Function Features

• Displacement-Optimized Signal Conditioning: Enhanced hardware and firmware focus on low-frequency shaft displacement measurement (0.1 Hz–1,000 Hz), delivering ±0.15% accuracy—critical for detecting shaft misalignment, rotor rub, and axial movement in turbines and compressors. This outperforms standard modules in capturing subtle shaft movements that precede catastrophic failures.
• Factory-Integrated 1-Meter PTFE Cable: The pre-terminated PTFE cable with dual-layer shielding ensures noise-free transmission of low-amplitude displacement signals, eliminating signal degradation from on-site wiring. PTFE insulation resists harsh chemicals and high temperatures, while the IP67 connector ensures reliability in wet or dusty environments. Installation time is reduced by 50% compared to field-wired setups.
• Single-Channel Targeted Monitoring: Dedicated single-channel design focuses processing power on critical shaft measurements, avoiding cross-channel interference. Ideal for retrofitting into existing systems where specific assets (e.g., turbine high-pressure rotor) require precise displacement monitoring without full system upgrades.
• Dual Isolated Analog Outputs: Two independent 4–20 mA outputs provide redundant signal transmission to primary DCS and secondary monitoring systems. Galvanic isolation prevents ground loops and ensures data integrity, a key requirement for safety-critical applications like nuclear power plant turbines.
• Dual Status Outputs for Enhanced Alerts: Separate dry contacts for sensor faults and displacement threshold alerts enable granular troubleshooting. The displacement threshold output can be configured via DIP switches to trigger warnings at user-defined levels (e.g., 80% of API 670 limits), supporting proactive maintenance.
• Advanced EMI/RFI Shielding: Dual-layer cable shielding and module-level EMI filtering protect against electromagnetic interference from variable-frequency drives, high-voltage cables, and industrial radios. This ensures stable displacement measurements in electrically noisy environments like steel mills and petrochemical refineries.
• Seamless 3500 System Integration: Slots into Bently’s 3500 chassis, integrating with 3500 display modules, alarm logic solvers, and communication modules (Ethernet/Modbus). This modularity allows scaling from single-point monitoring to full machinery protection systems, leveraging existing 3500 infrastructure.
• Extreme Environment Reliability: -40 °C to +70 °C temperature range and rugged shock/vibration resistance enable operation in arctic oil fields, desert power plants, and high-vibration mining equipment. The module maintains accuracy even in harsh conditions that degrade standard monitoring devices.
• User-Friendly Configuration: Front-panel DIP switches for range selection and measurement parameter switching, paired with LED indicators (power, signal, fault, threshold alert), enable on-site setup without specialized software. Technicians can reconfigure the module in minutes for different machinery types.
• Global Compliance & Hazardous Area Support: UL, CSA, and CE certifications ensure compliance with international standards. Optional ATEX/IECEx certification allows installation in explosive environments (e.g., offshore oil rigs, chemical plant reactors) without additional enclosures.

Application Scenarios

• Nuclear Power (Reactor Coolant Pumps): Installed in nuclear power plants to monitor reactor coolant pump shaft displacement. The displacement-optimized design detects subtle rotor movement that could indicate seal degradation, while dual outputs send data to safety-grade DCS and plant monitoring systems. Cables resist radiation-induced degradation in containment areas.
• Oil & Gas (Centrifugal Compressors): Deployed in offshore oil platforms to monitor compressor shaft displacement. The 1-meter cable connects the module (in control room chassis) to Bently 3300 XL proximity probes on compressor casings. IP67 cable connector resists saltwater spray, and ATEX certification supports Zone 1 hazardous areas.
• Petrochemical (Ethylene Cracker Turbines): Used in ethylene cracker plants to monitor turbine shaft misalignment and axial movement. The enhanced displacement accuracy detects rotor rub at an early stage, preventing costly turbine damage. Dual status outputs trigger maintenance alerts and integrate with plant ESD systems.
• Steel Manufacturing (Rolling Mill Gearboxes): Installed in steel mills to monitor rolling mill gearbox input shaft displacement. The module’s low-frequency response captures gear meshing-induced shaft movement, while the PTFE cable resists heat and oil. Displacement threshold alerts prevent gear tooth failure and unplanned production stops.
• Power Generation (Steam Turbines): Deployed in coal-fired power plants to monitor steam turbine high-pressure rotor displacement. The optimized displacement measurement detects thermal expansion-induced shaft movement, ensuring compliance with API 670 standards. Dual outputs provide redundant data to plant DCS and turbine protection systems.
• Marine (LNG Carrier Propulsion Shafts): Installed in LNG carriers to monitor propulsion shaft displacement. The 1-meter cable fits within the compact engine room layout, while the module’s wide temperature range withstands cryogenic-induced ambient temperature fluctuations. Data integrates with shipboard navigation and control systems.
• Mining (SAG Mill Pinion Shafts): Used in mining SAG mills to monitor pinion shaft displacement, a key indicator of gear alignment. The robust cable and module design withstands dust and vibration, while displacement alerts trigger gear alignment checks before catastrophic failure. Compatible with Bently 3300 XL proximity probes.
• Aerospace (Jet Engine Test Stands): Installed in jet engine test stands to monitor engine shaft displacement during ground testing. The high accuracy ensures compliance with aerospace quality standards, while EMI/RFI shielding prevents interference from test stand instrumentation. The 1-meter cable simplifies integration into test cell setups.
• Chemical Processing (Reactor Agitator Shafts): Deployed in chemical reactors to monitor agitator shaft displacement, which indicates bearing wear or impeller imbalance. The PTFE cable resists corrosive chemicals, and displacement threshold alerts prevent reactor leaks and product contamination.
