Bently Nevada 3500/42M 176449‑02 Proximitor / Seismic Monitor Module
The Bently Nevada 3500/42M 176449‑02 is a four‑channel programmable monitor module for the 3500 machinery protection system. It accepts signals from proximity probes and seismic transducers, performs signal conditioning for vibration, thrust position and expansion measurement of rotating equipment.
This module supports configurable alarm thresholds and built‑in sensor fault diagnosis, realizing machinery protection and real‑time status data upload. It is a critical spare component for overhaul and retrofitting of turbine, compressor and large rotating machinery monitoring racks.
