Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series)
The 330104‑00‑10‑10‑02‑00 is a high‑precision 8 mm proximity probe designed for condition monitoring and machinery protection of industrial rotating equipment. It belongs to the 3300 XL 8 mm series, which is globally recognized for accuracy, reliability, and durability in harsh industrial environments.
This probe utilizes eddy current technology to measure the radial displacement of a conductive shaft without physical contact. The probe converts shaft motion into a stable electrical signal suitable for integration with monitoring and protection systems. The “10” in the model number indicates a 10 mm measurement range, while the “02‑00” represents the connector type and standard cable length variant, optimized for typical industrial installations.
The probe is constructed with stainless steel housing and tip to resist corrosion, vibration, and mechanical stress. It is suitable for continuous operation in demanding environments, including power generation, petrochemical, and heavy industrial applications.
