Applications and Industry Context

Rotating machinery such as turbines, compressors, and pumps forms the backbone of many industrial operations. Unplanned failures can have dramatic consequences, including costly downtime, safety hazards, and equipment damage. The Bently Nevada 3500/42M 176449-02 is engineered to prevent such failures by providing real-time monitoring of vibration and position signals.

Industries benefiting from this module include:

• Oil & Gas: Continuous monitoring of compressors, pumps, and turbines in upstream, midstream, and refining operations.
• Power Generation: Steam and gas turbines, generators, and associated rotating machinery are monitored to prevent overspeed and excessive vibration.
• Chemical & Petrochemical: Critical rotating equipment is protected against shaft misalignment, imbalance, and bearing wear.
• Mining & Heavy Industry: Crushers, mills, and kilns require continuous vibration monitoring to maintain uptime and safety.

By using the 3500/42M 176449-02, operators gain early detection of potential machinery issues, enabling proactive maintenance strategies that improve reliability and reduce operational risk.

System Role and Integration

The 3500/42M is a core vibration monitoring module in the Bently Nevada 3500 rack system. It works with other modules to form a comprehensive machinery protection system.

Typical integration includes:

• Proximitor inputs: For radial and axial vibration measurements
• 3500/15 Power Supply Module: Provides stable rack power
• 3500/32M Temperature Monitor: Monitors bearing and casing temperatures
• 3500/22M Transient Data Interface (TDI): Connects rack data to DCS or historians
• 3500/50 Proximitor Monitor: For additional vibration/position inputs

The 3500/42M continuously processes vibration data, compares readings against user-defined limits, and activates alarms or trips when necessary. It’s fully compatible with other 3500 modules, enabling seamless integration into a facility-wide condition monitoring strategy.
