Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series)
The 330104‑00‑09‑10‑02‑05 is an industrial-grade proximity probe designed for monitoring the vibration and displacement of rotating machinery. Part of the 3300 XL 8 mm series, this sensor utilizes eddy current technology to provide non-contact, high-precision measurements critical for condition monitoring and machine protection systems.
This probe converts mechanical shaft movement into an accurate analog signal, enabling real-time analysis of rotor dynamics, detection of early faults, and operational safety measures. The “10” in the model specifies a cable configuration suitable for longer installation runs, while the “05” indicates a standard 5 m cable length. It is built to operate reliably under harsh conditions, including high vibration, temperature variation, and exposure to oils or dust.
Its compact, robust design allows installation in tight spaces without compromising measurement performance, making it ideal for mission-critical rotating machinery.
