fluxgate magnetometer - FM-A & FM-D

Sensitive measurement of magnetic fields



The fluxgate magnetometer with single axial Fluxgate-Sensors is available with digital or analog interface (FM-A and FM-D). They are applied for the vectorial determination of magnetic fields and used for the detection of local material failures of electrically conductive materials. The digital sensors (FM-D) of the fluxgate magnetometer are calibrated and easy to use, while the analog sensors (FM-A) of the fluxgate magnetometer are the first choice for tasks where extremely high field resolutions are required. FM-A and FM-D Fluxgate-Sensors can be customized with very low effort to suit various applications.
