Bently Nevada 128329-01 Proximitor Seismic Monitor I/O Module

Quick Overview

The 128329-01 is a high-density Proximitor Seismic Monitor I/O Module engineered for the Bently Nevada 3500 Machinery Protection System. This module acts as the physical bridge between field-mounted proximity sensors and the 3500 monitoring rack. By enabling the simultaneous acquisition of proximity and seismic signals, it provides the stable, high-resolution data necessary for the protection of critical rotating assets like turbines, compressors, and large pumps.
