Abstract: A turbomachine is provided. The turbomachine comprises a compressor, at least two magnetic bearings provided at opposite ends of a compressor shaft, a motor having a motor shaft, a first electrical cable having a first end, a second end, an internal core section and an outer sheath section with the internal core section and the outer sheath section extending from the first end to the second end, a first connector configured to connect the first end to the first magnetic bearing, wherein the first connector is welded or brazed to the first end to both the internal core section and the outer sheath section, and a second connector configured to connect the second end to the first external connection, wherein the second connector is welded or brazed to the second end to both the internal core section and the outer sheath section.

Abstract: An accelerometer including a metal housing and at least one of an integrated piezoelectric sensor and an integrated electronic piezoelectric (IEPE) amplified sensor within the housing. A metal boot 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 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.
