1. Product Overview and Key Features
The Bently Nevada 3500/15 is a versatile accelerometer monitor module within the 3500 Machinery Protection System, designed for continuous vibration monitoring in critical industrial equipment. This module processes signals from accelerometers to detect machinery faults such as imbalance, misalignment, and bearing degradation. It supports two independent channels, each capable of accepting dynamic acceleration, velocity, or displacement inputs, with configurable frequency ranges (e.g., 10 Hz to 1 kHz or 1 kHz to 10 kHz). The 3500/15 provides 4-20 mA outputs and relay alarms for seamless integration with control systems. Its rugged construction ensures reliable performance in harsh environments (-40°C to 85°C) and complies with API 670 standards. The module’s self-diagnostics and front-panel LED indicators simplify troubleshooting, making it ideal for turbines, pumps, and fans.
2. Technical Specifications and System Integration
Engineered for precision, the 3500/15 offers adjustable bandpass filtering and alarm setpoints to align with ISO 10816 vibration severity guidelines. It accepts input sensitivities up to 500 mV/g and delivers 24 VDC loop power to sensors, reducing external wiring complexity. The module integrates with the 3500 framework, enabling real-time data sharing with Bently Nevada’s System 1™ software for predictive maintenance analytics. Compliant with ATEX/IECEx for hazardous areas and IP52 enclosure ratings, it ensures safe operation in oil refineries, power plants, and chemical facilities. Hot-swappable design and DIN rail mounting allow quick maintenance and scalability, while redundant power options enhance system reliability.
3. Applications and Operational Benefits
The 3500/15 is critical for industries prioritizing machinery health, such as energy, manufacturing, and maritime. By monitoring vibration trends, it enables early detection of mechanical issues, preventing unplanned downtime and costly repairs. Its compatibility with third-party sensors and legacy systems streamlines upgrades, while modular architecture supports expanding monitoring needs. The module’s fail-safe alarms and event capture features ensure rapid response to abnormal conditions, safeguarding equipment like compressors, generators, and gearboxes. Trusted globally, the 3500/15 exemplifies Bently Nevada’s commitment to delivering robust, scalable solutions that enhance operational safety, efficiency, and compliance with industrial regulations.
