The 3300 XL 8 mm system achieves a standard Scale Factor (ASF) of 7.87 V/mm (200 mV/mil) with a linear range of 2.0 mm (80 mils) when used with AISI 4140 steel targets. This performance meets or exceeds the American Petroleum Institute (API) 670 Standard for linear range, accuracy, and temperature stability. Due to the high precision of the 3300 XL Proximitor sensor and probe manufacturing, the system eliminates the requirement for individual component matching or bench calibration. Furthermore, the 330103 probe incorporates CableLoc design, providing 330 N of pull strength to ensure the physical integrity of the probe-to-cable connection in high-strain industrial environments.
Bently Nevada 330103‑00‑22‑50‑12‑RU is a specific configuration of the 3300 XL 8 mm eddy‑current proximity transducer system, consisting of a probe with M10 × 1 thread, a 5 m extension cable, and approvals for hazardous locations. It is designed for precision shaft displacement and vibration monitoring in industrial machinery.
How reliable is the 3300 XL 8 mm system performance?
The standard 3300 XL 8 mm system fully complies with API 670 mechanical configuration, linear range, accuracy, and temperature stability requirements, ensuring reliable condition monitoring in industrial environments.
Do the components require calibration before installation?
No — the 3300 XL 8 mm proximity transducer components are fully interchangeable and backward compatible with other 3300 series parts, eliminating the need to match or bench‑calibrate individual components prior to installation.
Can 330103‑00‑22‑50‑12‑RU be used in mix with non‑XL components?
Yes — components are backward compatible with non‑XL 3300 series 5 mm and 8 mm parts, but mixed usage will limit the system to the lower performance specifications of the non‑XL components.
What are typical applications of this system?
What are typical applications of 330103‑00‑22‑50‑12‑RU? The system is primarily used for vibration and position measurements on fluid‑film bearing machines, as well as Keyphasor® and speed reference measurements on critical rotating equipment such as turbines, compressors, and generators.
