Product Description
The Bently Nevada 3500/44M Aeroderivitive GT Vibration Monitor is a four-channel monitoring module specifically designed for aeroderivative gas turbines. It provides continuous condition monitoring of critical rotating machinery by measuring, integrating, and evaluating vibration and Keyphasor® data.
It enables real-time analysis by comparing measured vibration parameters against configurable alert and danger setpoints. The module supports multiple operating modes and offers advanced signal filtering capabilities, including 1X tracking, bandpass filtering, and signal integration. Each channel pair can independently track different Keyphasor® signals, enhancing monitoring flexibility for dual-shaft machines.
This monitor seamlessly interfaces with Bently Nevada Velomitor® sensors and accelerometers via Prox/Velom and Multimode I/O modules, ensuring comprehensive vibration diagnostics for both operations and maintenance personnel.
