Product Details: Bently Nevada 3500/25-02-01-00 is a half-height two-channel Enhanced Keyphasor Module designed for the Bently Nevada 3500 machinery protection system. This Keyphasor Module receives input signals from proximity probes or magnetic pickups, and converts raw transducer signals into accurate digital once-per-turn pulse signals. The generated Keyphasor pulse acts as a precise speed and phase reference for other monitor modules in the 3500 rack, supporting shaft rotational speed calculation, 1X vibration amplitude and phase measurement, orbit plotting and startup/coast-down analysis for rotating machinery. This variant 3500/25-02-01-00 features specified input termination configuration for stable sensor wiring. It supports flexible channel setup, the two channels can be configured for redundant measurement on one shaft or independent measurement for two separate machines. The module supports an input speed range from 1 to 1,200,000 cpm, meeting monitoring requirements for both low-speed and high-speed rotating equipment. It adopts hot-swappable design, allowing technicians to replace the module without shutting down the whole 3500 rack system. Built-in self-diagnosis function continuously detects sensor open circuit, short circuit and internal module faults, and sends fault alarms to the system. Widely used in power generation, petrochemical and heavy industry sites, this Phase Measurement Module provides critical phase reference data for turbines, centrifugal compressors and generators, helping engineers identify rotor faults and implement predictive maintenance.
