Patent ID: 8051712

Claim:
An insulated accelerometer assembly adapted for attachment to a vibrated component, the assembly including: a base having a portion for engagement with the vibrated component to couple the assembly to the vibrated component and to transmit vibration from the vibrated component to the assembly; an accelerometer disposed at least partially within the base; a housing at least partially enclosing the accelerometer and adapted to inhibit voltage discharge, corona damage, and voltage tracking on the accelerometer, the housing including an insulating material, having an interior with the accelerometer being disposed at least partially within the interior, and having an exterior that includes a plurality of sinusoidally-shaped raised fins non-engaged with other structures and providing increased effective surface length along the housing to inhibit electrical tracking; a mounting cap adapted to inhibit voltage discharge, corona damage, and voltage tracking on the accelerometer and having a portion engaged with the base to secure the housing relative to the base, the mounting cap including an electrically insulating material, and having an exterior that includes a plurality of sinusoidally-shaped raised fins non-engaged with other structures and providing increased effective surface length along the mounting cap to inhibit electrical tracking; and a cable having at least one electrically conductive wire and a shield to inhibit influence on the wire, the wire being operatively coupled to the accelerometer and extending within the shield.
