一．Bently Nevada 133396-01 Key Features
API 670/612-Compliant Overspeed Protection Logic
The Bently Nevada 133396-01 enables 2-out-of-2 or 2-out-of-3 voting configurations for critical overspeed detection in turbines and compressors. This redundancy meets API 670/612 safety mandates by triggering shutdowns only when multiple modules confirm an overspeed event, minimizing false trips .
Dual-Mode Threshold Sensing with Signal Resilience
Its input stage handles signals from proximity probes or magnetic pickups across +10.0 V to -24.0 V, internally clamping overvoltage transients. Users select:
Auto Threshold: For signals >1 Vpp (min. 0.0167 Hz)
Manual Threshold: Configurable from -23.9 Vdc to +9.9 Vdc (supports low-rpm signals down to 500 mVpp) . Adjustable hysteresis (0.2–2.5 V) prevents relay chatter during speed fluctuations .
