A sprayer hose assembly including an inner tube, an outer sheath, and an energy conducting conduit extending along the outer sheath. The eddy current heating reduction system includes electrical insulation between the at least two magnet assembly components, and includes at least one of the at least two magnet assembly components having a divided current loop area at least two spaced subsections. The detected radiation is AC-coupled to isolate components relating to oscillations of the target object from components relating to ambient radiation, e.
