BENTLY 133819-01
Product Introduction
The Bently Nevada 133819-01 is a rugged industrial velocity transducer designed for permanent machinery monitoring in extreme environments. Part of Bently Nevada’s comprehensive condition monitoring portfolio, this sensor provides reliable velocity-based vibration measurements (100 mV/in/s sensitivity) for predictive maintenance of turbines, compressors, and other critical rotating equipment.
Featuring a hermetically sealed 316 stainless steel housing, the 133819-01 withstands harsh conditions including moisture, chemicals, and explosive atmospheres. Its broad frequency response (4.5 Hz to 10 kHz) captures both low-speed machinery dynamics and high-frequency bearing defects, making it invaluable for comprehensive asset health monitoring.
