ABSTRACT:
The magnetometer assembly according to this invention includes a first coil assembly and a second coil assembly for detecting separate magnetic fields along an axial portion of a torque transducer. The first and second coil assemblies are driven by independently adjustable circuits. Each of the circuits are independently adjustable to adjust the gain that is distributed to each of the first and second coils. This provides for an adjustment and precise alignment of a magnetic field generated by the first coil and the second coil assembly such that external magnetic fields can be cancelled providing increased accuracy and reduced hysteresis effects.
