Features

Multi-Channel Monitoring

4 independent channels enable simultaneous vibration monitoring of multiple points on a single machine or across different assets, providing a holistic view of equipment health without requiring multiple modules.

High-Resolution Data Capture

A 51.2 kHz sampling rate per channel ensures detailed capture of vibration signals, allowing detection of subtle fault patterns (e.g., early bearing wear) that lower-resolution monitors might miss.

Flexible Input Compatibility

Supports both proximity probes (for relative vibration) and velocity transducers (for absolute vibration), adapting to diverse machinery types from turbines to pumps.

Intelligent Alarm Management

User-configurable alarm thresholds and delays minimize false alarms while ensuring critical faults trigger immediate alerts, balancing operational safety and productivity.

Seamless System Integration

Connects to the 3500 system backplane to share data with the system controller and other modules, enabling centralized monitoring, remote diagnostics, and integration with SCADA/DCS systems.

Function

The primary function of the 135489-01 is to monitor, process, and analyze vibration data from rotating machinery. It receives analog signals from connected sensors, converts them to digital data via high-speed sampling, and applies advanced filtering to extract key vibration metrics (e.g., peak amplitude, RMS). It compares these metrics against user-defined thresholds, triggering alarms via relays or system alerts when anomalies are detected. By synchronizing with the 3500 system’s Keyphasor module, it enables phase-synchronized analysis, critical for diagnosing rotational faults like unbalance and misalignment. It also stores historical data for trend analysis, supporting predictive maintenance strategies.

Use

In industrial settings, the module is installed in the 3500 system rack, connected to sensors mounted on critical rotating equipment (e.g., turbines, compressors, motors). It continuously monitors vibration at bearing housings, shafts, or casings, providing real-time data to operators via local HMIs or centralized control systems. Maintenance teams use its spectral analysis and waveform data to diagnose faults, schedule repairs, and avoid catastrophic failures. Its analog outputs integrate with PLCs for automated control responses, such as reducing load or shutting down equipment during critical faults.

Application Fields

Power Generation

Monitors vibration in steam/gas turbines, generators, and feedwater pumps, detecting rotor instability or bearing degradation to ensure reliable electricity production and prevent grid-disrupting outages.

Oil and Gas

Protects compressors, pipeline pumps, and gas turbines in upstream drilling, midstream transportation, and downstream refining, ensuring safe and efficient hydrocarbon operations in harsh environments.

Chemical Processing

Monitors agitators, reactor mixers, and centrifuges, enabling early detection of vibration-related faults that could disrupt production or cause hazardous material leaks.

Pulp and Paper

Tracks vibration in paper machine rollers, motors, and fans, identifying misalignment or bearing wear to maintain production efficiency and product quality.

Mining and Metals

Monitors crushers, conveyor motors, and mill drives, withstanding dust and vibration to prevent equipment overload and downtime in rugged mining operations.

In summary, the Bently Nevada 135489-01 is a vital component of the 3500 Machinery Protection System, delivering precise vibration monitoring to safeguard critical rotating machinery. Its advanced features, robust design, and seamless integration make it essential for industries where equipment reliability and operational efficiency are paramount.
