Description

The Bently Nevada 125972-02 is a 3500/42 Proximitor/Seismic Monitor module designed for the 3500 Machinery Protection System. This four-channel module provides continuous monitoring of vibration and position signals, making it essential for protecting critical rotating machinery such as turbines, compressors, and pumps. It processes inputs from proximity probes, seismic transducers, and velocity sensors, comparing them against user-defined alarm setpoints to trigger alerts or machinery shutdowns as required.

Features

Four independent monitoring channels for flexible sensor configuration.
Supports inputs from Proximitor proximity probes, seismic transducers, and velocity sensors.
Programmable alarm thresholds (Alert and Danger) with configurable voting logic.
Full integration with the Bently Nevada 3500 rack system for centralized diagnostics and data communication.
Software-configurable via the 3500 Rack Configuration Software.

Applications

Shaft vibration monitoring for rotating equipment.
Axial position and thrust monitoring.
Seismic activity detection for industrial machinery.
Critical asset protection in oil, gas, and power generation facilities.
