Hardware Specifications

Rotor Dynamics and Cross-Talk Suppression

The monitor integrates rotor dynamics evaluation by processing casing expansion signals from LVDTs. Buffered outputs provide raw voltage signals for diagnostic analyzers. Internal conditioning suppresses cross-talk between channels, ensuring accurate comparative displacement tracking.

Frequently Asked Questions

Q: What recorder outputs are available? A: The module supports both 4-20 mA and 1-5 VDC proportional outputs for PLC/DCS integration.

Q: How are alarm setpoints configured? A: Alert and Danger thresholds are set via internal jumpers, providing deterministic relay switching.

Q: Can buffered outputs be used for diagnostics? A: Yes, front-panel coaxial connectors deliver unfiltered raw signals for analyzer troubleshooting.

Field Installation Guidelines

• Insert into a single-slot rack position with full connector engagement.
• Ensure LVDT cabling is shielded and grounded at the rack end only.
• Route signal wiring separately from high-voltage conductors to minimize induced noise.
• Validate displacement calibration during commissioning using reference displacement blocks.
• Configure alarm setpoints internally before system startup.
