Abstract
The present invention related to devices and methods for using ferrite alignment keys in wireless remote sensor assemblies. In one aspect, the invention provides wireless resonant sensor assemblies comprising a pick-up coil, a ferrite alignment key positioned in and extending from the pick-up coil, and wireless resonant sensor having a receiving element wherein the pick-up coil and the wireless resonant sensor align upon insertion of the ferrite alignment key into the receiving element. The ferrite alignment key may also be part of a resonant sensor such that insertion of a pick-up coil into a receiving element of the alignment key results in a configuration where the alignment key is positioned in and extended from the pick-up coil. Methods of measuring one or more parameters of a monitoring system are also provided. The insertion of the ferrite alignment key aligns the pick-up coil and wireless resonant sensor thereby increasing sensing of the wireless resonant sensor by the pick-up coil.
