BMS1500 fluxgate transducer is made of an excitation magnetic ring and a control circuit. Under normal conditions, the control circuit generates a fixed excitation current frequency to alternately place the magnetic core at the maximum saturation point. When the measured current flows, the primary current is measured by detecting the symmetry of the saturation point.

The BMS series is suitable for battery monitoring systems that require high accuracy and low offset.
It can realize the isolation measurement between the primary current (high voltage) and the secondary current (12V system).
