Bentley Nevada 3500/45 Position Monitor Module. 4-Channel

The Bentley Nevada 3500/45 is a 4‑channel position‑monitoring module used within the 3500 machinery protection rack system. It accepts a wide range of displacement and position transducers and provides continuous machine protection by conditioning input signals and comparing them to user‑configured alarm setpoints. Designed for critical rotating machinery, the module supports sophisticated position‑related measurements essential for predictive maintenance and operational reliability. Made in USA. Technical Specifications: Model: 3500/45 Position Monitor Module Channels: 4 independently monitored channels Compatible sensors: Proximity probes, Rotary Position Transducers (RPTs), DC LVDTs, AC LVDTs, rotary potentiometers Supported functions: Axial/thrust position, differential expansion, ramp differential expansion, complementary differential expansion, case expansion, valve position (channels configured in pairs) Primary purpose: Continuous machinery protection with user-programmable alert and danger setpoints Inputs: Accepts 1–4 signal inputs; input impedance varies by sensor type (DC LVDT 1 MΩ, Proximitor/RPT 10 kΩ, AC LVDT 137 kΩ, potentiometer 200 kΩ) Power consumption: 7.7 W typical (Position I/O), 8.5 W typical (AC LVDT I/O), 5.6 W typical (potentiometer I/O) Sensitivity ranges: Thrust 3.94 or 7.87 mV/μm; Differential Expansion 0.394 or 0.787 mV/μm; Case Expansion 0.05–0.22 V/mm depending on LVDT type Dimensions: approx. 9.50 in × 0.96 in × 9.52 in Weight: approx. 0.91 kg System compatibility: Used in the Bentley Nevada 3500 protection rack; requires matching I/O module mounted at rack rear Application: Turbines, compressors, pumps, generators, motors, and other mission-critical rotating machinery Country of manufacture: USA Please review pictures carefully and let us know if you have any questions!
