Noncontact Instrumentation for Turbomachinery Measurements 670944

Discussed and surveyed in this paper are the problems encountered, and techniques used, in making measurement in and on today's high performance, compact design turbomachines. Noncontact measurement of journal position, vibration, displacement and rotational speed are the primary items. However, tip clearance, fluid pressure, etc., and the resultant efficiency and life determining variables can be converted to displacement and measured with these transducers.
