Bently Nevada 3500/40M 176449-01 Proximitor Monitor Module

Description

The Bently Nevada 3500/40M 176449-01 is a four-channel Proximitor Monitor module designed for the 3500 Machinery Protection System. It provides continuous monitoring of critical vibration and position parameters for rotating machinery. The module accepts input signals from Bently Nevada proximity transducers, conditions these signals, and compares them against user-programmable alarm setpoints to ensure equipment safety and reliability.

Features

• Four-channel monitoring capability within a single module.
• Configurable via 3500 Rack Configuration Software for specific monitoring functions.
• Supports multiple measurement types: Radial Vibration, Eccentricity, REBAM (Rolling Element Bearing Absolute Motion), Thrust Position, and Differential Expansion.
• Channel-pair programming allows for two distinct monitoring functions to operate simultaneously on one module.
• Provides comprehensive static values including Direct, Gap, Amplitude, and Phase Lag depending on the selected function.

Applications

• Electric Power: Gas turbines, steam turbines, hydro turbines, and power generation units.
• Oil & Gas: Centrifugal compressors, reciprocating compressors, and high-pressure pumps.
• Heavy Industry: Blast furnace blowers, rolling mill motors, and large-scale fans.
• Mining & Cement: Ball mills, crushers, and heavy-duty gearboxes.
• Water Treatment: Large-scale water pumps and sewage treatment equipment.

Technical Specifications

Installation Guidelines

• Handling: Use proper ESD precautions when handling the module to prevent damage to sensitive electronic components.
• Mounting: Ensure the module is fully seated in the 3500 rack slot and the front panel screws are tightened to ensure proper grounding.
• Wiring: Connect proximity transducers to the corresponding I/O module terminals. Ensure all cable shields are terminated at the designated rack ground to minimize electromagnetic interference (EMI).
• Power: Always power down the rack or ensure the slot is inactive before inserting or removing the module.
• Buffered Outputs: Utilize front-panel coaxial connectors for temporary diagnostic access to raw transducer signals.

FAQs

What is the primary function of the 3500/40M?
It is a machinery protection monitor that processes proximity transducer signals to provide vibration and position data, triggering alarms if parameters exceed defined safety setpoints.

Can I monitor different parameters on one module?
Yes, channels are configured in pairs. You can assign one monitoring function to channels 1 and 2, and a different function to channels 3 and 4.

What software is required for configuration?
The module requires the Bently Nevada 3500 Rack Configuration Software to define channel functions and alarm setpoints.
