Product Details:

The BENTLY NEVADA 3500/25 125792-01 enhanced Keyphasor module is a half-height dual-channel plug-in card for the Bently Nevada 3500 TSI machinery protection system. It receives pulse signals from proximity probes or magnetic speed pickups installed on the rotating shaft, converts shaft notch pulses into digital once-per-turn reference signals, and sends the synchronized timing signal to all vibration monitor modules on the rack backplane. This Keyphasor signal is the core reference for shaft rotating speed, vibration phase measurement, orbit diagram, Bode plot and order tracking analysis. The module has two independent isolated input channels, supports -24Vdc transducer excitation for proximity probes. Users can install two 3500/25 modules to build redundant Keyphasor signal configuration for high-reliability TMR turbine projects. Front panel LED indicators display module OK status and input signal fault alarm for daily inspection. This model 125792-01 is the older version of enhanced Keyphasor, and the updated replacement part number is 149369-01. It supports hot swapping during rack operation, replacing the module will not interrupt other monitoring channels. Built-in signal abnormality diagnosis function, can detect probe open circuit, short circuit and missing pulse faults. 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 phase reference for rotating machinery vibration monitoring and fault diagnosis.
