The Bently Nevada 3500/64M 176449-05 is a Dynamic Pressure Monitor module belonging to the Bently Nevada 3500 Series Machinery Protection System.
The module accepts input signals from dynamic pressure transducers and processes pressure variations to generate measurement values used for equipment monitoring and protection. It continuously compares measured parameters with configured alarm setpoints and can trigger alarms when abnormal conditions occur.
The 3500/64M is mainly used for applications where pressure pulsation and combustion instability monitoring are important, including:
Gas turbine combustion monitoring
Compressor pulsation analysis
Dynamic pressure fluctuation monitoring
Machinery condition protection
Each channel can be configured with measurement parameters and filtering functions through 3500 Rack Configuration Software, allowing engineers to adapt the monitor to different machine operating conditions.

The 3500/64M provides four independent measurement channels, allowing multiple pressure monitoring points to be managed within one protection module.
The module supports configurable frequency filtering, allowing engineers to isolate important pressure signals while reducing unwanted noise interference.
Measured pressure values are continuously compared with configured limits. When abnormal conditions occur, the system can generate alarms to support equipment protection.
The module is designed to work with high-temperature pressure transducers commonly used in demanding industrial machinery environments.
The monitor operates within the Bently Nevada 3500 platform and can work with other protection, communication, and display modules.
