3500/61-A01-B01 | Dual Channel Speed Monitor

Bently Nevada Dual Channel Speed Monitor 3500/61-A01-B01

Main Features and Advantages

Precision Speed Monitoring: The Bently Nevada 3500/61-A01-B01 delivers highly accurate rotational speed measurement (±0.1% accuracy) using advanced signal processing algorithms. Its dual-channel design allows simultaneous monitoring of two independent shafts or redundant measurement of critical equipment, ensuring reliable overspeed protection even in signal dropout scenarios.

Advanced Diagnostics: Continuous self-monitoring features detect sensor failures, signal degradation, and module faults before they impact operations. Programmable alarm delays prevent nuisance tripping during transient conditions while maintaining critical protection during genuine overspeed events.
