A sensor assembly comprising a base member extending along a longitudinal axis and including a first portion, a second portion, and a twist section positioned between the first portion and the second portion. The sensor assembly further includes a first magnetic field sensor coupled to the first portion, wherein the first magnetic field sensor has a primary sensing direction aligned with the longitudinal axis, and a second magnetic field sensor coupled to the second portion, wherein the second magnetic field sensor is oriented with respect to the first magnetic field sensor such that the second magnetic field sensor has a primary sensing direction aligned with an axis orthogonal to the longitudinal axis.
