Comprehensive Technical Specification, Application Guide, Advantages, and Recommended Models
The 330104‑00‑14‑10‑02‑05 is a precision eddy current proximity probe engineered for highly accurate, non‑contact measurement of shaft vibration and displacement in rotating machinery. The probe translates variations in distance between its sensing tip and a conductive shaft surface into a voltage signal that monitoring systems can interpret in real‑time. This enables early detection of equipment faults, supports predictive maintenance, and enhances machinery protection.
The model number contains configuration codes that indicate cable length, connector style, and protective features. The “02‑05” suffix denotes a specific armored connector and assembly variation that is designed to withstand demanding industrial conditions while remaining compatible with standard proximity monitoring systems. This model is built for installation in environments with high vibration, contaminants like oil or dust, and temperature extremes.
The 3300 XL series represents a family of high‑reliability proximity probes with robust mechanical construction and stable signal output. Designed for use with industrial condition monitoring systems, these probes are a proven choice for critical rotating equipment across power generation, petrochemical, and manufacturing sectors.
The Bently Nevada brand is globally recognized for producing reliable, high‑performance condition monitoring and machinery protection equipment. Its products are installed in thousands of industrial facilities where long‑term reliability and accurate measurement are essential for safe and efficient operations.
