Bently Nevada 3500/25-02-01-CN Technical Specifications, Product Overview, Features, Applications, Advantages, Brand, Series, and Recommended Models
Bently Nevada 3500/25-02-01-CN Product Introduction
The Bently Nevada 3500/25-02-01-CN is an industrial-grade Keyphasor® Module belonging to the 3500 Machinery Protection System. It is designed to provide highly accurate shaft reference signals for continuous machinery monitoring and protection. The module processes pulse signals generated by proximity probes or magnetic pickup sensors installed on rotating shafts, creating a precise timing reference that enables vibration monitoring modules to perform phase analysis, rotational speed calculations, vector measurements, and advanced dynamic diagnostics.
As one of the essential modules within the 3500 rack architecture, the 3500/25-02-01-CN ensures that all compatible monitoring modules operate using the same rotational reference signal. This synchronization significantly improves the accuracy of machinery condition monitoring and allows maintenance personnel to identify mechanical abnormalities before they develop into equipment failures.
The module is designed for uninterrupted operation in demanding industrial environments where equipment reliability is critical. It combines advanced digital signal processing with excellent electromagnetic interference resistance, allowing stable operation in electrically noisy environments commonly found in power plants, refineries, petrochemical facilities, mining operations, and heavy manufacturing industries.
The CN configuration is intended for applications requiring localized product identification while maintaining full compatibility with the standard 3500 platform. It offers the same dependable performance, modular installation, and high-precision signal processing expected from the 3500 Series.
Its compact rack-mounted construction allows easy installation, convenient maintenance, and straightforward replacement without requiring extensive system modifications. The module communicates directly through the rack backplane, eliminating the need for external synchronization hardware and reducing installation complexity.
