Bently Nevada 330104-06-14-10-02-05 3300 XL 8 mm Proximity Probe

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330104-06-14-10-02-05 3300 XL 8 mm proximity probe delivers precise, non-contact displacement measurements. This probe is part of the trusted 3300 XL series, designed for continuous monitoring of rotating equipment like turbines, compressors, and pumps. With a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, it withstands harsh industrial environments. The 330104-06-14-10-02-05 is built in the USA and carries CSA, ATEX, and IECEx approvals, ensuring global compliance.

Technical Specifications Breakdown

The 330104-06-14-10-02-05 offers several key parameters that define its performance. The unthreaded length is 60 mm (code 06), and the overall case length is 140 mm (code 14). Total length is 1.0 meter (3.3 feet) per code 10. It uses a miniature coaxial ClickLoc connector with FluidLoc cable (code 02) and standard cable. The probe's DC resistance (RPROBE) from center conductor to outer conductor is 7.59 ± 0.50 Ω at 1.0 meter length. The probe tip material is polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel. It is designed to seal differential pressure between tip and case using a Viton O-ring. For accurate operation, the system requires a -17.5 Vdc to -26 Vdc power supply (with non-incendive circuit) and delivers less than 2 mV change per volt change in input voltage. Output resistance is 50 Ω.

Industry Applications

This proximity probe excels in vibration monitoring for critical rotating machinery. In a steam turbine train, the 330104-06-14-10-02-05 measures shaft radial vibration and axial position, helping operators detect early signs of imbalance or misalignment. In a centrifugal compressor, it provides real-time data to prevent catastrophic failures. The probe's 8 mm diameter and M10 x 1 thread make it suitable for standard mounting in bearing housings. Its armored construction and agency approvals (CSA, ATEX, IECEx) allow use in hazardous areas, such as oil and gas facilities.

Installation & Setup Guidance

Proper installation ensures accurate readings. Mount the probe with the M10 x 1 thread into a compatible mounting block or bracket. Gap the probe at 1.27 mm (50 mils) from the target surface (AISI 4140 steel recommended for calibration). Connect the miniature coaxial ClickLoc connector to the extension cable, ensuring a secure fit. Use the FluidLoc cable to prevent fluid ingress in wet environments. Verify the power supply meets -17.5 Vdc to -26 Vdc requirements. For best performance, calibrate the system with the same target material as the monitored shaft.

Maintenance & Reliability

Regular inspection of the probe tip and cable for damage or contamination extends service life. The Viton O-ring maintains seal integrity under pressure differentials. Since the probe operates in harsh conditions, verify the connector is free from moisture or debris. The 330104-06-14-10-02-05 is designed for long-term reliability, reducing unplanned downtime and maintenance costs. For cost-conscious buyers, this durability translates to lower total cost of ownership.

Selection Guide & Purchasing Advice

Before ordering, confirm that the 330104-06-14-10-02-05 matches your system requirements. Verify the total length (1.0 meter) and connector type (miniature coaxial ClickLoc) fit your installation. Ensure compatibility with a 3300 XL Proximitor Sensor and extension cable. For hazardous area use, check that the CSA, ATEX, and IECEx approvals align with your zone classification. plcmatrix.com offers this probe as a reliable option for new installations or replacements.
