Product Description
Bently Nevada PWB78434-01 & PWA78432-01 for 3500/40M 4-Channel Proximitor Monitor
Core Signal Processing & Power Input PCB Set for Machinery Protection & Vibration/Displacement Monitoring
1. Product Overview
The Bently Nevada PWB78434-01 and PWA78432-01 form a matched PCB set for the 3500/40M 4-Channel Proximitor Monitor, a critical part of the 3500 machinery protection system. PWB78434-01 acts as the core signal processing board, handling 4-channel proximity sensor input, data calculation, and alarm comparison. PWA78432-01 serves as the power input board, providing stable power conversion and distribution to the signal processing circuitry via the 3500 rack backplane. Together, they enable real-time monitoring of shaft displacement, vibration, and position for turbines, compressors, motors, and other rotating machinery in power generation, oil & gas, and heavy manufacturing. Both boards are designed for hot-swappable integration with 3500 racks and support independent channel configuration through 3500 software.
