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
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)
