Functional Description
The 330704‑000‑040‑10‑02‑05 probe operates as part of a three‑component transducer system consisting of the probe, extension cable, and Proximitor sensor. When installed, the probe generates a precise voltage output proportional to the distance between the probe tip and the rotating shaft surface. This enables accurate monitoring of:
The armored cable and ClickLoc connector ensure long‑term reliability in high‑temperature, high‑vibration, or oil‑contaminated environments. The probe’s 11 mm design provides a wider linear range compared to 5 mm or 8 mm probes, making it ideal for large‑shaft or high‑displacement applications.

FAQ
Q: Can this probe be used with older 3300 systems? A: Yes. The 3300 XL series maintains backward compatibility with legacy 3300 extension cables and Proximitor sensors when installed as a matched set.
Q: What is the typical linear range of an 11 mm probe? A: The 11 mm probe typically provides a linear range of approximately 4 mm, depending on the target material and system calibration.
Q: Is the probe suitable for Keyphasor applications? A: Yes. The probe supports phase reference and speed measurement when paired with the appropriate Proximitor module.
