BENTLY NEVADA 176449-02 3500/42M Proximitor/Seismic Monitor

Product Overview

The Bently Nevada 176449-02 is a 3500/42M Proximitor/Seismic Monitor designed for machinery protection and condition monitoring. This four-channel monitor accepts signals from compatible proximity probes and seismic transducers, processes vibration and shaft-position measurements, and compares monitored values against user-configurable alarm setpoints.

Important Notes

• The correct product designation is Proximitor/Seismic Monitor, rather than a generic interface module.

• This is a monitor card, not a standalone sensor or complete monitoring rack.

• A compatible 3500 rear I/O module and rack installation are required.

• Input type, measurement function, termination hardware, and hazardous-area requirements must be checked against the existing system configuration.

• Verify the complete part number, revision, included hardware, and product condition before ordering.
