Product Overview
The 330851-02-000-050-10-00-05 functions as a 25 mm threaded proximity probe within the Bently Nevada 3300 XL series. This sensor captures non-contact displacement and vibration data from rotating machinery. Consequently, engineers depend on it for radial position, axial thrust, and keyphasor measurements.

Construction and Materials
The probe tip uses polyphenylene sulfide, which resists abrasion and chemical exposure. Meanwhile, the stainless steel body delivers rugged mechanical protection during continuous duty. The M30 x 2 thread simplifies mounting, so technicians achieve secure installation without adapters.
Interface and System Compatibility
This probe pairs with 3300 XL extension cables and Proximitor sensors. Additionally, its 75 Ω impedance maintains signal fidelity across the entire measurement chain. Therefore, readings stay stable even when cable lengths differ between installations.
Installation Guidelines
A target measuring at least 75 mm wide ensures complete linear range coverage. Furthermore, technicians must observe side clearance and cable bend radius limits. Correct gap voltage adjustment directly influences measurement accuracy, so verify it after every mounting change.
