Bently Nevada 330105-02-12-50-02-00

Product Overview

The 330105-02-12-50-02-00 extends the Bently Nevada 3300 XL line as a complete 8 mm proximity probe module. This assembly pairs a probe, extension cable, and Proximitor sensor into one tested package. Consequently, engineers gain fast installation and consistent displacement data on turbines and compressors.

Construction and Materials

The probe tip uses polyphenylene sulfide, which resists abrasion and chemical exposure. Meanwhile, the stainless steel housing delivers rugged protection during continuous duty. The Proximitor sensor module adds signal conditioning, so the system outputs a clean voltage directly.

Interface and System Compatibility

This module connects to standard 3300 XL monitors and vibration transmitters. Additionally, its 75 Ω impedance maintains signal fidelity across the entire measurement chain. Therefore, readings stay stable even when plant cabling varies in length.

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.
