Overview

The Bently Nevada 177990-01 Prox Accel Aero (PAA) Module is part of the ADAPT 3701/44 Aeroderivative Monitor system, designed specifically for high-performance monitoring of aeroderivative gas turbines and other fast-rotating machinery. With 12 independent dynamic input channels, it supports precise measurement of vibration, shaft position, and aero-specific dynamic parameters — ensuring early detection of developing faults.

Moreover, its ability to integrate data from multiple sensor types simultaneously allows for enhanced diagnostic depth and improved machinery protection. Built for harsh industrial environments, the module features CE certification and is trusted worldwide in aviation, power generation, and oil & gas facilities.

For example, in a mobile gas turbine package, the 177990-01 can detect bearing degradation or imbalance in real time — reducing unplanned downtime and maximizing equipment life.
