*These notes correspond to the footnote numbers in Table 90:
1. Static/DC measurement types do not have AC (overall) measurement
capabilities. In addition, no alternate path processing is available but
Normal/Advanced CM data acquisition capabilities are available from
main path sources.
2. Eccentricity uses a peak per revolution AC measurement assessment (see
AC Measurement Object). Otherwise eccentricity falls within the
'general' dynamic category regarding capabilities, note 4.
3. Aeroderivative applications types are based on specific processing
requirements.
Generally two channels are deployed per turbine, one with a sensor
positioned at the gas generator (compressor) frame, the other on the
Power turbine frame. The expected input signal is velocity (AV) and
type 83 integrates this signal to displacement, whereas type 80 does not.
The tacho signals are expected to be representative of gas generator and
power turbine shaft speeds. Run a tracking filter from each tacho to
