Overview

The Bently Nevada 1034549-21 FieldMonitor Seismic Input Monitor is designed for high-integrity vibration and seismic monitoring in critical rotating machinery applications. It supports dual measurement modes by accepting inputs from both proximity probes (relative shaft vibration) and seismic transducers such as accelerometers and velocity sensors (absolute casing vibration).

With built-in self-diagnostics, alarm logic, and compatibility with System 1 platforms, it enhances early fault detection and enables predictive maintenance programs. In power generation and petrochemical operations, the module plays a key role in identifying imbalance, misalignment, bearing failure progression, and structural vibration issues before they escalate into unplanned downtime.

Its compact footprint and CE certification allow global deployment in harsh industrial environments where reliability and safety are essential.
