Product Details:

The BENTLY NEVADA 3500/50M two-channel tachometer monitor module is the M-series high-performance speed monitoring card for Bently Nevada 3500 TSI machinery protection system. It can be installed in any free slot of the 3500 rack. The module receives pulse signals from proximity probes or magnetic speed pickups, and calculates shaft rotating speed, rotor acceleration and rotation direction. Two independent channels can be configured via 3500 rack configuration software for overspeed, zero speed, acceleration and reverse rotation alarm logic. It can output conditioned Keyphasor timing signal to rack backplane for other monitor channels, saving an independent Keyphasor module. It has peak hold function to record maximum speed and reverse rotation speed, and the peak value can be manually reset. It cooperates with 3500/22M TDI module to upload steady-state data and high-speed transient waveform data to System 1 fault diagnosis software. Engineers can set independent Alert and Danger alarm thresholds. When the measured value exceeds the preset threshold, the module sends alarm signals to rack relay modules to trigger machinery alarm or shutdown interlock. Front panel LED indicators display module OK status, bypass state and each channel alarm state for on-site inspection. Built-in self-diagnosis function can detect probe open circuit, short circuit and signal loss faults. It supports hot swapping during normal 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, used for rotating machinery overspeed protection and shaft speed monitoring.
