Bently Nevada 3701/40 177988-01 Prox Accel Seismic Module

Overview

The Bently Nevada 177988-01 PAS Module integrates with the ADAPT 3701/40 Machinery Dynamics Monitor. It provides six vibration input channels plus one Keyphasor/speed input. This module supports multiple sensor types, including proximity probes, accelerometers, seismic transducers, dynamic pressure sensors, and magnetic pickups. It targets complex rotating machinery such as gearboxes, planetary gear systems, and roller element bearing (REB) machines. The module performs advanced signal conditioning and converts raw sensor signals into actionable vibration and position data. It ensures reliable machinery health monitoring through buffered outputs and clear LED indicators.
