|---|
New calculation methodology allowed to minimize the weight and provide low noise level in all frequency band. New system of magnetic compensation along the sensor core was developed for additional noise suppression at frequencies 60 (or 50) Hz (curve 2). Matched low noise amplifier is placed inside the sensor body.
