Bently Nevada is a globally respected brand in the field of industrial condition monitoring and machinery protection. The brand’s products are widely used in high‑value rotating equipment across power generation, petrochemical, oil & gas, and various heavy industrial sectors. Known for high reliability and robust engineering, Bently Nevada solutions enable accurate monitoring of vibration, shaft displacement, and other key machine health parameters, supporting predictive maintenance and operational safety.
The model 330104‑00‑08‑10‑02‑CN belongs to the 3300 XL 12 mm Proximity Transducer Series. This series uses eddy current technology to deliver non‑contact measurement of shaft vibration and radial displacement. It is compatible with 3300 XL monitoring systems, which are widely deployed for machinery protection and condition monitoring across industries.
The 330104‑00‑08‑10‑02‑CN is a 12 mm diameter eddy current proximity probe designed for accurate, non‑contact monitoring of shaft vibration and radial displacement. The “02‑CN” configuration reflects a medium‑length cable and a regional connector type (CN) commonly used in controlled industrial environments.
This probe converts relative movement between the conductive shaft surface and the sensor tip into an electrical signal that is proportional to the displacement. The robust design—including a stainless steel housing and industrial‑grade cable—ensures long‑term durability in harsh environments with oil, dust, vibration, and temperature variations. It is intended for use as part of a complete proximity transducer system tied into a monitoring rack.
