Introduction
The Bently Nevada 330171-00-20-90-02-05 is a fully configured monitoring module designed for use within the 3500 Series machinery protection system. This specific part number represents a complete assembly typically configured as a four-channel vibration or position monitor, capable of accepting inputs from proximity probes, accelerometers, or velocity transducers. It provides continuous online surveillance of critical rotating machinery, delivering real-time vibration and displacement measurements to detect mechanical faults such as imbalance, misalignment, and bearing wear. The module features independently programmable alarm setpoints, buffered outputs for diagnostics, and supports communication with plant control systems via the 3500 rack interface.
