The 3500/64M 176449-05 is a four-channel dynamic pressure monitoring module designed for continuous machinery protection and process monitoring applications. It accepts input signals from high-temperature pressure transducers and processes dynamic pressure measurements for vibration and pressure pulsation analysis in rotating equipment systems.
The monitor supports configurable bandpass filtering, notch filtering, and recorder outputs for integration with plant control systems. Each channel can generate independently configured measured variables, alert levels, and danger alarms using the 3500 Rack Configuration Software.
The 3500/64M 176449-05 Dynamic Pressure Monitor continuously compares measured values against configured alarm setpoints to support machinery protection functions and provide diagnostic information for operations and maintenance personnel.
The module supports both 2-wire and 3-wire pressure transducers and can operate in Cascade Mode, allowing one transducer input to feed all four monitoring channels with different filter configurations and full-scale ranges.
Typical installations include turbines, compressors, pumps, fans, and other critical rotating machinery requiring dynamic pressure monitoring within Bently Nevada 3500 Series machinery protection systems.
