Description
Overview
The Bently Nevada 330104‑00‑05‑20‑02‑05 proximity probe is an 8 mm eddy‑current sensor engineered for precise shaft vibration and displacement measurement in rotating machinery. As part of the 3300 XL series, it delivers stable linearity, long‑term reliability, and robust mechanical performance in harsh industrial environments.
Design and Construction
This probe uses an M10 × 1 threaded housing with armored cable protection, providing strong resistance to mechanical impact and installation stress. The sensing coil is encapsulated in molded PPS material, offering improved durability and thermal stability. A minimum case length of 50 mm ensures structural rigidity while maintaining compatibility with standard mounting configurations.
The probe includes a 2.0 m (6.6 ft) integral cable terminated with a ClickLoc miniature coaxial connector, enabling secure and repeatable electrical connections. It is approved for use in hazardous areas under CSA, ATEX, and IECEx certifications.

Functional Description
The 330104‑00‑05‑20‑02‑05 probe is designed for applications requiring accurate static and dynamic shaft measurements. Its 8 mm tip provides a balanced linear range suitable for medium‑clearance machinery. The armored cable and reinforced coil encapsulation enhance survivability in environments exposed to vibration, heat, or mechanical interference.
This model is supplied with silicone tape for connector sealing. While suitable for general industrial use, silicone tape is not recommended for installations exposed to turbine oil, where connector protectors are preferred.
Applications
-
Turbine supervisory instrumentation
-
Compressors and expanders
-
Pumps, motors, and gearboxes
-
High‑temperature or vibration‑intensive machinery
-
Hazardous‑area monitoring installations
