Product Details:

The BENTLY NEVADA 3500/50 133388-02 full-height 2-channel tachometer overspeed monitor module belongs to Bently Nevada 3500 TSI machinery protection system. This module can be installed in any free slot of the 3500 rack. It receives pulse signals from proximity probes or magnetic speed pickups, and calculates shaft rotating speed, rotor acceleration and rotation direction. It can be configured via 3500 rack configuration software for overspeed alarm, zero speed alarm, acceleration alarm and reverse rotation detection. The module can output conditioned Keyphasor timing signal to rack backplane for other monitoring channels, which can save an independent Keyphasor module. It has peak hold function to record the maximum speed and maximum reverse rotation speed, and the peak value can be manually reset. Engineers can set independent Alert and Danger thresholds. When the speed exceeds the preset value, the module sends alarm signals to rack relay modules to trigger machinery overspeed interlock shutdown. Front panel LED indicators display module OK status, bypass state and 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 it 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 speed monitoring.
