Bently Nevada 3500 Series

The Bently Nevada 3500 Series is a modular system for continuous machinery protection and condition monitoring of rotating and reciprocating equipment. Its architecture combines a 3500/05 rack, one or two 3500/15 power supplies, a 3500/22M Transient Data Interface, monitoring modules and associated I/O modules. Depending on module selection, it measures shaft and casing vibration, axial position, speed, temperature and differential expansion. Software configuration defines measurement settings and alarm thresholds, while optional relay modules provide programmable voting logic for machinery shutdown circuits. Dual power supplies support redundant operation, and optional Keyphasor modules provide phase references for synchronous vibration measurements. The Transient Data Interface connects to System 1 software for diagnostics, while optional communication gateways transmit measurements and status information to plant control systems.
