8.3.1.3 Tracking Filters
The following table defines differences in the tracking filters with versions of the I/O pack.
Item
YVIBS1B
Center frequency -3dB bandwidth correctly matches configuration settings to meet application requirements
Filter roll off Window attenuation increased to -36 dB / octave to meet application requirements
1X / 2X channels Can base phase measurements off of channel 12 or 13
8.3.1.4 Wideband Filters & Velocity Conditioning
The following table defines differences in the Wideband Filters & Velocity Conditioning with versions of the I/O pack.
Item
YVIBS1B
Supported Sensors Velomitors, Seismics & LM Accelerometers with integrated outputs
Maximum octave attenuation -60 dB for all filter configurations
Output of wideband filter Can either be assigned to an RMS calculation or Peak-to-peak algorithm, using VIB_CalcSel
Notes 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
8.3.1.5 CDM Sensors
YVIBS1B adds support for CDM sensors. From the Parameters tab, CDM_scan_period is a selectable scan period for
CDM sensor inputs.
Item
YVIBS1B
Supported sensors Inputs 1-8 support the following:
Bently Nevada CDM Sensor (CDM_BN_ChgAmp)
PCB CDM Sensor (CDM_PCB_ChgAmp)
Maximum octave attenuation -60 dB for all filter configurations
Output of wideband filter Can either be assigned to an RMS calculation or Peak-to-peak algorithm, using VIB_CalcSel
Scan period selection Peak-to-peak or RMS scan period configured by the CDM_Scan_Period parameter.
LM 1x tracking filter support Peak-to-peak output supported for up to 3 frequency selections (Inputs 1-3 only)
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 Vibration Monitoring Application Examples.
