Abstract
An insulated accelerometer assembly is provided for attachment to a vibrated component. A base has a portion for engagement and connection with the vibrated component and to transmit vibration. An accelerometer senses vibration and is located at least partially within the base. A housing at least partially encloses the accelerometer and inhibits voltage discharge, corona damage, and voltage tracking on the accelerometer. The housing is made of an insulating material and has an interior for the accelerometer. The housing has a plurality of raised fins on the exterior. A mounting cap also inhibits voltage discharge, corona damage, and voltage tracking and secures the housing. The mounting cap is made of insulating material and has an exterior that includes a plurality of raised fins. A cable has an electrically conductive wire and has a shield to inhibit electrical noise.
