Bently Nevada 330703-000-178-10-02-00 3300 XL 11 mm Proximity Probes

Overview

The Bently Nevada 330703-000-178-10-02-00 proximity probe delivers precise vibration and displacement measurements for fluid‑film bearing machinery. The 11 mm sensing design provides a longer linear range than standard 8 mm probes, supporting demanding industrial applications. The probe integrates with the 3300 XL Proximity Transducer System and supports TSI‑based protection platforms.

Structural Design

The 330703-000-178-10-02-00 includes an 11 mm probe, extension cable, and Proximitor Sensor, forming a complete transducer system. The probe outputs 3.94 V/mm (100 mV/mil), ensuring high‑accuracy displacement measurement. The larger tip diameter increases linear range, making the probe suitable for axial thrust, differential expansion, and rod position monitoring.

The design supports tachometer, zero‑speed, and phase reference measurements using Keyphasor technology. The miniature coaxial ClickLoc connector locks securely with finger‑tight torque and simplifies installation. The probe’s rugged construction maintains stable performance in dynamic, high‑vibration environments.
