Product Detail

PN: 3500/40M, Part No: 140734-01
Brand: Bently Nevada (Baker Hughes)
Series: 3500 Machinery Protection TSI System
Type: 4-Channel Proximitor Displacement Monitor Module
Function: Exclusive signal conditioning module matched with 3300XL series eddy current proximity probes, does not support velocity or acceleration sensors unlike 3500/42M. Channels work in paired groups (Ch1+Ch2 / Ch3+Ch4), configurable to monitor shaft radial vibration, thrust bearing axial displacement, rotor differential expansion, shaft eccentricity and REBAM bearing wear parameters. It outputs Alert/Danger two-stage alarm logic and 4-20mA analog signals, uploads real-time data to upper monitoring system to implement interlock protection for rotating equipment

Four independent input channels, strictly paired channel configuration, two measurement tasks per module at most
Fully compliant with API 670 standard, supports TMR triple redundant safety configuration for critical unit protection
Front panel BNC buffered output ports for on-site waveform debugging without system shutdown
Comprehensive self-diagnosis to detect probe open circuit, short circuit and module communication faults
Hot-swappable rack design, front LED indicators for power, running status and channel alarm status
Modbus register mapping configurable via official rack software for data docking with DCS and PLC

Matched Rack: All standard 3500/05 series 12-slot & 14-slot monitoring chassis
Mandatory Matching Rear Card: 135489 series internal termination I/O board
Supporting Sensors: Only Bently 3300XL eddy current proximity probe series
Supporting Software: 3500 rack configuration software, System 1 condition monitoring platform
Not Compatible: Velomitor/accelerometer sensors, external termination rear boards, non-M series monitor modules

Axial thrust displacement and radial vibration safety monitoring for steam turbines, gas turbines and centrifugal compressors in power and petrochemical industries
Rotor differential expansion and shaft eccentricity abnormal early warning and emergency trip interlock
Spare replacement and system reconstruction of legacy 3500 TSI machinery protection racks
