Specifically engineered for reverse mounting applications, this probe delivers accurate output voltage directly proportional to the distance between the probe tip and the target conductive surface. It enables both static position measurements and dynamic vibration monitoring, making it ideal for automation applications involving fluid-film bearing machines, rotating equipment, and high-speed machinery.

In automation systems, precise measurement of shaft displacement, vibration amplitude, and rotational speed is critical for predictive maintenance and operational efficiency. The 3300 XL 8 mm Reverse Mount Probe integrates seamlessly with Keyphasor® reference systems, providing reliable speed signals and phase data for advanced control systems. Its 5-meter standard system fully meets API 670 standards for mechanical configuration, linearity, accuracy, and thermal stability, ensuring consistent performance even in demanding industrial environments.

The 330105-02-12-05-02-05 probe maintains full interchangeability with other 3300 XL system components, including Proximitor sensors and extension cables. This backward compatibility extends to earlier 5 mm and 8 mm 3300 series probes, simplifying inventory management and reducing the need for individual bench calibration. The probe’s robust design incorporates a patented TipLoc molding technique that strengthens the bond between the probe tip and body, and a CableLoc system providing 330 N (75 lbf) pull strength to secure the cable connection.

For environments where fluid leakage is a concern, the 3300 XL Reverse Mount Probe supports the optional FluidLoc cable system, preventing oil or other liquids from escaping through the probe cable. These features make the 330105-02-12-05-02-05 probe particularly suitable for automated monitoring systems in petrochemical plants, power generation facilities, and heavy industrial machinery, where reliability and precision are essential.

Overall, the 3300 XL 8 mm Reverse Mount Probe represents an advanced solution for automation engineers seeking accurate, reliable, and maintenance-friendly displacement and vibration sensing. Its combination of API compliance, mechanical robustness, backward compatibility, and fluid-tight design ensures long-term operational efficiency in automated industrial environments.
