109549-01 | Bently Nevada | Photoelectric Probe

The Bently Nevada 109549-01 is a critical replacement module designed for the legacy 3300 NSv Proximitor® Seismic Monitor system. This system is a cornerstone for machinery protection and condition monitoring in industrial environments, tasked with safeguarding high-value assets like turbines, compressors, and pumps. The 109549-01 module itself functions as a dedicated power supply and signal conditioning unit, providing the necessary operating power for the system's external proximity probes (which measure shaft vibration and position) and

velocity seismic sensors (which measure casing vibration). It then processes these raw signals into stable, calibrated outputs for the monitoring system.

This module is essential for ensuring the continuous and reliable operation of the entire monitoring rack. It accepts a universal input power source and generates the precise voltages required by the system's internal electronics and external sensors. Furthermore, it conditions the incoming signals from the transducers, preparing them for accurate interpretation by the system's monitoring modules, which can then trigger alarms if pre-set thresholds are exceeded. The 109549-01 is a key component in predictive maintenance strategies, helping to prevent catastrophic machinery failures by providing early warning of developing issues such as imbalance, misalignment, and bearing wear.

As a replacement part, the 109549-01 is specifically intended for maintaining and servicing existing 3300 NSv installations. Its use ensures that these long-standing, robust monitoring systems continue to operate at their original specifications, preserving the integrity of the machinery protection scheme without requiring a costly and complex full system upgrade. Proper installation and configuration by qualified personnel are required to guarantee system
