Bently Nevada 330104-00-08-05-02-CN 3300 XL 8 mm Proximity Probe

Product Introduction

When rotating machinery requires precise vibration and position monitoring, the Bently Nevada 330104-00-08-05-02-CN delivers reliable performance. This 3300 XL 8 mm proximity probe forms part of a proven transducer system designed for non-contact measurement of shaft motion and position. Manufactured in the U.S.A., this probe integrates seamlessly with 3300 XL Proximitor Sensors and extension cables to provide accurate data for predictive maintenance and machine protection.

Technical Specifications Breakdown

The 330104-00-08-05-02-CN features a probe tip made of polyphenylene sulfide (PPS) and a case constructed from AISI 303 or 304 stainless steel (SST). These materials ensure durability in harsh industrial environments. The probe uses an M10 x 1 thread and includes armor for added protection. Key dimensional options include an unthreaded length of 00 mm, an overall case length of 80 mm, and a total length of 0.5 meter (1.6 feet). The connector option is a miniature coaxial ClickLoc connector with standard cable. The nominal probe DC resistance from center conductor to outer conductor is 7.45 ± 0.50 ohms at 0.5 meters. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications

This proximity probe excels in monitoring radial vibration and axial position of shafts in turbines, compressors, pumps, and motors. In a typical steam turbine application, the 330104-00-08-05-02-CN mounts near the bearing to detect shaft displacement, enabling early warning of imbalance or misalignment. Its 8 mm diameter and robust construction suit both new installations and retrofits in power generation, oil and gas, and heavy manufacturing.

Installation Guidance

Proper installation ensures accurate readings. Mount the probe using the M10 x 1 thread into a suitable bracket or housing. Maintain the recommended gap of 1.27 mm (50 mils) to an AISI 4140 steel target for optimal linear range. Use the miniature coaxial ClickLoc connector for secure cable attachment. Ensure the probe tip is clean and free of debris before installation. Follow the manufacturer's guidelines for cable routing to avoid damage.

Maintenance & Reliability

Regular inspection of the probe tip and cable for wear or contamination helps maintain measurement accuracy. The stainless steel case and PPS tip resist corrosion and mechanical stress. The Viton O-ring seal maintains pressure integrity. Verify the probe DC resistance periodically; a reading outside 7.45 ± 0.50 ohms may indicate a fault. For long-term reliability, operate within the specified temperature range and avoid exceeding the probe's pressure rating.

Selection Guide & Purchasing Advice

Before purchasing, confirm that the 330104-00-08-05-02-CN matches your system requirements: 8 mm probe size, M10 x 1 thread, 0.5 meter cable length, and miniature coaxial ClickLoc connector.
