CAS Dataloggers provided its Del-phin Expert Vibro Data Acquisition and Control System (FIG. 2), a vibration monitoring solution, for a refinery relying on a gas turbine-driven generator for power. The facility uses an older generator that has developed vibrations in its shafts and bearings, causing fatigue failures. Turbine failure could be due to bearing wear, failure damage to turbine blades or a number of other factors; therefore, effective fault diagnosis requires analyzing data collected during critical failure win- dows. Technicians were required to establish condition monitoring of vibration signals of the engine's bearings and shafts during operation. Users also needed to acquire process data from the turbine, including temperature, pressure, flow-rate and rotations-per-minute data. Additionally, the generator's manufacturer requested remote-monitoring access to this data for maintenance purposes.
