 note = {Piezoelectric accelerometer sensors which have many advantageous features are widely used in the field of vibration measurement. However, they usually require an amplifier to convert the small charge output to a stable voltage output. This paper describes a newly-developed charge amplifier employing hybrid technics for reducing the weight and size and improving the reliability. These charge amplifiers have had no failures during the time they have been used in the Engine Monitoring System., 資料番号: NALTR0749000, レポート番号: NAL TR-749},
