Description
Overview
The Bently Nevada 330704‑000‑060‑90‑02‑CN proximity probe is part of the 3300 XL 11 mm transducer family, engineered for extended‑range non‑contact vibration and displacement measurement on large rotating machinery. Its larger sensing tip provides a significantly wider linear range than 5 mm and 8 mm probes, making it suitable for applications requiring broad measurement capability and high accuracy.
Functional Characteristics
This probe operates within the 3300 XL Proximity Transducer System, delivering a standard sensitivity of 3.94 V/mm (100 mV/mil). The 11 mm design supports long‑range measurements and is commonly used in axial position, differential expansion, rod drop, and zero‑speed detection.
The 330704‑000‑060‑90‑02‑CN is built with an M14 × 1.5 threaded housing and armored cable protection. Its 60 mm minimum case length ensures mechanical rigidity, while the integrated 9.0 m cable with a ClickLoc miniature coaxial connector provides secure, long‑distance signal transmission.
This model is designed as a modern replacement for older 7200‑series 11 mm and 14 mm probes. When upgrading from legacy systems, a complete transducer system replacement is required to ensure compatibility and measurement accuracy.

FAQ
Q: What makes the 11 mm probe different from 8 mm models It offers a longer linear range, making it ideal for large‑shaft or high‑clearance applications.
Q: Can this probe replace older 7200‑series sensors Yes, but the entire transducer system—including extension cable and Proximitor—must be upgraded.
Q: What cable length is included This configuration includes a 9.0 m integrated cable.
Q: Is the probe suitable for TSI systems Yes. It is widely used in turbine supervisory instrumentation.
