Bently Nevada 176449-03 3500/44M Aeroderivative GT Vibration Monitor

Product Overview

176449-03 is a Bently Nevada 3500/44M Aeroderivative GT Vibration Monitor engineered for continuous vibration monitoring and protection of aeroderivative gas turbines. This four channel monitor operates in critical applications such as power generation, LNG facilities, offshore platforms, and pipeline compressor stations. It continuously compares vibration parameters against configured alarm setpoints and delivers real time machine condition data to operators and maintenance teams. The module supports direct vibration, 1X tracking, and band pass filtering for advanced diagnostics. Its multimode configuration capability allows dynamic alarm profile switching based on turbine operating modes. This functionality helps operators reduce false alarms, improve fault detection accuracy, and prevent unexpected turbine shutdowns.

Technical Configuration

The 3500/44M monitor uses a modular architecture optimized for aeroderivative turbine monitoring:

• Four channel vibration monitoring platform for gas turbine applications

• Supports Velomitor sensors, accelerometers, and interface modules

• Compatible with Aero GT I/O, Prox/Velom I/O, and multimode I/O modules

• Supports signal integration, tracking filters, and configurable band pass filtering

• Accepts dual Keyphasor inputs for independent tracking filter operation

• Provides multimode alarm configuration with up to eight alarm parameter sets

• Includes buffered transducer outputs and recorder outputs for external systems integration

This configuration enables precise turbine vibration analysis under varying operating conditions.
