<p>A proximity sensor includes a sensing element having a sensing tip, wherein the tip has a conductive shield substantially surrounding at least a circumferential portion of the sensing element,, and preferably also the sensing tip, the conductive shield having electromagnetic discontinuities that allow an electromagnetic field to pass therethrough. The discontinuities may be tailored to provide desired electromagnetic field characteristics. The conductive shield provides physical protection to the tip, allowing the sensor to be used in particularly hostile environments such as in hot areas of gas turbine engines. The sensor may typically be an eddy current sensor.</p> |
