Bently Nevada 3500/42‑01‑00 Proximitor Seismic Monitor Module
3500/42‑01‑00 is a 4‑channel Proximitor seismic monitor module for Bently Nevada 3500 machinery protection system. It accepts inputs from proximity probes, velocity and acceleration sensors, measuring shaft vibration, thrust position, eccentricity and seismic parameters for rotating equipment. It provides hardware alarm and protection outputs for critical rotating‑machinery monitoring applications.
This hot‑swappable rack‑mount module supports software‑configurable alarm thresholds per channel. It transmits measurement data and fault diagnostic information to the 3500 system rack and upper‑level monitoring software. Compact modular form fits 3500 series rack slots, widely used for turbines, compressors and large‑scale rotating‑machinery safety‑protection cabinets.
