Applications and Industry Context

In industrial operations, rotating machinery such as turbines, compressors, pumps, and generators is the backbone of production. Unexpected failures can result in costly downtime, equipment damage, and safety risks. The Bently Nevada 3500/65 plays a pivotal role in preventing these issues by providing real-time monitoring of critical machinery parameters.

The 3500/65 is designed for environments where reliable, multi-channel vibration and condition monitoring is essential. It finds application in:

• Power Generation: Steam turbines, gas turbines, and generators rely on the 3500/65 for precise vibration and position monitoring.
• Oil & Gas: Pumps, compressors, and high-speed rotating equipment in upstream, midstream, and downstream operations benefit from continuous protection.
• Petrochemical and Chemical Plants: Critical rotating machinery is monitored to avoid unscheduled downtime and catastrophic failures.
• Heavy Industry: Mills, crushers, and kilns require continuous monitoring to maintain safe and efficient operation.

By providing accurate and timely data, the 3500/65 allows maintenance teams to implement predictive maintenance strategies, reducing unplanned outages and extending equipment life.

System Role and Integration

The 3500/65 is a multi-channel machinery monitor module within the Bently Nevada 3500 rack system, designed for seamless integration with other modules for comprehensive machine protection.

Key integration aspects include:

• Proximity and vibration inputs: Captures radial, axial, and dynamic motion data from rotating equipment.
• 3500/15 Power Supply Module: Ensures stable power for all rack modules.
• 3500/32M Temperature Monitor: Provides bearing and casing temperature protection.
• 3500/22M Transient Data Interface (TDI): Interfaces with DCS, SCADA, or historian systems for plant-wide monitoring.
• 3500/42M or 3500/50 Proximitor Monitor Modules: Additional channels for detailed monitoring.

The 3500/65 can simultaneously monitor multiple inputs, providing a complete picture of machine health. Alarm logic and trip points can be programmed per channel to suit the criticality of each monitored asset.
