An accelerometer (14) includes a metal housing (16) and at least one of an integrated piezoelectric sensor and an integrated electronic piezoelectric (IEPE) amplified sensor within the housing. A metal boot (36) extends from the housing and a plurality of sensor wires extends from the sensor into the boot. The accelerometer also includes a metal cable sheath (38) connected to the boot having a plurality of cable wires insulated by a metal oxide powder contained by the sheath. At least one of the plurality of sensor wires is connected to at least one of the plurality of cable wires within the boot. The housing, the boot, and the metal cable sheath provide a sealed enclosure for the at least one sensor, the plurality of sensor wires and the plurality of cable wires.
