Comprehensive Product Specification, Applications, Advantages, Related Models, and FAQ
The Bently Nevada 330104‑00‑15‑10‑02‑CN is a high‑precision eddy current proximity probe designed for non‑contact measurement of shaft vibration and displacement in rotating machinery. This probe is widely used in industrial condition monitoring systems to provide early warning of machinery degradation, allowing for predictive maintenance rather than reactive repairs.
This model is configured with a 15‑foot cable and a region‑specific connector variant (“CN”) that conforms to specific installation standards. The eddy current sensing technology used in this probe enables it to detect minute changes in the distance between the probe tip and a conductive shaft surface without physical contact. The result is a voltage signal proportional to displacement that is stable, repeatable, and suitable for long‑term monitoring.
The rugged design allows it to function in harsh industrial environments where oil, dust, vibration, and temperature extremes are common. It is a critical component of machinery protection systems that help prevent catastrophic failures in high‑value rotating equipment.
The 3300 XL series is a well‑established family of proximity probes designed for industrial vibration and position monitoring. Probes in this series are known for stable signal output, robust construction, and compatibility with a wide range of machinery protection and condition monitoring modules.
Bently Nevada is a global leader in machinery protection and condition monitoring technology. Its products are used worldwide in critical industrial environments such as power generation, petrochemical processing, and heavy manufacturing. The brand is synonymous with long service life, high reliability, and accurate measurement.

The 330104‑00‑15‑10‑02‑CN proximity probe is used for continuous monitoring of critical rotating machinery in industrial facilities. Common applications include:
Accurate real‑time vibration data enables detection of imbalance, misalignment, rubbing, looseness, and early bearing degradation, supporting predictive maintenance strategies and reducing unplanned downtime.
Non‑Contact Measurement
Eddy current sensing eliminates physical contact with the shaft, preventing wear on both the probe tip and rotating surface, resulting in longer service life and more stable readings.
High Precision and Linearity
The 8 mm probe diameter and optimized coil design provide accurate and linear output over the measurement range, enabling reliable interpretation by monitoring systems.
Rugged Industrial Construction
Stainless steel tip and industrial‑grade armored cable allow the probe to function reliably in environments with oil, dust, vibration, and high temperatures.
Stable Signal Output
Designed to resist electrical noise and maintain consistent performance in electrically challenging environments.
Wide Operating Temperature
Operates effectively from ‑35 °C to +177 °C, supporting installations in diverse industrial settings.
Flexible Installation
The longer 15‑foot cable allows for flexibility in positioning the monitoring electronics relative to the probe and machine, accommodating complex layouts.
