Bently Nevada 3500/25-01-01-00 Enhanced Keyphasor Module Overview
Product Description
The Bently Nevada 3500/25-01-01-00 Enhanced Keyphasor Module is part of the Bently Nevada 3500 Machinery Protection System, designed to provide Keyphasor signals to monitor modules in the system rack. It is a half-height, two-channel module that accepts input from proximity probes or magnetic pickups, converting these signals into digital Keyphasor signals. These signals mark the rotation of shafts or gears, enabling precise timing measurements. The module can handle up to four Keyphasor signals in normal configuration and up to eight in a paired configuration.
The Keyphasor module is used for monitoring rotating shafts, measuring rotational speed, vibration amplitude, and phase. The 3500 system’s key function is to track rotational speed and vector parameters, including vibration amplitude and phase. The Enhanced Keyphasor Module builds upon its predecessor by offering expanded signal processing capabilities, while maintaining compatibility with existing legacy systems.
