Product Brief: 3500/40 140734-01 + 125680-01
This document provides a concise overview of the integrated system comprising the 3500/40 Vibration Monitor (Part: 140734-01) and its associated front-end interface or accessory module (Part: 125680-01). This system is a core component of the Bently Nevada 3500 Machinery Protection Series, designed for continuous, reliable monitoring of critical rotating machinery in industrial settings.
Primary Application Scenarios:
Industrial Turbines (Steam & Gas): Monitoring shaft vibration, eccentricity, and speed for protection against damage.
Centrifugal & Axial Compressors: Ensuring safe operation by detecting excessive vibration and axial thrust conditions.
Large Pumps & Motors: Protecting high-power driven equipment from bearing failures and mechanical imbalances.
Generators & Gearboxes: Providing essential vibration data for predictive maintenance and fault prevention.
Overall Plant Asset Protection: Serving as a key element in condition monitoring systems to enhance operational safety, prevent unplanned downtime, and enable predictive maintenance strategies.
Key Parameters & Specifications:
| Parameter Category | Specification Details |
|---|---|
| Core Function | 4-Channel Vibration Monitor (Typically for Radial Vibration via Proximitor probes). Provides continuous monitoring, alarm (Alert/Danger) setpoints, buffered sensor outputs, and 4-20 mA transmitter outputs. |
| Part Numbers | Main Monitor: 3500/40 140734-01 Associated Module/Accessory: 125680-01 (Note: Exact function of this specific part should be verified with official documentation. It is commonly a related module like a 3500/15 TMR (Triple Modular Redundant) Backplane or a specific configuration accessory). |
| Key Features | - Four Monitoring Channels - Dual Alarm Setpoints per Channel (Alert & Danger) - Dynamic & Gap Voltage Display (via framework) - OK, Alert, Danger Status Indicators - Buffered Raw Sensor Outputs - 4-20 mA Outputs per Channel (scalable) - Integral Power Supply (from 3500 rack) |
| Physical Dimensions (Typical 3500 Rack Module) | Height: 318 mm (12.5 in) Width: 19 mm (0.75 in) - Single Slot Width in rack Depth: 206 mm (8.1 in) |
| Weight (Approximate) | Module: 0.9 kg (2.0 lbs) Note: System weight depends on full rack configuration. |
| Power Requirements | Powered by the 3500 rack backplane. Typical voltage: +15V DC, -15V DC. |
| Operating Environment | Temperature: 0°C to +65°C (+32°F to +149°F) Humidity: 5% to 95% RH, non-condensing. |
| Compliance & Standards | Designed to meet industrial standards for EMI/RFI immunity and emissions. Typically certified for use in safety systems (SIL2 capable as part of a configured system). |
Important Note: The part number 125680-01 requires precise identification. For absolute accuracy regarding its specific role, dimensions, and integrated system parameters, consulting the official Bently Nevada (a Baker Hughes business) 3500 Series Product Guide or technical datasheets is essential.
