First and second coils are disposed coaxially with a gap provided therebetween and are configured to mutually cancel out magnetic fields provided thereby. A receptacle portion that defines a space traversing at least a portion of a magnetic flux produced by the coils is provided, and a magnetic powder is contained in the receptacle portion so as to occupy a portion of the space. The magnetic powder moves within the space, and this movement produces a change in the magnetic flux. This change in the magnetic flux appears in the form of a change in the inductance value.

Methods and systems for a variable differential transformer (VDT) system. The VDT system includes a primary coil to receive a power input, the primary coil balanced on opposing sides by two secondary coils. In response to movement of the core assembly, the secondary coils generate an induced voltage based on a voltage in the primary coil. A control system for measuring an output of the VDT includes a summing circuit to receive an output from two secondary coils. For instance, each of the two secondary coils generate an induced voltage in response changes in position of the core assembly relative to the primary coil and the two secondary coils. A voltage offset circuit adds a voltage offset value to a summing circuit output, which is transmitted to a single rail bias op-amp rectifier circuit.
