  Because of their high sensitivity and resolution, fluxgate magnetic sensors are widely used in geophysics and astro-observations. The unmanned aerial vehicles are also used as the new carrier to perform such detection about Earth’s magnetic field apart from the traditional carriers such as a helicopter aeromagnetic surveys or a ground magnetic surveys.
