Beschreibung
Zusammenfassung:	A capacitive sensor includes a metal radiator disposed at an extreme end of a sensor assembly. A coaxial electrode is electrically interconnected to the metal radiator. The coaxial electrode has a center conductor, a dielectric around the center conductor, and an outer conductor, the center conductor being in electrical continuity with the metal radiator. An insulator configured to fit adjacent the metal radiator is configured to electrically and thermally isolate the metal radiator from selected electrical and thermal properties in an environment wherein the capacitive sensor probe is disposed. A connector is disposed distal from the metal radiator on the coaxial electrode, a portion of the connector being in electrical continuity with the metal radiator.
