8.3.2 Vibration Monitoring Firmware

The following subsections provide details for common firmware features using in vibration monitoring applications. For
application-specific firmware use cases and procedures, refer to the section
236 GEH-6855_Vol_II
YVIBS1B
-3dB bandwidth correctly matches configuration settings to meet application requirements
Window attenuation increased to -36 dB / octave to meet application requirements
Can base phase measurements off of channel 12 or 13
YVIBS1B
Velomitors, Seismics & LM Accelerometers with integrated outputs
-60 dB for all filter configurations
Can either be assigned to an RMS calculation or Peak-to-peak algorithm, using
Peak-to-peak algorithm and RMS calculation use a Scan time of data. Update rate is equal Frame
Rate.
ISO for Vibration calls for RMS calculations
YVIBS1B
Inputs 1-8 support the following:
Bently Nevada CDM Sensor (CDM_BN_ChgAmp)
PCB CDM Sensor (CDM_PCB_ChgAmp)
-60 dB for all filter configurations
Can either be assigned to an RMS calculation or Peak-to-peak algorithm, using VIB_CalcSel
Peak-to-peak or RMS scan period configured by the CDM_Scan_Period parameter.
Peak-to-peak output supported for up to 3 frequency selections (Inputs 1-3 only)
