Bently Nevada 330104-00-16-05-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

When machinery vibration threatens production uptime, the Bently Nevada 330104-00-16-05-02-CN delivers precise measurement. This 3300 XL 8 mm proximity probe forms the sensing element of a non-contact transducer system, converting shaft displacement into a proportional DC voltage. Designed for harsh industrial environments, it features a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case for durability. The M10 x 1 thread with armor provides robust mounting, while the miniature coaxial ClickLoc connector ensures secure signal transmission.

Technical Specifications Breakdown

The 330104-00-16-05-02-CN operates with a nominal probe DC resistance of 7.45 ± 0.50 Ω from center conductor to outer conductor at 0.5 meter length. This low resistance ensures minimal signal loss over the cable run. The probe tip material, polyphenylene sulfide (PPS), offers excellent chemical resistance and electrical insulation. The case material, AISI 303 or 304 stainless steel (SST), provides corrosion resistance in demanding environments. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring, maintaining integrity under varying process conditions.

Industry Applications

In rotating machinery such as turbines, compressors, and pumps, the 330104-00-16-05-02-CN monitors radial vibration and axial position. Its 0.5 meter (1.6 feet) total length suits installations where the probe mounts close to the target. The miniature coaxial ClickLoc connector simplifies field replacement without special tools, reducing downtime. Compared to older 5 mm probes, the 8 mm design offers improved linear range and sensitivity for critical machinery protection systems.

Installation & Setup Guidance

Mount the 330104-00-16-05-02-CN using the M10 x 1 threaded hole, ensuring the probe tip faces the target surface. Gap the probe at 1.27 mm (50 mils) for optimal performance with an AISI 4140 steel target. Connect the miniature coaxial ClickLoc connector to a compatible 3300 XL extension cable and Proximitor sensor. Verify that the system uses only 3300 XL 8 mm components to maintain accuracy and interchangeability specifications. The probe must be installed per the manufacturer's guidelines to ensure proper sealing and pressure rating.

Maintenance & Reliability

Inspect the probe tip and cable periodically for physical damage or contamination. The PPS tip resists wear, but verify the gap setting during routine maintenance. The stainless steel case withstands typical industrial environments, but avoid exposure to extreme chemicals not compatible with PPS or Viton. The Viton O-ring maintains seal integrity; replace if leakage is suspected. For maximum reliability, operate the system within the specified temperature range of +18°C to +27°C (+64°F to +80°F) at altitudes up to 2000 meters.

Compatibility & Integration

The 330104-00-16-05-02-CN is part of the 3300 XL 8 mm proximity probe family and works exclusively with 3300-series 5 mm or 3300 XL 8 mm Proximitor sensors and extension cables. It accepts a -17.5 Vdc to -26 Vdc power supply with non-incendive circuit connection per installation drawing 140979, consuming 12 mA maximum. For barrier installations, the supply range narrows to -23 Vdc to -26 Vdc. The system output resistance is 50 Ω, and supply sensitivity is less than 2 mV change per volt change in input voltage. Performance characteristics apply only to systems using solely 3300 XL 8 mm components with an AISI 4140 steel target.

Selection Guide & Purchasing Advice

Before ordering the 330104-00-16-05-02-CN, verify the unthreaded length (00 mm), overall case length (16 mm), and total length (0.5 meter) match your installation requirements. The Country Specific Approval (CN) option indicates compliance with local regulations. For replacement or upgrade from older 5 mm probes, confirm compatibility with existing extension cables and Proximitor sensors. plcmatrix.com stocks this Bently Nevada proximity probe and can advise on current lifecycle status and availability.
