Frequently Asked Questions

Q: Is this compatible with legacy 3300 XL sensors?
A: Yes, the 3500/42M accepts standard Bently Nevada proximitor sensors including 3300 XL 8mm and 11mm probes with appropriate extension cables.

Q: What I/O module configuration is included?
A: The 140471-01 I/O module provides 4-channel connectivity. Verify your rack slot compatibility and sensor wiring requirements.

Q: Can I monitor both radial and axial vibration?
A: Absolutely. Configure channels independently for radial displacement (X-Y probes), axial position, or seismic acceleration measurements.

Q: Does this support remote monitoring?
A: When paired with 3500/92 Communication Gateway or 3500/95 Integrator Module, full remote access via Modbus or proprietary protocols is available.
