Bently Nevada 330902-05-30-10-02-05 3300 XL NSv Proximity Probe

Description

The 330902-05-30-10-02-05 is a 3300 XL NSv proximity probe featuring a 1/4-28 UNF thread and protective stainless steel armor. This specific configuration includes a 0.5-inch unthreaded length (Option 05), a 3.0-inch case length (Option 30), and a 1.0-meter system length (Option 10). Designed for environments with restricted installation space, it utilizes a standard miniature coaxial ClickLoc connector (Option 02) and comes with multiple agency approvals (Option 05) for hazardous area operation.

The 3300 XL NSv transducer system is optimized for machinery where traditional 5 mm or 8 mm probes cannot be used due to counterbore, side-view, or rear-view limitations. This model is commonly used for radial vibration, axial position, and speed measurements on small-bore equipment, including aeroderivative turbines and high-speed centrifugal compressors. The armored construction provides enhanced mechanical protection in industrial environments, while the NSv design ensures accurate signal output for target diameters as small as 15 mm.

Features

• 1/4-28 UNF threaded probe with stainless steel armor for added durability
• 0.5-inch unthreaded length and 3.0-inch total case length
• 1.0-meter probe lead with standard miniature coaxial ClickLoc connector
• Certified with Multiple Approvals (Option 05) for hazardous location compatibility
• Optimized for small-target applications and tight clearance installations
• Compatible with standard 3300 XL NSv Proximitor sensors and extension cables

Applications

• Radial vibration and radial position measurements on small-bore machinery
• Axial (thrust) position measurements on equipment with limited target area
• Tachometer and zero speed measurements
• Phase reference (Keyphasor) signals on high-speed equipment
• Fluid-filmed bearing monitoring in compressors and turbines

Installation Guidelines

Ensure the probe is installed with the correct torque; finger-tighten followed by a minor adjustment is typically recommended for 1/4-28 UNF probes to avoid binding. The probe tip must not be subjected to high-pressure differentials beyond specifications. Ensure that the Proximitor sensor is installed in an environment with at least IP54 protection, particularly in hazardous areas. Use Bently Nevada-approved connector protectors when routing cables through potentially abrasive or wet areas to ensure system longevity.
