Product Details:

The BENTLY NEVADA 3500/25-01-03-00 enhanced Keyphasor module is a half-height dual-channel plug-in card for Bently Nevada 3500 TSI machinery protection system. The suffix -01 means single half-height card with 2 channels, -03 represents internal barrier I/O with internal terminations, -00 indicates no special hazardous area agency certifications. This module can be installed in any free slot of the 3500 rack chassis. It receives pulse signals from proximity probes mounted on rotating shafts and converts shaft notch pulses into digital once-per-turn Keyphasor timing reference signals. Built-in internal safety barrier design allows direct connection to sensors located in hazardous areas without an external safety barrier. It provides -24Vdc transducer excitation for proximity probes. The Keyphasor signal is the timing foundation for shaft speed, vibration phase, orbit plot, Bode diagram and order tracking analysis. Users can install two 3500/25 modules to build redundant Keyphasor signal configuration for high-reliability TMR turbomachinery projects. Front panel LED indicators display module OK status and signal fault alarm for convenient daily inspection. Built-in self-diagnosis function can detect probe open circuit, short circuit and missing pulse faults. The module supports hot swapping during rack operation, maintenance staff can replace the module without shutting down the whole TSI system. It complies with API 670 turbomachinery monitoring standard, widely applied in petrochemical, power generation and metallurgy industries, matched with steam turbines, gas turbines and centrifugal compressors, providing stable phase reference signal for rotating machinery vibration monitoring and fault diagnosis.
