Preferably, an embodiment of a sensor assembly (200) includes at least a sensor probe assembly (10, 22) providing a plurality of conductive pins (14, 24), a compressible electrically conductive member (202, 302) in electrical communication with the sensor probe assembly, and a signal processing circuit (204, 312) in electrical communication with the compressible electrically conductive member. Preferably, the sensor assembly of the preferred embodiment further includes at least a housing (206, 314) confining said sensor probe assembly, compressible electrically conductive member, and signal processing circuit to form said sensor assembly.
