Bently Nevada 330101-00-20-20-12-CN Proximity Transducer System – 3300 XL Series
Imagine a critical turbine, compressor, or pump shaft beginning to exhibit abnormal radial vibration — without a reliable proximity transducer system in place, that early warning signal goes undetected. The result: catastrophic bearing failure, unplanned downtime, and production losses that can cost hundreds of thousands of dollars per hour. The Bently Nevada 330101-00-20-20-12-CN Proximity Transducer System exists precisely to prevent this scenario, delivering continuous, non-contact shaft displacement measurement that keeps your rotating machinery running safely and predictably.
Within the renowned Bently Nevada 3300 XL Series — the global benchmark for machinery protection and condition monitoring — the 330101-00-20-20-12-CN represents a precisely engineered configuration: a 20 mm diameter probe with a 2.0 m (200 cm) integral cable, paired for use with the 3300 XL signal conditioning system. This series is deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities on every continent, trusted by reliability engineers who cannot afford false trips or missed faults.
