Bently Nevada 330104-00-03-05-02-05 8 mm Proximity Probe

The Bently Nevada 330104-00-03-05-02-05 operates as a high-performance eddy current sensor for industrial machinery. This 8 mm probe converts the distance between the tip and target into a proportional voltage signal. Consequently, it tracks both static displacement and high-frequency dynamic vibrations with extreme precision. The system excels at monitoring shaft behavior in fluid-film bearing machines across various sectors. Furthermore, it provides essential data for Keyphasor reference signals and rotational speed calculations.

Advanced Mechanical Construction

This specific model utilizes a 30 mm metric thread with a 0 mm unthreaded length configuration. Bently Nevada incorporates patented TipLoc technology to strengthen the bond between the tip and probe body. Additionally, the CableLoc design ensures the integrated lead can withstand up to 330 N of pull force. The 0.5-meter cable features a miniature coaxial ClickLoc connector for secure, vibration-resistant electrical links. These design improvements significantly extend the service life of the sensor in harsh environments.

System Compatibility and Standards

The 3300 XL series maintains strict adherence to the API 670 standard for machinery protection. This ensures excellent linear range performance and thermal stability during continuous operation. Because Bently Nevada prioritizes modularity, this probe offers full interchangeability with 3300 series extension cables. It also remains backward compatible with non-XL 5 mm and 8 mm transducer systems. Therefore, maintenance teams can upgrade existing installations without performing complex bench calibrations.

Environmental and Safety Compliance

This probe supports safe operation in hazardous locations via its multiple international certifications. The robust housing protects internal components from chemical exposure and high-pressure industrial fluids. While compact and weighing only 0.06 kg, the unit delivers industrial-grade durability for critical asset protection. It represents a reliable solution for preventing mechanical failure in turbines, compressors, and large pumps. The probe serves as a cornerstone for modern predictive maintenance and machinery diagnostic programs.
