Description
Overview
The Bently Nevada 330103‑19‑25‑10‑01‑00 proximity probe is an 8 mm eddy‑current sensor designed for precise non‑contact measurement of shaft vibration and displacement. As part of the 3300 XL transducer family, it provides stable linearity, long‑term durability, and seamless compatibility with XL Proximitor Sensors and extension cables.
Design and Construction
This probe configuration includes an integrated extension cable, simplifying installation and ensuring proper system matching. The sensing tip features molded PPS encapsulation, providing enhanced mechanical protection and resistance to thermal and chemical exposure. The larger probe body and thicker encapsulation improve robustness compared to 5 mm probes, making it suitable for demanding industrial environments.
Each 330103‑19‑25‑10‑01‑00 probe is factory‑calibrated to AISI 4140 steel, ensuring accurate measurements immediately upon installation. Calibration for alternative target materials is available when required for specialized applications.

Functional Description
The 330103‑19‑25‑10‑01‑00 probe provides a voltage output proportional to the distance between the probe tip and a conductive target surface. When paired with a 3300 XL Proximitor Sensor, it delivers high‑resolution vibration and displacement measurements essential for machinery protection systems.
Compared to 5 mm probes, the 8 mm design offers improved mechanical strength and better resistance to physical damage. It is recommended whenever installation space allows, as it provides superior reliability and longer service life.
