This report presents vibration data for three positive displacement compressors which will be used to evaluate Microelectromechanical Systems (MEMS) vibration sensors at a later time. The axial, radial and tangential vibration signatures of three compressors were measured under different operating conditions. An open-drive four cylinder compressor's vibration signatures were measured at discharge pressures of 1724 kPa (250 psig) and 2413 kPa (350 psig), with three different drive frequencies. A hermetic scroll compressor's vibration signatures were measured at three drive frequencies with a discharge pressure of 1724 kPa (250 psig), and at one drive frequency with a discharge pressure of 2241 kPa (325 psig). Finally a large, six-cylinder, chiller compressor's vibration signatures were measured with two, four, and six of the cylinders engaged.
