Abstract :
In the paper the operating principle and basic parameters of a ring-core flux-gate based compensating transducer to measure a static magnetic field is described. A theoretical analysis has been made and an approximate transduction function has been derived. The presented results of tests carried out on a transducer model testify that the device in question is distinguished by a high and easily adjustable sensitivity and a linear transduction characteristic.
