Bently Nevada 330106-05-30-10-02-05

This probe is a key component of the Bently Nevada 3300 XL series vibration monitoring system. The system is widely used in heavy industries such as petrochemicals, power generation, and metallurgy to monitor and protect large rotating machinery (such as turbines, compressors, pumps, and fans).

This probe is a non-contact displacement sensor specifically designed to measure shaft vibration, axial displacement, and shaft position of rotating machinery.

This specific model, as indicated by its numbering, can be interpreted as:

330106: 3300 XL 8 mm reverse-mount probe

05: 50 mm overall housing length

30: 3.0 m threadless segment length (Probe Tip)

10: 1.0 m total probe length

02: Miniature ClickLoc™ coaxial connector

05: Multiple certification bodies, such as CSA, ATEX, and IECEx, indicating it is suitable for hazardous or explosive environments

Main Features

The primary function of this probe is to provide high-precision data for mechanical protection and condition monitoring systems, enabling timely detection of mechanical failures and preventing equipment damage.

Non-Contact Measurement: It utilizes the eddy current effect to precisely measure the distance between the probe tip and the conductive target surface without contacting the measured object (typically the surface of a rotating shaft).

High Accuracy and Reliability: As part of the 3300 XL series, it is renowned for its high measurement accuracy and long-term stability, enabling it to operate reliably in harsh industrial environments.

Monitors Vibration and Displacement: By converting the voltage signal output from the probe into displacement or vibration values, it can monitor the vibration amplitude, shaft center trajectory, and axial position changes of rotating machinery in real time. This is critical for predicting and diagnosing faults such as bearing issues, rotor imbalance, and misalignment.

Certified for Hazardous Environments: With “05” multiple certifications, this probe can be safely used in environments where explosive gases or dust may be present.

Reverse Mount Design: This design allows installation from the inside or back of the machinery under specific space constraints, providing greater installation flexibility.

Robust and Durable: The probe tip is made of polyphenylene sulfide (PPS) material, while the probe housing is constructed from stainless steel, ensuring durability in harsh conditions such as high temperatures, high pressure, and oily environments.
