Bently Nevada 330104-10-13-05-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

In the demanding world of industrial machinery, accurate vibration and position monitoring is critical to prevent costly downtime and catastrophic failures. The Bently Nevada 330104-10-13-05-02-CN 3300 XL 8 mm Proximity Probe delivers the precision and reliability needed for continuous protection of rotating equipment. As part of the trusted 3300 XL series, this probe is engineered for harsh environments, featuring an M10 x 1 thread with armor and a miniature coaxial ClickLoc connector for secure signal transmission. Whether used in turbines, compressors, or pumps, this probe provides essential data for predictive maintenance and asset health management.

Technical Specifications Breakdown

The 330104-10-13-05-02-CN probe offers a nominal DC resistance of 7.45 ± 0.50 ohms for the 0.5 meter length, ensuring consistent electrical performance. The probe tip is made of polyphenylene sulfide (PPS), a durable thermoplastic that resists chemicals and wear, while the case is constructed from AISI 303 or 304 stainless steel (SST) for corrosion resistance and structural integrity. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring, making it suitable for pressurized environments. The system operates with a power requirement of -17.5 Vdc to -26 Vdc (or -23 Vdc to -26 Vdc with barriers) at 12 mA maximum consumption, with a sensitivity of less than 2 mV change per volt change in input voltage and an output resistance of 50 ohms.

Industry Applications

This proximity probe excels in monitoring shaft vibration and axial position in critical rotating machinery such as steam turbines, gas turbines, centrifugal compressors, and large pumps. In a typical power generation application, the 330104-10-13-05-02-CN provides real-time gap and vibration data to the protection system, enabling early detection of bearing wear or imbalance. Its robust stainless steel case and PPS tip withstand high temperatures and aggressive media, making it ideal for oil and gas, petrochemical, and heavy industrial environments where reliability is non-negotiable.

Installation & Setup Guidance

Proper installation is key to achieving accurate measurements. The 330104-10-13-05-02-CN probe features an M10 x 1 threaded mounting, which requires careful alignment to ensure the target surface is perpendicular to the probe axis. The unthreaded length is 10 mm, and the overall case length is 13 mm, with a total cable length of 0.5 meters (1.6 feet). When mounting, use the provided armor to protect the cable from mechanical damage. The miniature coaxial ClickLoc connector simplifies connection to the extension cable, but ensure the connector is fully seated and locked to maintain signal integrity. Calibration should be performed against an AISI 4140 steel target as specified by the manufacturer for optimal system accuracy.

Maintenance & Reliability

Routine inspection of the probe tip and cable is recommended to ensure continued performance. Check for physical damage, contamination, or wear on the PPS tip, and verify that the Viton O-ring seal remains intact to prevent pressure leaks. The stainless steel case offers excellent corrosion resistance, but periodic cleaning with a soft cloth and mild solvent (if permitted by site safety guidelines) can remove buildup. The probe's design for differential pressure sealing enhances reliability in high-pressure applications, reducing the risk of false readings. For long-term reliability, follow the manufacturer's guidelines for periodic system verification and calibration checks.

Selection Guide & Purchasing Advice

When selecting the 330104-10-13-05-02-CN, verify that your system requires an 8 mm probe with M10 x 1 thread and the 0.5 meter cable length with miniature coaxial ClickLoc connector. This model includes a country-specific approval option (CN), so confirm compatibility with local regulations. Ensure your Proximitor sensor and extension cable are also 3300 XL 8 mm series components for full system accuracy and interchangeability.
