Product Details:

The BENTLY NEVADA 3500/40 four-channel Proximitor monitor module is a full-height plug-in card for the Bently Nevada 3500 TSI machinery protection system. It can be installed in any free slot of the 3500 rack. It receives signals from Bently proximity probes, and supports -24Vdc transducer power supply for eddy current sensors. The module is configured in channel pairs, channels 1&2 as one group, channels 3&4 as another group. Each group can be programmed to measure radial vibration, thrust position, differential expansion, eccentricity or REBAM rolling bearing vibration. Engineers can set Alert and Danger alarm thresholds for each channel via 3500 rack configuration software. When the measured value exceeds the setpoint, the module sends alarm signals to the rack relay modules to trigger machinery alarm or shutdown interlock. Front panel LED indicators display module OK status, bypass state and channel alarm status for on-site inspection. Built-in self-diagnosis function can detect probe open circuit, short circuit and signal abnormality. The module supports hot swapping during normal rack operation, maintenance staff can replace the module without shutting down the whole TSI system. This is the classic legacy version, and the upgraded replacement model is 3500/40M. 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 vibration and axial displacement protection monitoring.
