Features
Multi-Channel Monitoring
With 4 independent channels, the module monitors vibration from multiple points on a single machine or across different machines, providing a holistic view of equipment health. This eliminates the need for multiple single-channel modules, reducing system complexity.
Advanced Signal Processing
High-speed sampling (51.2 kHz) and digital filtering enable precise analysis of vibration signals, including time-domain waveforms and frequency spectra. This allows for early detection of subtle fault patterns that may indicate impending machinery failure.
Flexible Alarm Management
Users can configure alarm thresholds, delays, and logic for each channel via software, tailoring the system to specific machinery requirements. Relays trigger alerts or safety actions (e.g., shutdowns) when thresholds are exceeded, ensuring timely intervention.
Seamless System Integration
Through the 3500 system backplane, the module communicates with the system controller (e.g., 3500/70M) and other modules, enabling centralized data management, remote monitoring, and integration with SCADA/DCS systems.
Rugged Industrial Design
The module’s robust construction resists vibration, electromagnetic interference (EMI), and temperature fluctuations, ensuring reliable performance in harsh environments such as oil refineries and power plants.
Function
The primary function of the 3500/22-01-01-05 138607-01 is to process vibration data from connected transducers, analyze it in real time, and generate alarms when abnormal conditions are detected. It converts analog sensor signals into digital data, performs spectral analysis, and compares measurements against predefined thresholds. By continuously monitoring vibration patterns, it provides early warning of machinery degradation, allowing maintenance teams to address issues before they escalate into failures. The module also stores historical data for trend analysis, supporting predictive maintenance strategies.
Use
In industrial settings, the module is installed in the 3500 system rack, where it connects to vibration transducers mounted on rotating machinery (e.g., turbines, pumps, motors). It processes signals from these transducers, displays real-time vibration levels on local HMIs, and transmits data to centralized control systems. Operators use this data to assess machinery condition, schedule maintenance, and ensure safe operation. The module’s alarm outputs can trigger visual/audio alerts or automatically shut down equipment to prevent damage in critical scenarios.
Application Fields
Power Generation
In coal, gas, and nuclear power plants, the module monitors vibration in steam turbines, generators, and feedwater pumps. It detects rotor instability or bearing wear, ensuring reliable electricity production and reducing the risk of costly outages.
Oil and Gas
For upstream drilling rigs, midstream pipelines, and downstream refineries, it monitors compressors, centrifugal pumps, and gas turbines. Its rugged design withstands harsh conditions, including high temperatures and corrosive environments.
Chemical Processing
In chemical plants, the module tracks vibration in mixers, agitators, and reactor pumps. Early fault detection prevents leaks or equipment failures, safeguarding personnel and ensuring regulatory compliance.
Pulp and Paper
Mills use the module to monitor vibration in paper machine rollers, motors, and fans. It identifies misalignment or bearing degradation, minimizing production disruptions and maintaining product quality.
Mining and Metals
In mining operations, it monitors crushers, conveyor motors, and slurry pumps. By detecting vibration anomalies, it reduces downtime in rugged environments where equipment reliability is critical for productivity.
In summary, the Bently Nevada 3500/22-01-01-05 138607-01 is an essential component of machinery protection systems, offering precise vibration monitoring, flexible integration, and rugged reliability.
