Product Description

The 3300/50-01-01-00-00 is a high-performance speed monitoring module in the Bently Nevada 3300 series rack system. It provides continuous, real-time measurement of shaft rotational speed, acceleration, and zero-speed state, serving as a critical safety and monitoring device for high-speed rotating machinery.

Equipped with dual setpoints (Alert and Danger), this module can trigger alarms and trips automatically based on configurable velocity thresholds. A 4-20 mA proportional output ensures seamless integration with PLCs, DCSs, or other supervisory systems, while high-speed processing enables detection of transient speed changes in less than 1 millisecond.

Application Scenarios

  • Steam and gas turbines

  • Large industrial pumps

Ideal for applications requiring:

  • Rapid acceleration monitoring during startup

  • Zero-speed permissive signals for maintenance safety

  • High-speed, hardware-level monitoring independent of PLC scan latency

Functional FAQ

How does this module differ from PLC-based speed counting?
Unlike PLC modules, which can suffer from scan-time latency, the 3300/50-01-01-00-00 operates at a dedicated hardware level with sub-millisecond response, ensuring fast and reliable trip activation during overspeed or rapid acceleration events.

Can the module output data to both local and remote systems?
Yes. It provides a local digital display on the rack front panel and simultaneously sends a continuous 4-20 mA signal to remote DCS or PLC systems for monitoring, logging, and redundancy.
