Description

The 3500/64M Dynamic Pressure Monitor is a high-performance four-channel monitoring module engineered for continuous dynamic pressure measurement in critical rotating machinery applications. Designed to work with high-temperature pressure transducers, 3500/64M delivers accurate bandpass dynamic pressure analysis while supporting advanced machinery protection strategies. Within the Bently Nevada 3500 Series, including modules such as 3500/20, 3500/32, and 3500/60, it provides reliable real-time monitoring for demanding industrial environments.

Using configurable signal processing, the 3500/64M enables users to customize bandpass filter settings, notch filtering, and alarm thresholds through 3500 Rack Configuration Software. The module converts pressure signals into actionable diagnostic information, helping operators detect abnormal process conditions before they escalate into equipment failures.

For turbines, compressors, pumps, and process machinery, the 3500/64M supplies continuous condition monitoring, alarm management, and recorder outputs for integration with plant control systems. Its flexible filtering architecture and multi-channel capability make it an essential component in modern predictive maintenance and machinery protection programs.
