Low power flux-gate magnetometer LEMI-031 for the monitoring of 3-components of the magnetic field vector in land conditions

Description

Low power flux-gate magnetometer LEMI-031 is intended for the monitoring of three components of the magnetic field vector in land conditions. The instrument is specially designed for battery powered applications and has differential outputs for easy coupling with analogue to digital converter. Several know-hows are used to keep the power consumption of LEMI-031 magnetometer at world lowest level.
