Bently Nevada 3500/46M 176449‑06 Turbine Vibration Monitor Module

The Bently Nevada 3500/46M 176449‑06 is a 4‑channel vibration monitor module designed for the 3500 machinery protection system. It accepts signals from accelerometers and velocity transducers to measure casing vibration, detecting mechanical anomalies on turbines, compressors and other rotating equipment.

This single‑slot board provides high‑speed sampling and built‑in digital filtering for vibration waveform and spectrum analysis. It supports adjustable alarm limits and communicates real‑time vibration data and fault alerts to the rack controller. It is widely stocked as aftermarket spare parts for turbomachinery protection cabinet maintenance and on‑site module replacement.
