Abstract: Embodiments relate to current difference sensors, systems and methods. In an embodiment, a current difference sensor includes first and second conductors arranged relative to one another such that when a first current flows through the first conductor and a second current, equal to the first current, flows through the second conductor, a first magnetic field induced in the first conductor and a second magnetic field induced in the second conductor cancel each other at a first position and a second position; and first and second magnetic field sensing elements arranged at the first and second positions, respectively.

Abstract: An apparatus for detecting a physical variable has a first sensor unit and a second sensor unit. The first sensor unit detects a physical variable on the basis of a first detection principle. Furthermore, the second sensor unit detects the physical variable on the basis of a second detection principle. In this case, the first detection principle differs from the second detection principle. The first sensor unit the second sensor unit are accommodated in a common housing.
