Claim 12:
13. A method of sensing, comprising the steps of:
providing an axle assembly including a sensor assembly configured to sense a parameter of a movable component of the axle assembly, wherein the movable component is a differential case, wherein the axle assembly includes a differential assembly, and wherein the differential assembly is supported within a housing of the axle assembly, wherein the sensor assembly includes a first wire coil disposed within the housing and a second wire coil that is spaced apart from the first wire coil and disposed within the housing, wherein the first wire coil is in electrical communication with a first electrical circuit including a signal device coupled to the housing, and wherein the second wire coil is in electrical communication with a second electrical circuit including a sensing device for measuring the parameter of the differential case;
generating a magnetic field between the first wire coil and the second wire coil;
transmitting a further electrical current from the first electrical circuit to the second electrical circuit using the magnetic field;
measuring the parameter of the movable component utilizing the sensing device of the second electrical circuit;
transmitting an electrical current varied as a function of the parameter of the differential case from the second electrical circuit to the first electrical circuit using the magnetic field; and
generating an output signal indicative of the parameter of the differential case using the signal device of the first electrical circuit.
