Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series)
The 330104‑00‑10‑10‑01‑CN is a precision industrial proximity probe designed to measure vibration and displacement of rotating machinery without physical contact. It belongs to the 3300 XL 8 mm series, a widely used family of eddy current sensors built for reliability, stability, and accuracy in condition monitoring and machinery protection systems.
This probe detects dynamic shaft movement by measuring changes in the electromagnetic field between its probe tip and a conductive surface, such as a rotating shaft or journal. The motion causes measurable voltage changes that are transmitted as analog signals to monitoring equipment, enabling real‑time analysis of equipment health, early fault detection, and assessment of machinery performance trends.
The model designation reflects specific configuration attributes. The “10” segment indicates a calibrated performance range tuned for broader displacement monitoring, while the “01‑CN” suffix indicates a connector and wiring configuration suited for controlled industrial installations. The result is a reliable sensor designed for challenging conditions, including vibration, high temperature, contamination, and mechanical stress.
