The Bently Nevada 3500/25 is a dual-channel speed monitoring module within the 3500 Machinery Protection System, designed to ensure operational safety and reliability for rotating equipment. This module specializes in tracking rotational speed, phase reference, and overspeed detection in turbines, compressors, and generators. It accepts inputs from magnetic pickups (MPUs) or proximity probes, providing real-time RPM data and triggering alarms for critical conditions such as overspeed or underspeed events.

Built to withstand harsh industrial environments, the 3500/25 operates across a temperature range of -40°C to 85°C and complies with API 670 standards for machinery protection. Its rugged design features redundant signal processing and self-diagnostic capabilities, ensuring continuous monitoring of equipment like gas turbines and steam turbines. Integration with the 3500 framework allows seamless data sharing for predictive maintenance strategies.

The 3500/25 module supports adjustable speed ranges (0 to 30,000 RPM) and delivers high accuracy (±0.1% of reading) for precise speed tracking. It provides configurable alarm thresholds, relay outputs, and 4-20 mA analog signals for integration with control systems like DCS or PLCs.

The module is certified for hazardous areas (ATEX/IECEx) and features an IP52-rated enclosure for dust and moisture resistance. Compatibility with Bently Nevada's System 1™ software enables advanced analytics, including trend visualization and event logging. Its hot-swappable design and DIN rail mounting simplify maintenance, while redundant power inputs ensure uninterrupted operation in power plants, oil refineries, and marine applications.

Widely used in energy, oil and gas, and heavy industries, the 3500/25 mitigates risks associated with speed-related failures in critical machinery. By monitoring turbine overspeed or compressor rotor stalling, it prevents catastrophic damage and reduces unplanned downtime.

The module's phase reference output synchronizes vibration analysis, enhancing diagnostics for imbalance or misalignment. Its compatibility with legacy sensors and modern IoT platforms supports digital transformation initiatives, while fail-safe relay logic ensures rapid shutdown during emergencies. Trusted for its precision and durability, the 3500/25 underscores Bently Nevada's legacy in delivering scalable solutions that optimize equipment lifespan, operational efficiency, and compliance with global safety standards.
