Bently Nevada 330104-00-09-10-11-CN 3300 XL 8 mm Proximity Probe

Introduction

As industrial machinery evolves toward higher speeds and tighter tolerances, the need for precise, non-contact vibration monitoring has never been greater. The Bently Nevada 330104-00-09-10-11-CN, part of the 3300 XL 8 mm proximity probe series, addresses this challenge with a robust design engineered for continuous operation in harsh environments. Whether monitoring steam turbines, centrifugal compressors, or large pumps, this probe delivers the accuracy and durability that maintenance professionals rely on to prevent unplanned downtime.

Technical Specifications Breakdown

The 330104-00-09-10-11-CN features an M10 x 1 thread with armor for enhanced mechanical protection in high-vibration areas. Its unthreaded length is 00 mm, overall case length is 09 mm, and total length is 1.0 meter (3.3 feet). The probe tip is made of polyphenylene sulfide (PPS), a material chosen for its chemical resistance and electrical insulation properties. The probe case is constructed from AISI 303 or 304 stainless steel (SST), providing corrosion resistance in demanding industrial settings. Nominal probe DC resistance from center conductor to outer conductor is 7.59 ± 0.50 Ω at 1.0 m length. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring, ensuring reliable operation in pressurized environments.

Industry Applications

In power generation, the 330104-00-09-10-11-CN is commonly installed on turbine bearing housings to measure shaft vibration and position. Its 8 mm diameter and 1.0 m cable length suit tight installations where space is limited. In oil and gas facilities, the armored M10 x 1 thread withstands constant mechanical stress from rotating equipment, reducing the risk of cable fatigue. The miniature coaxial ClickLoc connector with connector protector and FluidLoc cable ensures a secure, moisture-resistant connection even in wash-down areas.

Installation & Setup Guidance

Proper mounting is critical for accurate readings. Install the probe using the M10 x 1 thread into a pre-tapped hole, ensuring the probe tip is perpendicular to the target surface. Gap the probe at 1.27 mm (50 mils) when using an AISI 4140 steel target for optimal linear range. Use the supplied miniature coaxial ClickLoc connector to attach the extension cable; the connector protector prevents damage during installation. Verify that the probe cable is routed away from sharp edges and high-temperature surfaces to avoid abrasion or thermal degradation.

Maintenance & Reliability

Routine inspection of the probe tip and cable for wear or contamination helps maintain measurement accuracy. The PPS tip resists many chemicals, but periodic cleaning with a soft, dry cloth is recommended. Check the Viton O-ring seal integrity if the probe is exposed to pressure cycling. The stainless steel case and armored thread provide long service life in most industrial environments. For best reliability, follow the manufacturer's guidelines for cable bend radius and avoid exceeding the probe's rated pressure differential.

Buying Guide & Selection Advice

When ordering the 330104-00-09-10-11-CN, verify that the total length (1.0 m) and connector type (miniature coaxial ClickLoc with FluidLoc cable) match your system requirements. This probe is designed for use with 3300 XL 8 mm Proximitor sensors and extension cables.
