Description
Description
The Bently Nevada 3500/40-03-01 Proximitor Monitor is a four-channel module designed for the 3500 Series Machinery Protection System. This module conditions input signals from proximity transducers to provide continuous, high-integrity monitoring of critical machinery parameters including shaft radial vibration, thrust position, differential expansion, eccentricity, and REBAM (Radial Eccentricity and Blade Amplitude Measurement). The 03-01 configuration ensures compatibility with standard Bently Nevada proximity probe systems.
Features
- Four independent monitoring channels for comprehensive machine protection.
- Programmable Alert and Danger setpoints for customized alarm logic.
- Integrated 4-20 mA recorder outputs for each channel to interface with external control systems.
- Front-panel LED indicators providing real-time status for OK, Bypass, Alert, and Danger conditions.
- Buffered transducer outputs available on the front panel for advanced diagnostic analysis.
- Designed for continuous online monitoring in compliance with API 670 standards.
- Fully configurable via the Bently Nevada 3500 Rack Configuration Software.
Applications
This module is essential for protecting critical rotating machinery, such as steam turbines, gas turbines, centrifugal compressors, and large pumps. It is widely used in power generation, oil and gas, and petrochemical facilities to detect mechanical faults before they lead to catastrophic failure.

Installation Guidelines
- Ensure the 3500 rack is powered down before inserting or removing the module.
- The module is designed for standard 3500 rack mounting; ensure the card is fully seated and the front panel screws are tightened to maintain proper grounding.
- Use shielded twisted-pair cabling for all transducer inputs to minimize EMI/RFI interference.
- Follow proper ESD handling procedures when touching the module circuitry.
- Verify that the I/O module configuration matches the installed transducer type and sensitivity settings in the 3500 software.
FAQ
What is the primary function of the 3500/40-03-01?
This module acts as the interface between proximity probes and the 3500 rack, converting raw transducer signals into usable vibration and position data for machinery protection.
Can this module be configured for different types of measurements?
Yes, the 3500/40 is highly versatile and supports multiple measurement types including radial vibration, thrust, and expansion, which are selected and configured via the 3500 Rack Configuration Software.
