【 摘 要 】

Proper measurement technique in particular during trouble-shooting is important for helium cryogenic facilities. Vibration analysis of rotating components as well as pressure monitoring of helium flow can reveal malfunctioning equipment or could give information on the position and sources of the pressure oscillations, e.g.Thermo-Acoustics or density-wave oscillations. In the present paper, the measurement equipment for monitoring of vibrations as well as pressure oscillations is presented.
