Bently Nevada 128240-01 Key Features
Triple-redundant architecture: The 128240-01 utilizes two-out-of-three voting logic, maintaining overspeed protection even in the event of a single channel failure, with an MTBF exceeding 250,000 hours.
Transient capture capability: 10ms-level response speed accurately captures turbine load rejection events, making the Bently Nevada 128240-01 a recommended solution for API 670 standards.
Backlash adaptive technology: Automatically compensates for signal fluctuations caused by gear eccentricity and wear, ensuring measurement stability of the 128240-01 even under degraded lubrication conditions.
Phase-locked filtering: Suppresses harmonic interference from variable frequency drives, maintaining ±0.05% speed accuracy in VFD-powered equipment.
Application examples of foreign nuclear power plants
Nordic geothermal power plant: 12 ORC turbine units utilize 36 128240-01 modules. Using a two-out-of-three logic, the module successfully intercepted two overspeed events in 2023 (triggering time <8ms).
Kuwait seawater booster pump station: In sandy water environments, the 128240-01's backlash compensation technology reduces the speed false alarm rate to 0.001 per year.
