Bently Nevada 3500/42M (128229‑01)
Product Introduction
The 3500/42M (128229‑01) is a four-channel Proximitor/Seismic Monitor in the 3500 Series, designed to monitor both vibration and shaft position in rotating machinery. Each channel supports a variety of transducers—such as proximity probes, velocity sensors, or accelerometers—and allows comprehensive diagnostics including radial vibration, thrust position, acceleration, and velocity. It’s built for rack-mount integration in machinery protection systems.
