An electronic expansion valve for an HVAC system and method of operating the same is provided, wherein the EEV comprises a longitudinal displacement axis, an obturator, a rotor comprising a magnet, a first sensor disposed along the longitudinal displacement axis at a first longitudinal location and configured to output a first voltage, and a second sensor disposed along the longitudinal displacement axis at a second longitudinal location and configured to output a second voltage, wherein the first longitudinal location is longitudinally displaced from the second longitudinal location along the longitudinal displacement axis, and wherein the position, direction of movement, linear speed, angular speed, and angular displacement of an obturator may be determined as a result of the first voltage output from the first sensor and second voltage output from the second sensor. |
