Technical Description
The 330104-12-20-10-02-00 is an 8 mm proximity probe from Bently Nevada’s 3300 XL series, designed for high-precision, non-contact measurement of radial shaft vibration and axial displacement in high-speed rotating machinery. Utilizing the eddy current principle, the probe generates a linear voltage signal proportional to the gap between the probe tip and the target shaft. This model features a polyphenylene sulfide (PPS) tip and a corrosion-resistant AISI 303/304 stainless steel case, ensuring robust performance even in aggressive industrial environments exposed to lubricants, steam, and high pressures.

Operational Application
The 330104-12-20-10-02-00 proximity probe is widely used in industries such as power generation, oil and gas, and petrochemical processing to monitor the health of critical rotating machinery like steam turbines, centrifugal compressors, and large electric motors. By monitoring shaft centerline position and vibration vectors, this probe provides real-time data that enables maintenance teams to identify potential issues such as misalignment, bearing degradation, or shaft bow before they lead to costly shutdowns or catastrophic failures.
Frequently Asked Questions
Why is the unthreaded length (120 mm) a critical factor for this model?
The 120 mm unthreaded length is necessary for installations where the probe must pass through non-threaded sections of a machine casing before engaging the installation threads. This ensures the probe tip is correctly aligned with the shaft.
Can this probe be calibrated with non-3300 XL Proximitor sensors?
No, the 3300 XL probe must be used with a 3300 XL Proximitor sensor as part of a matched system. Using this probe with older series electronics will result in non-linear output and inaccurate data due to differences in oscillator frequency and signal processing.
What are the benefits of the ClickLoc connector design?
The ClickLoc connector provides a vibration-resistant, secure connection for the miniature coaxial interface, ensuring that the signal remains stable and protected from moisture, oil, and other contaminants often found in industrial field environments.
