Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series)
The 330104‑00‑11‑10‑01‑00 is a high‑precision 8 mm proximity probe from the 3300 XL Series, engineered for industrial machinery condition monitoring and protection. This probe operates using eddy‑current (non‑contact) technology to measure shaft vibration, displacement, and dynamic movement.
The “11” in the model number signifies an enhanced sensitivity configuration, optimized for precise detection of rotor movement and vibration. The “10” indicates a longer measurement range, allowing more substantial shaft displacement monitoring. The “01‑00” suffix identifies the standard cable and connector interface suitable for integration with industrial monitoring and protection systems.
This probe is specifically designed for critical rotating machinery in industries such as power generation, petrochemical, manufacturing, and heavy processing. It withstands harsh environmental conditions including high vibration, temperature extremes, oil mist, and dust.
