The Bently Nevada 330104‑00‑16‑05‑02‑05 is an industrial‑grade eddy current proximity probe engineered for accurate non‑contact measurement of shaft vibration and displacement in rotating machines. It belongs to the widely deployed 3300 XL 8 mm proximity probe family, designed for long‑term duty in challenging industrial environments.
Eddy current technology enables this probe to convert variations in the gap between the sensing tip and a conductive shaft into a proportional voltage output. This output is then interpreted by machine protection and condition monitoring systems to evaluate dynamic behavior, detect early fault conditions, and support predictive maintenance programs.
The specific configuration suffix “02‑05” represents a combination of cable connector type, mechanical fixture option, and cable armor designed for rugged usage. The extended 16‑foot cable increases installation flexibility in large machinery installations where control and monitor racks may be positioned at a distance from the shaft sensor.
The 3300 XL series is recognized for its robust performance, signal stability, and reliability in vibration monitoring and protection systems for rotating equipment. Probes from this series are compatible with standard monitoring modules used in industrial plants worldwide.
Bently Nevada is a trusted brand in the machinery protection and condition monitoring industry. Its sensors, monitors, and protection systems are widely used in power generation, petrochemical, refining, manufacturing, and other heavy industrial sectors where reliable measurement of dynamic behavior is critical.
