In‑Depth Product Overview (3300 XL 8 mm Proximity Probe Series)
The 330104‑00‑10‑05‑02‑05 is a precision engineering proximity probe intended for industrial condition monitoring of rotating machinery. It belongs to the 3300 XL 8 mm proximity probe series, a family of non‑contact sensors designed to reliably measure vibration and shaft displacement in a wide range of heavy‑duty applications.
This device uses eddy current technology to sense the distance between its probe tip and a conductive surface, such as a machine shaft. The motion of the shaft causes changes in the electromagnetic field at the probe tip, which are translated into a stable electrical signal. This signal is then used by monitoring systems to analyze machine health, detect early fault conditions, and trigger alarms or protection actions when thresholds are exceeded.
The specific configuration of this model includes a standard 5‑meter cable and industrial connector assembly, identified in the model code as “05” at the end. The “10” section of the model code also indicates an optimized internal calibration and frequency response suitable for typical industrial installations.
Engineered for harsh environments, the 330104‑00‑10‑05‑02‑05 is built to endure mechanical vibration, moisture, dust, and wide temperature ranges without degradation in performance.
