Description
Overview
The Bently Nevada 330880‑RU‑50‑028‑03‑02 is a PROXPAC XL thermal‑conductivity‑based proximity transducer engineered for precise shaft vibration and position monitoring in heavy‑duty rotating machinery. Designed for long‑term reliability, it provides stable performance in harsh industrial environments where mechanical robustness and corrosion resistance are essential.
Design and Construction
This transmitter incorporates a polyphenylene sulfide (PPS) probe tip, offering excellent chemical resistance and dimensional stability. The unit features a 3/4‑14 NPT mounting thread and is supplied with a complete installation hardware set, including:
These components support flexible mounting configurations across a wide range of machinery housings.
The probe assembly has a maximum length of 5.0 inches, and the retaining nut is designed for secure installation with a torque specification of 29.5 N·m (260 in·lb). Its rugged construction ensures stable mechanical positioning, which is critical for accurate displacement and vibration measurements.
