Real-World Use & Application Scenarios
The Bently Nevada 3500/64M 176449-05 Dynamic Pressure Monitor plays a critical role in monitoring high-temperature pressure transducers, primarily in heavy industrial applications such as reciprocating compressors in oil and gas, petrochemicals, and power generation industries. This monitor focuses on providing continuous, real-time measurement of dynamic pressure signals, which are essential for detecting abnormal conditions like valve events, cylinder pressures, and other mechanical performance parameters. By accurately tracking dynamic pressure, the module supports early fault detection, enhances process safety, and minimizes costly downtime. It is especially useful in applications requiring detailed pressure signal analysis to ensure safe and reliable compressor operation.
Product Introduction & Positioning
The 3500/64M 176449-05 is a single-slot, four-channel pressure monitor module within the Bently Nevada 3500 Series machinery protection system. It accepts input signals from high-temperature pressure transducers and uses bandpass filtering to condition these signals, focusing on dynamic pressure as the primary measured variable. Configurable via the 3500 Rack Configuration Software, users can adjust bandpass corner frequencies and apply notch filters to optimize signal quality for specific machinery. The module provides alarm outputs based on user-defined setpoints, driving safety and maintenance actions. It integrates seamlessly with other 3500 system components to form a comprehensive machinery health monitoring solution, offering plant operators critical insights into hydraulic and pneumatic system states.

Key Technical Features & Functional Benefits
The 3500/64M 176449-05 processes dynamic pressure signals with selectable bandpass filter frequencies, including option ranges such as 5 Hz to 4 kHz (low mode) and 10 Hz to 14.75 kHz (high mode), providing flexibility to suit different measurement requirements. The monitor effectively isolates and amplifies weak pressure signals from high-temperature environments, ensuring accurate, noise-free readings.
Each channel supports configurable alert and danger alarm setpoints with programmable time delays to reduce nuisance trips and optimize response timing. Signal conditioning outputs include a recorder output suitable for integration with external control systems for continuous trending and diagnostics.
Designed for rugged industrial conditions, the module operates within a wide temperature range (-30°C to +65°C) and tolerates humid environments (up to 95% non-condensing). It fits a standard 3500 rack slot, offering efficient use of panel space and simplified wiring management.
