Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series – Long Cable Variant)
The 330104‑00‑10‑90‑02‑00 is an industrial-grade eddy current proximity probe designed for precise monitoring of shaft vibration and displacement in critical rotating machinery. It belongs to the 3300 XL 8 mm series, renowned for accuracy, durability, and reliability in harsh operating environments.
This model features a longer cable configuration, indicated by the “90” in the model number, which is commonly a 9.0 m length for flexible installations in large machinery or remote monitoring locations. The “02‑00” suffix identifies the connector type and standard industrial configuration suitable for seamless integration with machinery protection systems.
Constructed with stainless steel materials and engineered for robust performance, the probe provides continuous, non-contact measurement and is designed to withstand industrial conditions including temperature extremes, moisture, oil mist, and vibration.
