Description
Overview
The Bently Nevada 330104‑12‑20‑10‑02‑00 proximity transducer is part of the 3300 XL 8 mm series, designed for high‑accuracy non‑contact measurement of shaft vibration and displacement in critical rotating machinery. Its armored construction and extended mechanical dimensions make it suitable for installations exposed to harsh operating conditions, mechanical stress, and elevated temperatures.
Mechanical Design
This model incorporates an M10×1 threaded body with a 120 mm unthreaded section and a 200 mm armored case length. The probe housing is manufactured from AISI 303/304 stainless steel, providing corrosion resistance and long‑term durability. A Viton O‑ring is integrated into the design to maintain pressure integrity between the probe tip and the case, supporting reliable operation in environments where differential pressure is present.
The probe tip is constructed from Polyphenylene Sulfide (PPS), a material selected for its mechanical strength and thermal stability. This ensures consistent measurement performance across the probe’s operating temperature range of −35°C to +85°C, with storage capability extending from −51°C to +100°C.
Electrical Characteristics
The 330104‑12‑20‑10‑02‑00 includes a 1.0‑meter cable terminated with a miniature coaxial ClickLoc connector. The connector design prevents accidental loosening and maintains shielding integrity, ensuring stable signal transmission to the associated Proximitor sensor.
This probe is fully compatible with the 3300 XL transducer system and supports both static and dynamic measurements, including shaft position, radial vibration, and phase reference signals.
