製品紹介
The Bently Nevada 3500/64 Dynamic Pressure Module (part number 176449-05) is an advanced signal processing module designed to monitor dynamic pressure signals in rotating machinery applications. Installed in the trusted 3500 machinery protection platform, this module provides continuous, high-resolution analysis / pressure fluctuations that may indicate combustion instability, surge, pulsation, or other operational anomalies. It is optimized for use with dynamic pressure transducers and is ideal for machinery such as gas turbines and reciprocating compressors where pressure behavior plays a critical role in performance and safety.
As part / Bently Nevada’s comprehensive vibration and condition monitoring ecosystem, the 3500/64 expands traditional monitoring to include a powerful tool for capturing pressure phenomena that would otherwise go unnoticed, enabling predictive diagnostics and process optimization.
