Product Details:

The BENTLY NEVADA 3500/25-01-01-00 enhanced Keyphasor module is a half-height dual-channel plug-in card for Bently Nevada 3500 TSI machinery protection system. The suffix -01 represents internal termination type, -01 stands for 2 available signal channels, -00 means no special hazardous area certifications, suitable for standard control room environments. This module can be installed in any free slot of the 3500 rack chassis. It receives pulse signals from proximity probes or magnetic speed pickups mounted on the rotating shaft, and converts shaft notch pulse signals into digital once-per-turn Keyphasor reference signals. The phase signal is the basic timing source for shaft rotating speed, vibration phase measurement, orbit plot, Bode diagram and order tracking analysis. It provides -24Vdc transducer excitation for proximity probes. Users can install two 3500/25 modules to build redundant Keyphasor signal configuration for high reliability TMR turbomachinery monitoring projects. Front panel LED indicators display module OK status and signal fault alarm for quick daily inspection. Built-in self-diagnosis function can detect probe open circuit, short circuit and missing pulse faults. This 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.
