Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series)
The 330104‑00‑10‑10‑02‑05 is an industrial proximity probe designed for precision measurement of vibration and shaft displacement in rotating machinery. It is part of the 3300 XL 8 mm series, a family of eddy current based sensors widely used for condition monitoring, predictive maintenance, and machine protection.
This probe operates using non‑contact eddy current principles. An electromagnetic field is generated at the probe tip, and changes in the field caused by movement of a conductive surface — such as a shaft — are converted into a voltage signal. This analog signal is interpreted by monitoring systems to determine vibration levels, shaft position and trends over time.
The “10” in the model designation refers to a 10 mm measurement capability range. The “02” indicates the standard industrial connector configuration. The trailing “05” signifies a standard 5 m cable length, which allows flexible positioning between the probe and monitoring hardware. This model is engineered for long‑term dependable operation in harsh industrial environments including high vibration, temperature swings, dust and oil exposure.
