Multi-Functional Monitoring

The Bently Nevada 3500/72M integrates rod position, rod drop, and hyper-compressor measurements into a single four-channel module. It combines dynamic and static position tracking, enabling simultaneous monitoring of piston rod vibration (critical for machinery protection) and rider band wear (essential for predictive maintenance). This dual functionality reduces the need for redundant hardware .

Enhanced Channel Configurations

With the latest firmware (version 6.0+), the Bently Nevada 3500/72M supports Rod Position Single 2 and Pair 2 channels. These configurations merge rod drop measurements (e.g., average/instantaneous piston position) with rod position parameters like Pk-Pk displacement and crank angle, providing a unified view of compressor health without signal splitting .

Real-Time Alarms and Customization

The module uses 3500 Rack Configuration Software to program user-defined alert and danger setpoints. It triggers alarms based on real-time comparisons between monitored parameters and configured thresholds, enabling rapid response to abnormal conditions like excessive vibration or rod misalignment .

Probe Flexibility and Durability

Compatible with 1–4 inductive proximity probes, the Bently Nevada 3500/72M operates in temperatures from -40°C to +85°C and features an IP67-rated enclosure for dust/water resistance. Its short-circuit-protected transducer outputs (-24 Vdc) ensure stable performance in hazardous areas .
