Allen Bradley Rockwell 1440-VST02-01RA B xm-120 Eccentricity Module: Precision Monitoring Solution for Industrial Automation

2025-06-27

1. Product Overview: Key Components for High-Precision Eccentricity Monitoring

• Core Function: Real-time monitoring of the shaft eccentricity of rotating machinery to prevent failures caused by misalignment or bearing wear.
• Applicable industries: Heavy industries such as petrochemicals, electric power, and metallurgical manufacturing.
• Technical highlights: Support dynamic signal analysis, compatible with Allen Bradley's ControlLogix system, and achieve seamless integration.

The module uses a non-contact eddy current sensor with a measurement accuracy of ±1 micron, which can capture tiny shaft displacement changes and provide early warning of potential mechanical failures.

The wide operating temperature range (-40°C to +85°C) is suitable for high temperature and high humidity industrial environments.
Anti-electromagnetic interference design ensures signal transmission stability.

The built-in algorithm can analyze the eccentricity trend and generate a visual report through Rockwell's FactoryTalk software to assist in predictive maintenance (PdM).

In centrifugal compressors and gas turbines, the module can monitor shaft eccentricity in real time to prevent downtime accidents caused by excessive vibration.

Used for bearing health monitoring of steam turbines and hydro-generators to extend the life of key equipment.

In high-speed equipment such as rolling mills and fans, the module helps optimize dynamic balance and improve production efficiency.

• The accuracy of eccentric fault warning increased to 95%, and downtime was reduced by 70%.
• Through data tracing, the bearing installation deviation problem was found and the maintenance process was optimized.

• The sensor needs to be vertically aligned with the shaft surface, and the spacing is calibrated according to the manual (usually 2mm±10%).
• Avoid strong magnetic field interference, and the cable needs to be fixed and protected.

• Perform sensitivity calibration every 6 months.
• Clean the probe surface regularly to prevent oil stains from affecting the signal.

Allen Bradley Rockwell's 1440-VST02-01RA B xm-120 eccentricity module, with its high precision, strong compatibility and intelligent analysis capabilities, has become a core tool for health management of rotating equipment. Under the trend of Industry 4.0 and predictive maintenance, this module not only improves equipment reliability, but also helps enterprises achieve cost reduction and efficiency improvement.
