Features
Multi-Parameter Integration
3 universal input channels support vibration (proximity/velocity), position, and temperature (RTD) measurements, enabling comprehensive monitoring of rotating machinery health in a single module.
High-Resolution Data Capture
A 51.2 kHz sampling rate per channel ensures detailed signal capture, allowing detection of subtle fault patterns (e.g., early bearing wear) for precise diagnostics.
Flexible Sensor Compatibility
Compatible with a wide range of Bently Nevada and third-party sensors, adapting to diverse machinery types from turbines and compressors to pumps and motors.
Intelligent Alarm Management
User-configurable alarm and danger thresholds with adjustable delays minimize false alarms while ensuring critical faults trigger immediate alerts, supporting timely maintenance actions.
Seamless System Integration
Connects to the 3500 system backplane to share data with the system controller and communication modules, enabling centralized monitoring, remote diagnostics, and integration with SCADA/DCS systems.
Function
The primary function of the 3500/33-01-00 149992-03 is to monitor, process, and analyze multiple critical parameters of rotating machinery. It collects analog signals from vibration, position, and temperature sensors, converts them to digital data via high-speed sampling, and applies advanced filtering to extract key metrics (e.g., vibration amplitude, shaft position, temperature). It compares these metrics against user-defined thresholds, triggering alarms via relays or system alerts when anomalies are detected. By integrating multiple measurements, it provides a holistic view of machinery health, enabling operators to identify interrelated faults and take proactive action.
Use
In industrial settings, the module is installed in the 3500 system rack, connected to sensors mounted on critical rotating equipment such as turbines, compressors, and pumps. It continuously monitors vibration at bearing housings, shaft position, and component temperatures, providing real-time data to operators via local HMIs or centralized control systems. Maintenance teams use its diagnostic data to schedule repairs, optimize maintenance intervals, and prevent catastrophic failures, ensuring reliable operation of high-value industrial assets.
Application Fields
Power Generation
Monitors steam/gas turbines, generators, and feedwater pumps in coal, gas, and nuclear plants, detecting rotor instability, bearing degradation, and overheating to ensure continuous electricity production.
Oil and Gas
Protects centrifugal compressors, pipeline pumps, and gas turbines in upstream, midstream, and downstream operations, withstanding high temperatures and corrosive environments to safeguard energy assets.
Chemical Processing
Tracks vibration, position, and temperature in reactors, mixers, and agitator pumps, enabling early fault detection to prevent leaks, process disruptions, and safety hazards in chemical manufacturing.
Pulp and Paper
Monitors paper machine rollers, motors, and fans, identifying misalignment, bearing wear, or overheating to minimize production downtime and maintain product quality in high-speed manufacturing.
Mining and Metals
Safeguards crushers, conveyor motors, and slurry pumps in mining operations, withstanding dust, vibration, and temperature extremes to ensure reliable performance in rugged environments.
In summary, the Bently Nevada 3500/33-01-00 149992-03 is a versatile multi-function module that enhances the 3500 system’s capability to monitor rotating machinery health.
