API 670-Compliant: 3500/22M 138607-01 – BENTLY’s Multi-Sensor Protection Module
Description:
The 3500/22M 138607-01 is a high-density 16-channel monitoring module from BENTLY Nevada(now part of ABB),a global leader in rotating machinery protection.As a flagship component of the BENTLY 3500 Machinery Protection System,it specializes in aggregating and processing data from proximity probes,seismic sensors,and RTDs to track key health metrics—including vibration,shaft position,and temperature.Designed for industrial environments,it transforms raw sensor data into actionable insights,enabling proactive maintenance and preventing unplanned downtime.
Application Scenarios:
A major North American power plant operated 8 gas turbines with outdated 4-channel monitoring modules,which forced technicians to juggle multiple systems to track all critical assets.This fragmented approach led to delayed detection of a bearing vibration spike,resulting in a turbine shutdown that cost$350,000 in lost generation.After upgrading to 3500/22M 138607-01 modules,the plant consolidated monitoring into a single 3500 framework.The 3500/22M 138607-01’s 16 channels covered all turbine bearings,and its real-time alarms detected a subsequent thrust position anomaly 48 hours before failure.Maintenance teams addressed the issue during a scheduled outage,avoiding another costly shutdown.Today,the plant reports 92%fewer unplanned turbine stops—all thanks to the module’s comprehensive monitoring capabilities.

Technical Principles and Innovative Values:
Innovation Point 1:16-Channel Density.Unlike 4 or 8-channel alternatives,the 3500/22M 138607-01 consolidates monitoring for multiple assets(e.g.,a full turbine train)into one module.This reduces rack space usage by 60%and cuts cabling costs by 40%in large-scale systems like refineries or power plants.
Innovation Point 2:Multi-Metric Flexibility.Each channel of the 3500/22M 138607-01 can be independently configured to track different metrics(e.g.,Channel 1 for radial vibration,Channel 2 for temperature).This eliminates the need for specialized modules,making it adaptable to diverse machinery—from centrifugal compressors to hydroelectric generators.
Innovation Point 3:Predictive Alarm Logic.The module uses BENTLY’s proprietary algorithms to differentiate between normal fluctuations and critical anomalies.For example,it flags gradual vibration increases(a sign of bearing wear)vs.sudden spikes(a sign of imbalance),reducing false alarms by 75%compared to generic monitoring tools.
Application Cases and Industry Value:
Case 1:Oil Refinery Compressor Fleet Protection
A European oil refinery struggled to monitor 12 centrifugal compressors with legacy 8-channel modules,leading to overlapping systems and missed alerts.They deployed BENTLY 3500/22M 138607-01 modules to each compressor,using 16 channels to track vibration,thrust,and temperature across all bearings.Within 3 months,the 3500/22M 138607-01 detected a 25%increase in radial vibration in a key compressor—indicating impeller damage.The refinery scheduled repairs during a planned maintenance window,avoiding a catastrophic failure that would have cost$1.2 million in downtime and repairs.Post-upgrade,the refinery’s compressor reliability rose from 85%to 98%.
Case 2:Hydroelectric Plant Generator Monitoring
A South American hydroelectric plant needed to comply with strict regulatory standards for generator safety.They integrated BENTLY 3500/22M 138607-01 modules into their 3500 system to monitor 16 generator bearings.The module’s API 670 compliance ensured regulatory approval,while its 4-20mA outputs fed real-time data to the plant’s DCS.During a high-flow season,the 3500/22M 138607-01 triggered an alarm for abnormal eccentricity,signaling a shaft alignment issue.Technicians corrected the alignment within 24 hours,preventing generator overheating and a potential shutdown.The plant now uses the module’s historical data to predict maintenance needs,cutting annual repair costs by$200,000.
