BENTLY 350094M Axis Alignment and Vibration Analysis Module

Description

BENTLY 350094M is a shaft centering and vibration analysis module, which is the core component of BENTLY 3500 monitoring system. This module is designed specifically for industrial turbomachinery and rotating equipment, and can be seamlessly integrated into the 3500 rack (slots 9-14) as a dedicated interface for the system, used for mechanical alignment diagnosis and dynamic vibration analysis. Unlike conventional vibration modules, the 350094M combines centering measurement functionality with advanced signal processing, allowing engineers to associate centering issues with vibration characteristics – a key insight for conducting root cause analysis.

350094M

Its value proposition lies in simplifying complex alignment workflows. The software driven interface of this module provides step-by-step guidance for single plane and multi plane alignment tasks, while real-time graphical displays (such as polar coordinate graphs and trend graphs) eliminate guesswork. This makes it easy for both experienced technicians and beginners to use, and compared to traditional manual methods, the centering time can be reduced by up to 50%. For factory managers, 350094M has improved operational efficiency by reducing downtime during equipment installation or maintenance.

Main features and advantages:
Dual function accuracy
Center measurement: Supports laser and optical sensor technology to measure radial (offset) and axial (angle) deviations with an accuracy of ± 0.001 millimeters per meter.
Vibration analysis: Integrating fast Fourier transform (FFT), time-domain analysis, and order tracking analysis to detect specific frequency issues related to alignment deviation, imbalance, or bearing defects (such as 1X, 2X harmonics).
Real time visualization: Display real-time alignment deviation maps, vibration trajectories, and phase relationships through the human-machine interface (HMI) or remote software of the 3500 system, making it easy to adjust in real-time.
Industrial grade durability
Environmental adaptability: It can operate within a temperature range of -40 ° C to 85 ° C and withstand peak vibrations up to 10 g, suitable for harsh environments such as engine testing units or offshore platforms.
Modular design: compatible with standard 3500 rack, with hot swappable function, allowing maintenance without shutting down the entire system.
Redundant power supply: Dual 18-32 VDC inputs ensure continuous operation during transient power fluctuations, which is crucial for 24/7 industrial processes.
Workflow optimization
Guidance Wizard: Pre programmed alignment programs (such as soft foot calibration and coupling adjustment) simplify complex tasks and reduce human errors.
Data integration: Export alignment reports and vibration data to SCADA systems via Ethernet/IP or Modbus TCP, enabling cross functional teams to access insights in real-time.
Historical tracking: Store alignment and vibration trends to support predictive maintenance strategies and compliance reporting.
Future Security
On site upgradable firmware: Regularly update the firmware through USB or Ethernet, add new sensor protocols (such as Bluetooth laser tools) and analysis functions, and extend the service life of the module.

Application areas:
During the commissioning process of the steam turbine, 350094M uses laser sensors to measure radial and angular offsets in real time, guiding technicians to adjust the coupling with micrometer level accuracy. In the manufacturing industry, this module optimizes the alignment status of high-speed rotating machinery such as extruders and conveyor systems, reduces bearing wear, and extends equipment life by more than 30%.

This module also addresses the challenges of the oil and gas industry, where reciprocating compressors and pumps operate under extreme loads. By analyzing vibration patterns and centering data, 350094M can identify early stress signs caused by centering deviations (such as increased axial vibration or resonance), enabling preventive maintenance before leaks or mechanical failures occur. Its dual focus on neutralizing vibrations makes it an indispensable tool in the industry for safety, efficiency, and compliance with ISO 1940 (balanced mass) standards.

Considerations before installation
Rack setup: Install in a 3500 rack with sufficient ventilation (slot 10 is recommended for dedicated centering tasks) and ensure proper grounding to mitigate electromagnetic interference (EMI).
Sensor calibration: Use BENTLY’s 2080 Plus calibration kit to verify sensor accuracy before installation, especially with laser tools.
Cable shielding: Use twisted pair shielded cables for sensor connections to maintain signal integrity in high noise environments.
Maintenance suggestions
Monthly inspection: Check the health status of the module through the built-in diagnostic functions of the 3500 system, such as voltage level and fan status.
Half year calibration: Use traceable standards to recalibrate laser sensors and vibration channels to ensure measurement reliability.
Firmware management: Schedule quarterly updates to leverage new features (such as enhanced FFT resolution) and security patches.
Data archiving: Regularly backup alignment reports and vibration trends to a centralized server for audit compliance and historical analysis.
