Overview

The 3500/44M Aeroderivative GT Vibration Monitor is a four-channel monitoring system designed for Aeroderivative Gas Turbine (GT) applications. The Aero GT and TMR Aero GT I/Os interface with velocity transducers via Bently Nevada™ interface modules 86517 and 86497. The monitor utilizes Prox/Velom I/O to connect to Velomitor® sensors and accelerometers. Users can configure the 3500/44M using the 3500 Rack Configuration Software for the following filter options:

• Signal Integration
• 1X Vibration Tracking
• Band-Pass Vibration
