A method for assembling a sensor assembly includes providing a sensing device configured to measure at least one variable. The method also includes at least partially enclosing a magnetic material within an enclosure. At least a portion of the enclosure is manufactured from a material having a permeability that facilitates forming a magnetic field therein. The method also includes coupling the sensing device to a first portion of the enclosure. The enclosure includes at least one second portion that is movable with respect to the first portion of the enclosure such that a magnetic coupling force is induced external to the enclosure to facilitate coupling the sensor assembly to a magnetic surface.
