- The FOA-200 is a dual-axis fiber optic accelerometer designed to measure vibration amplitudes of high voltage components that are subjected to electrodynamic and mechanical stress, such as stator end-windings. This sensor is suited for operation in hostile environments containing high voltage levels as well as severe electrical and magnetic interference.
