Bently Nevada 330105-02-12-15-02-05 | 3300 XL Reverse Mount

Product Overview

The 330105-02-12-15-02-05 belongs to the Bently Nevada 3300 XL family of 8 mm reverse mount probes. This sensor measures shaft displacement and vibration without contacting the target. Consequently, engineers favor it for tight installations where standard mounting space remains limited.

Construction and Materials

The probe tip uses polyphenylene sulfide, which resists abrasion and chemical exposure. Meanwhile, the stainless steel body provides rugged mechanical protection during continuous duty. The reverse mount design places the cable exit away from the target, so routing stays clean.

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 remain stable even when cable lengths differ between installations.

Installation Guidelines

A target measuring at least 45 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.
