Product Details:

The BENTLY NEVADA 3500/45 140072-04 four-channel position monitor module is a full-height plug-in card for Bently Nevada 3500 TSI machinery protection system. It can be installed in any free slot of the 3500 rack. This module accepts signals from proximity probes, RPT, AC/DC LVDT and rotary potentiometer sensors. It provides -24Vdc excitation for proximity transducers. The four channels are programmed in pairs via 3500 rack configuration software, supporting axial thrust position, differential expansion, case expansion and valve position measurement. Case expansion function can only be used on channels 3 and 4. Engineers can set independent Alert and Danger alarm thresholds for each channel. When the measured value exceeds the preset threshold, the module sends alarm signals to rack relay modules to trigger machinery alarm or shutdown interlock. Each channel outputs 4-20mA analog recorder signal for DCS system connection. 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. This model 140072-04 is a discontinued legacy version. 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 shaft axial position and expansion protection monitoring.
