Linear variable differential transformer arrangements and related methods

A method of operating an arrangement comprising an open-core linear variable differential transformer including a core displaceable in a bore surrounded by a coil arrangement including a primary coil and secondary coils in a displacement range including a linear response range of the linear variable differential transformer, wherein the bore at least extends between a first position at a first end of the coil arrangement and a second end at a second end of the coil arrangement, and wherein a control unit configured to produce output signals corresponding to a plurality of positions of the core in the bore when an excitation current is supplied to the primary coil is provided, characterized in that the displacement range is larger than the linear response range, that the plurality of positions include positions outside the linear response range, and that, using the control unit, the output signals are provided as output signals indicating the plurality of positions of the core in the bore within and outside of the linear response range.

A method of training an artificial intelligence module for an input dataset including at least one of a voltage of a primary coil, one or more voltages of secondary coils, and a temperature of a variable differential transformer to provide output signals corresponding to a plurality of positions of a core in a bore of the variable differential transformer when an excitation current is supplied to the primary coil, said method including providing training data obtained for at least a subset of said plurality of positions.
