Description
Bently Nevada 3500/40-01-00 Four-Channel Proximitor Monitor
The Bently Nevada 3500/40-01-00, also cataloged as the 3500/40-01-00 Four-Channel Proximitor Monitor, operates as a dedicated signal acquisition module for proximity probe-based shaft vibration and position measurement within the 3500 Machinery Protection System rack architecture. It processes eddy-current probe inputs and converts them into calibrated vibration, axial displacement, and phase reference values through internal channel processing logic.

Eddy-Current Probe Scaling and Multi-Channel Signal Processing
Each channel performs independent eddy-current probe signal conditioning with calibrated gap voltage-to-displacement conversion. Shaft position and vibration signals are linearized against configured sensitivity curves to maintain measurement consistency across all four channels.
The module applies inter-channel isolation logic to reduce signal coupling effects under high-density backplane operation. Phase reference processing is synchronized per channel to support stable rotor orbit reconstruction and comparative vibration trending across multiple measurement points.
Frequently Asked Questions (FAQ)
Q: Do all four channels share the same signal processing path?
A: No. Each channel operates independently with separate conditioning and alarm configuration.
Q: Can the module be hot-swapped during operation?
A: Yes. Hot-swap is supported when the 3500 rack configuration allows redundant power and stable system operation.
Q: Are 4-20 mA outputs individually configurable per channel?
A: Yes. Each channel supports independent scaling and alarm setpoint configuration.
Field Installation Guidelines
Install the module into an assigned slot within the 3500 rack according to system configuration rules. Ensure full seating in the backplane connector to maintain stable signal transfer.
Verify proximity probe wiring integrity and maintain single-point shield grounding to reduce electrical noise coupling. Keep probe signal cabling separated from high-voltage conductors.
After installation, confirm channel LED status indicators and validate configuration parameters through System 1 software before enabling monitoring functions.
