Unstable Reading of Accelerometers in Cryogenic Service
Abstract
−
RasGas operates over 100 pieces of cryogenic submersible equipment. Approximately 80 % are on pumping service and the rest on expansion service.
−
These units use two vibration transducers to provide protection and diagnostic capability. The signal from the accelerometer is conveyed to the external signal conditioner (inside field junction box) them to a monitoring system
−
Since commissioning vibration signals tend to be spiky (that is, random in nature) they may OEM recommended alert limits. This may mask potential real problems to the machine.
