Abstract

According to some embodiments, system and methods are provided, comprising an installed product including a drive shaft; a magnetostrictive sensor having a sensor probe comprising: a substrate; a drive coil operative to receive a drive current and to emit a magnetic field through the drive shaft, wherein the drive coil is mounted on the substrate; one or more sense coils operative to receive the magnetic field and to transmit a signal based on the received magnetic field, wherein the one or more sense coils are mounted on the substrate; and wherein the magnetic field is emitted from the drive coil in a transverse direction to a radius of the drive shaft. Numerous other aspects are provided.
