990-04-50-02-CN
Bentley 990-04-50-02-CN is a high-precision vibration monitoring module designed for industrial machinery protection systems. Part of Bentley Nevada's 990 series, this component features:
4-channel input for simultaneous vibration/position monitoring.
Dynamic signal processing with wide frequency range (typically 0.5Hz–10kHz).
50mm DIN rail mounting (compatible with standard industrial enclosures).
-CN suffix indicates China-market compliance (CE/GB standards).
Key applications: Turbines, compressors, pumps, and rotating equipment in power generation, oil & gas, and heavy industries.
The module integrates with Bently Nevada 3500/System 1 platforms for real-time condition monitoring and alarm management.
