Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series)
The 330104‑00‑09‑15‑01‑00 is a high‑performance proximity probe designed for precision monitoring of rotating machinery. It belongs to the 3300 XL 8 mm series, a family of eddy current sensors widely used in industrial condition monitoring and protection systems.
This probe uses eddy current sensing technology to detect the distance between the probe tip and a conductive surface, typically a shaft. When the target moves, changes in the electromagnetic field around the probe tip are translated into a stable electrical signal representative of shaft vibration or displacement.
The “15” code in the model generally signifies a higher‑grade internal configuration with an extended measurement range or tailored calibration compared to standard variants. The “01” and “00” codes refer to standard industrial connector and assembly designations. The result is a balanced product optimized for accurate measurement, stable signal output, and broad application flexibility.
This model is engineered to operate consistently in harsh industrial environments that include vibration, high temperature, lubricant exposure, and airborne contamination. It provides critical input to monitoring and protection systems to support predictive maintenance, early fault detection, and machinery safety operations.
