The Bently Nevada 330104-00-04-10-01-05 Proximity Probe Module is a rugged, non-contact eddy-current sensor designed for accurate measurement of shaft vibration, displacement, and position in critical rotating machinery. As part of the proven 3300 XL 8 mm proximity transducer system, this model is engineered for long-term stability, high measurement accuracy, and dependable operation in demanding industrial environments such as power plants, oil & gas facilities, and petrochemical processing units.
This configuration features a 40 mm probe case length (code 04), a 1.0-meter total system length (code 10), and a hazardous-area approved design (code 05), making it suitable for installations where both safety certification and installation flexibility are required. The robust stainless-steel construction and eddy-current sensing principle ensure consistent performance even under high vibration, temperature fluctuations, and contaminated conditions.
By continuously monitoring shaft movement without physical contact, the probe helps maintenance teams detect early signs of mechanical issues such as misalignment, imbalance, and bearing degradation—supporting predictive maintenance strategies and improving asset uptime.
