Product Overview
Product Name
Bently Nevada 3500/22 138607‑01 + 146031‑01
Series
3500 Series – Machinery Protection and Condition Monitoring System
Product Introduction
This product comprises two complementary modules designed for transient data capture within the 3500 Series rack-based monitoring system:
-
138607‑01 – Transient Data Interface (TDI) module. It records rapid, high‑resolution envelope and timewave data from vibration sensors during transient events, such as start‑up, shut‑down, rubs, or shaft impact.
-
146031‑01 – High‑speed Memory Module (HSM) for storing captured transient data. It preserves timelocalized data for post-event analysis and trending to aid in diagnostics.
Together, these modules allow monitoring systems to capture and store detailed vibration events—critical for diagnosing machinery behavior during non-steady-state operations.
Applications
Use cases include:
-
Capturing transient vibration signatures during turbine start‑up and shut‑down phases.
-
Recording impact events like rotor rubs or foreign object intrusions.
-
Collecting timewave data during overspeed or fault conditions.
-
Supporting analysis of bearing or shaft dynamics under transient load changes.
-
Providing diagnostic records for condition‑based maintenance or forensic evaluation.
Industries served:
-
Power plants (nuclear, fossil, combined‑cycle)
-
Oil & gas (compressors, drives)
-
Petrochemicals
-
Heavy manufacturing (motors, gearboxes)
-
Marine propulsion systems
Product Advantages
-
High sample-rate recording captures precise timewave and envelope data.
-
Dedicated storage module ensures critical event data is reliably retained.
-
Hot‑swappable design allows maintenance without interrupting protection.
-
Compact rack form factor preserves space while integrating into standard systems.
-
Detailed diagnostics unlocked by waveform capture improves predictive maintenance.
-
Robust construction enables use in challenging industrial environments.
-
No disruption to real‑time protection logic while capturing transient data.

FAQ
Q1: What does the 138607‑01 module specifically do?
A1: It captures high‑rate transient vibration waveforms when events occur, buffering them for later analysis.
Q2: What is the role of the 146031‑01 module?
A2: It stores the captured transient data securely, allowing retrieval and post‑event review.
Q3: Are these modules safe to swap while operating?
A3: Yes—they support hot‑swap replacement without interrupting the rack’s monitoring or protection functions.
Q4: Where does the stored data go after capture?
A4: The EVENT data remains in the memory module until retrieved by host software or a display module.
Q5: Why is capturing transient data important?
A5: It enables detailed diagnosis of non-steady-state anomalies such as rubs, misalignments, or shock events.
Q6: How much memory does the 146031‑01 module have?
A6: Approximately 8 MB, sufficient for multiple event recordings in a ring‑buffer style.
Q7: What sampling rate does the TDI module support?
A7: Up to around 64,000 samples per second, capturing very high‑frequency detail.
Q8: Are both modules required together?
A8: The TDI module can capture events, but without the memory module, there is nowhere to store them long‑term.
Q9: What kind of machinery is this best suited for?
A9: Any high‑performance rotating asset where transient events carry diagnostic importance—turbines, drive‑trains, compressors.
Q10: Do these modules impact real‑time protection functions?
A10: No. Their operations are designed not to interfere with continuous protection logic—even during data capture.
