Sensor
NU.MIK : located approximately 100 meters away from the sources.
Amplitude
- Transmission bandwidth: 5.0150-15.0150 Hz for Soruce No.1
- Transmission bandwidth: 10.0075-20.0075 Hz for Soruce No.2
- Amplitude of vertical velocity within the specified frequency band is evaluated.
- Analysis bandwidth: Source 1
- 05-15 Hz for signal (fundamental mode)
- 10-30 Hz for harmonics (2nd higher mode)
- Analysis bandwidth: Source 2
- 10-20 Hz for signal (fundamental mode)
- 20-40 Hz for harmonics (2nd higher mode)
Data
- Data loss (s) = 3600 (s) - Number of 1 s block in a data file obtained by 'wck'
- Size: Size of data file (byte)
Log
- Status: OK:OK, NL:No log file, S:Stop (No operation), R:Reverse (Opposite) judged by dF.
- dF: Square sum of the difference of Frequency series between actual (monitored) frequency in the Log file and the designed frequency series.
- Log write failure: Number of missing entries (seconds) in a Log file in every 1 hour
- Temperature: Temperature of oil outflow from the source.
- Df: Difference of monitor frequency from carrier ferquency at 00mim 00sec
