Inductive Coupling Method for Remote Powering of Sensors
2007
Medeiros, Paul
Means and methods of remotely powering a plurality of sensor coils are described. The plurality of sensor coils can be inductively coupled to a single, primary coil so as to bias the active circuitry of the sensors. The primary and sensor coils can have a separation on the order of inches, such that the sensors can be mounted exterior to a vessel and the primary coil can be mounted interior to the vessel. In some embodiments, the primary coil can be a wire coil. In other embodiments, the primary coil can be a planar coil pattern etched onto a printed circuit board.
