​Bently Nevada 3300 / 3300 XL Series: 5 mm, 8 mm, and 11 mm Probe System Overview

  • 2025-09-04 09:30:19
Reliable Measurement Support for Mission-Critical Equipment
Customers rely on the Bently Nevada 3300 / 3300 XL Series eddy current displacement probe systems for condition monitoring and asset protection of critical rotating machinery. The series offers three sizes: 5 mm, 8 mm, and 11 mm, tailored to different installation spaces and application scenarios.



System Components and Interchangeability
Each probe system consists of a proximity probe, an extension cable, and a proximitor sensor/transducer, providing a complete measurement chain. It outputs a voltage signal proportional to the probe gap and can simultaneously measure static displacement and dynamic vibration.

The 3300 XL 8 mm system emphasizes modular compatibility: the probe, extension cable, and transducer are all interchangeable, eliminating the need for pairing and recalibration and enabling quick replacement and maintenance. The XL series is also backward compatible with 5 mm and 8 mm components from the earlier 3300 series.



Precision Design and Easy Installation
- Proximitor sensors offer enhanced RFI/EMI immunity and meet EU CE standards without the need for additional shielding or conduit, reducing installation costs.

- The probes and cables feature TipLoc and CableLoc technologies for enhanced structural stability and anti-unplugging, with an optional FluidLoc design for oil leakage resistance.

- The connectors feature a gold-plated ClickLoc quick-lock mechanism, allowing for easy finger engagement and tool-free installation, ensuring fast and reliable installation.



Unique Value and Industry Trust
Bently Nevada has over 50 years of experience in the design and manufacturing of eddy current probes, ensuring industry-leading accuracy and stability.

Compatibility and consistency are key features of the 3300 XL system: the use of standard components supports common factory inventory, reducing maintenance costs and the risk of misuse.



Sample Application Scenarios

- Use the 3300 Series 5 mm probe in compact applications, such as small units and gearboxes with structural constraints.


- For mainstream rotating equipment, the 3300 XL 8 mm probe system is recommended for its high compatibility and interference-resistant installation advantages.


- For large or demanding applications, the 3300 XL 11 mm probe system offers greater mechanical strength and reliability.



Summary

The Bently Nevada 3300 / 3300 XL Series offers a flexible, modular, interference-resistant, and easy-to-install eddy current displacement probe system. Whether meeting the needs of a compact 5 mm installation, standardized 8 mm monitoring, or structurally robust 11 mm applications, this system provides industry-leading measurement reliability and asset protection, helping to improve equipment safety and productivity.
