Bently Nevada Launches 3500/45 (176449-04): Enhanced Proximitor Power Supply for Machinery Monitoring Systems
Bently Nevada, a Baker Hughes business and global leader in asset condition monitoring, has announced the release of an enhanced version of its 3500/45 Proximitor Power Supply, identified by the part number 176449-04. This critical module serves as the central power source and signal conditioner for eddy-current proximity probe systems, providing reliable, high-fidelity vibration and position data essential for protecting rotating machinery such as turbines, compressors, and pumps.
The 3500/45 module is a core component of the Bently Nevada 3500 rack-based monitoring system. It supplies the precise DC power required to energize proximity probes (transducers) and conditions the returned gap voltage signals. The specific «-04» suffix indicates the latest hardware revision, incorporating component upgrades for improved thermal performance, signal stability, and long-term reliability in the demanding 24/7 environments of power generation, oil & gas, and industrial facilities.
«The integrity of every vibration and position measurement hinges on the quality of power and conditioning provided to the probe,» said a product manager at Bently Nevada. «The enhanced 3500/45-04 module is engineered to be the most reliable foundation for our proximity measurement channels. Its upgrades ensure consistent, clean power delivery, which translates to more stable and accurate machinery health data for our customers.»
Key Features and Benefits of the 3500/45 (176449-04) include:
-
Dual Redundant Power Supply Inputs: Accepts two independent -24 VDC power sources, automatically switching to the backup in case of a primary power loss, ensuring uninterrupted monitoring and protection.
-
High-Density Channel Support: A single module can typically power and condition multiple proximity probe channels (often 8 or 16), optimizing rack space and simplifying system architecture.
-
Enhanced Signal Conditioning and Filtering: Provides stable, regulated probe power and includes advanced filtering to minimize electrical noise on the return signals, resulting in cleaner, more accurate vibration and position data for the monitoring modules.
-
Comprehensive Diagnostics: Features built-in diagnostics to monitor the health of the power supply itself, the connected probes, and cabling, providing early warnings of issues like open or shorted probes.
-
Seamless 3500 System Integration: Plugs directly into the 3500 rack and communicates with the system’s framework module. It is fully supported by Bently Nevada’s System 1® and other diagnostic software for configuration and health monitoring.
The Bently Nevada 3500/45 Proximitor Power Supply (176449-04) is available now as a component for new 3500 monitoring system builds and as a direct replacement/upgrade for existing modules in the field. It is an indispensable component for reliability engineers focused on maintaining the highest data quality for their critical machinery protection and condition monitoring programs.
