ABSTRACT:
A sensing system for monitoring a property of an electrically conductive moving element of turbomachinery. The sensing system includes a sensing system housing. A magnetic core is contained within the sensing system housing. A coil is positioned about at least a portion of the core. The coil is electrically connectable to a property data analysis device. A first magnet and a second magnet are positioned about the coil and positionable proximate a moving element of turbomachinery to be monitored. A primary magnetic field is generated by the first and second magnets. When the moving element enters the primary magnetic field a current is induced in the moving element, thus generating a time-variable magnetic field and commensurate voltage signal generated in the coil. The voltage signal is amplified by the magnetic core and provides an indication of a property of the moving element.
