Core features
High-precision overspeed detection
Through the dedicated overspeed protection function, the equipment’s rotational speed is monitored in real time to prevent catastrophic failures.
Supports multi-point settable overspeed thresholds, flexibly adapting to different working conditions.
Multi-channel design
Provides two independent monitoring channels, supporting redundancy or multi-point monitoring to ensure data reliability.
Each channel operates independently, avoiding the impact of a single point failure on the entire system.
Real-time alarm and protection
Built-in warning (Alert) and danger (Danger) alarm mechanisms ensure the safe operation of the equipment.
Supports alarm relay output, which can trigger protection actions or notify the control system.
Sensor compatibility
Can be used with Bently Nevada’s eddy current probes, magnetic sensors, and optical sensors, adapting to various monitoring scenarios.
Modular and integration
As part of the 3500 series, it can be seamlessly integrated with other modules (such as the 3500/22 communication module).
Supports hot-swappable function, allowing module replacement without downtime, simplifying maintenance procedures.
