Functional Description
The 330101‑00‑12‑20‑12‑CN probe is designed for precise vibration and shaft position measurement in rotating machinery. Its 2‑meter cable provides installation flexibility, allowing the probe to be positioned optimally without compromising signal quality. The FluidLoc cable construction prevents oil migration through the cable interior, making it suitable for lubrication‑rich environments such as turbines and compressors.
The probe maintains the required side‑view clearances and tip‑to‑tip spacing associated with 8 mm probes, ensuring compatibility with standard mounting geometries. Its ClickLoc connector provides a secure, vibration‑resistant electrical interface, reducing the risk of accidental disconnection.
As part of the 3300 XL system, the probe is fully interchangeable with extension cables and Proximitor sensors, eliminating the need for matched components or bench calibration. This simplifies installation, maintenance, and system upgrades.
