Eddy-Current Probe Scaling and Gap Voltage Validation
The module processes eddy-current probe inputs using calibrated 200 mV/mil scaling for displacement reconstruction. Gap voltage validation is referenced against nominal -10 VDC center position behavior, enabling stable shaft centerline tracking. Cross-channel comparison logic is applied to reduce measurement drift between X and Y vibration planes while maintaining separation of radial vibration and DC gap components.
Frequently Asked Questions
Q: Does the module support hot-swap replacement in a live rack?
A: Hot-swap is dependent on backplane design. Electrical insertion is allowed only when rack supports live module exchange; field terminals must remain isolated during removal.
Q: What is the backplane loading impact per module?
A: The module draws approximately 2 W nominal power; backplane loading is determined by total rack configuration and power supply capacity.
Q: Can firmware or configuration be migrated between identical units?
A: Configuration parameters can be replicated, but calibration must be verified due to probe scaling and channel-to-channel alignment requirements.
Field Installation Guidelines
-
Install only in compatible Bently Nevada 3300 rack chassis
-
Maintain continuous coaxial shielding from probe to monitor input terminal
-
Ensure probe gap voltage stabilizes near calibrated center (-10 VDC reference region) before enabling alarms
-
Avoid routing proximity probe wiring alongside VFD or high voltage conductors
-
Verify XY channel polarity alignment before enabling vibration logic
-
Confirm relay configuration state (Alert/Danger) prior to operational service
-
Ensure proper grounding of rack chassis to reduce signal noise coupling
