Product Introduction: 3500/22M-01-01
The 3500/22M-01-01 is a critical monitoring module from the renowned Bently Nevada 3500 series, specifically a Velocity Input / Seismic Monitor. It is designed to continuously measure and monitor mechanical vibration (in velocity units) of machine structures such as casings, bearings, and supports. This module is essential for predictive maintenance, providing early warning of developing faults in rotating machinery like turbines, pumps, and fans by detecting issues such as imbalance, misalignment, and resonance.
