Abstract

A sensor includes a housing, a central sensor electrode assembly, an insulating member, and a trace. The central sensor electrode assembly is coupled to a supply side of a voltage source. The insulating member is coupled between the housing and the central sensor electrode assembly. The insulating member circumscribes a section of the central sensor electrode assembly. The trace is coupled to the insulating member and circumscribes the section of the central sensor electrode assembly. The trace directs at least a portion of leakage current away from a voltage ground offset on an opposite side of the central sensor electrode assembly.
