Product Introduction & Positioning
The 3500/44M 176449-03 is a four-channel aeroderivative gas turbine vibration monitor module within Bently Nevada’s 3500 Series. It accepts inputs from various sensor types including Bently Nevada’s Proximitor and accelerometer sensors via interface modules, enabling detailed vibration analysis. Programmable with the 3500 Rack Configuration Software, the module supports signal integration, 1X vibration tracking, and band-pass vibration filtering to tailor measurements to specific turbine operating modes. It continuously compares vibration parameters against user-set alarm thresholds, providing immediate alerting capabilities critical for fast operational decision-making. Designed for easy integration into 3500 system racks, the module communicates essential machine condition data to operators and maintenance personnel for ongoing asset health management.
Key Technical Features & Functional Benefits
The 3500/44M 176449-03 accommodates four independent vibration channels with a wide frequency response from 1 Hz up to 30 kHz, covering both low-frequency structural and high-frequency bearing and blade pass vibrations. Signal conditioning includes configurable bandpass filters and tracking filters designed specifically for aeroderivative turbines running at speeds from 2,400 to 30,000 RPM. This provides accurate and relevant vibration information aligned with turbine dynamics.
The module’s input impedance for Aero GT I/O exceeds 95 kΩ, ensuring high signal sensitivity coupled with low noise interference. Power consumption is efficient at approximately 7.7 watts, making it suitable for continuous monitoring applications. Temperature tolerance ranges from -30°C to +65°C, accommodating the variable environments typical in turbine enclosures. Integrated alarms can be configured with multiple alert and danger setpoints and timed delays, supporting comprehensive vibration surveillance.
The compact form factor (241.3 mm x 24.4 mm x 241.8 mm) and industrial-grade build facilitate mounting in standard 3500 racks. Communication interfaces allow seamless integration with plant-level monitoring software, supporting predictive maintenance strategies and asset lifecycle planning.
