The Bently Nevada brand is a globally recognized provider of industrial condition monitoring and machinery protection systems. It offers a wide range of products used to measure vibration, shaft position, and related parameters on critical rotating equipment. Known for robust design, high measurement accuracy, and long‑term reliability, Bently Nevada products are widely used in power generation, petrochemical, oil & gas, heavy industry, and manufacturing facilities.
The model 330104‑00‑08‑05‑02‑CN belongs to the 3300 XL 12 mm Proximity Transducer System Series. This series is designed for eddy current non‑contact measurement of shaft vibration and radial displacement. Probes in this series are compatible with the 3300 XL monitoring platform and are engineered to deliver consistent performance in demanding industrial environments.
The 330104‑00‑08‑05‑02‑CN is a 12 mm eddy current proximity probe used for continuous monitoring of shaft vibration and displacement without physical contact.
This configuration (“02‑CN”) indicates a medium‑length cable paired with a regional connector configuration (CN) suited for localized installation requirements or specific connector standards. The probe transforms the relative radial movement between the probe tip and a conductive rotating surface into an electrical output that can be processed by monitoring hardware.
The robust stainless steel housing and industrial‑grade cable make it suitable for harsh conditions, including vibration, oil contamination, dust, and wide temperature variations. When integrated with the 3300 XL monitoring system, it supports real‑time machinery protection and predictive maintenance.

The 330104‑00‑08‑05‑02‑CN proximity probe is suitable for continuous condition monitoring of rotating machinery where medium cable length and localized connector standards are required. Typical applications include:
This model is particularly well‑suited for installations where the monitoring electronics are positioned a moderate distance from the shaft sensors and where connector standards must fit regional requirements.
Reliable Medium‑Length Cable Configuration
Strikes a balance between flexibility and signal integrity, suitable for moderately distant installations.
Accurate Measurement
Provides stable and repeatable readings enabling early detection of imbalance, misalignment, and other machine faults.
Non‑Contact Operation
Eddy current sensing eliminates wear between the probe tip and the shaft surface.
Rugged Industrial Construction
Resistant to harsh environments, including high temperature, oil, dust, and vibration.
Seamless System Integration
Designed for compatibility with 3300 XL monitoring hardware for complete machine protection.
