Bently Nevada 330902-00-40-10-02-05 3300 NSv Proximity Probe

Description

330902-00-40-10-02-05: 3300 NSv armored proximity probe, featuring a 1/4-28 UNF thread, 0.0 in unthreaded length (Option 00), 4.0 in overall case length (Option 40), 1.0 m total length (Option 10), miniature ClickLoc coaxial connector (Option 02), and Multiple Approvals hazardous area agency certification (Option 05).

This eddy-current proximity probe belongs to the 3300 XL NSv system, which operates in space-constrained industrial machinery where standard 5 mm or 8 mm proximity systems cannot fit. The built-in stainless steel armor acts as a mechanical barrier protecting the 75-ohm coaxial cable from damage caused by physical impact or abrasive environments. This specific configuration pairs with the 3300 XL NSv Proximitor Sensor and appropriate extension cables to measure shaft radial vibration or axial position.

Features

• Armored cable protection: Stainless steel armor provides mechanical shield against physical wear.
• ClickLoc coaxial connector: Gold-plated brass connector lock mechanism avoids unintended disconnection.
• Thread configuration: 1/4-28 UNF threaded case with 0.0 inches unthreaded length and 4.0 inches case length.
• Cable parameters: 1.0 meter total probe length with standard FEP insulated 75-ohm coaxial cable.
• Calibration limits: Tuned for narrow physical clearances and reduced target sizes down to 9.5 mm.
• Hazardous area approval: Option 05 provides multiple certifications (CSA, ATEX, IECEx) for classified locations.

Applications

• Shaft radial vibration and axial position measurements on high-speed rotating machinery.
• Aeroderivative gas turbine installations with restricted housing space.
• Centrifugal compressors and industrial pumps requiring compact sensor geometries.
• Small-bore machinery where target size limits standard sensor placement.

Installation Guidelines

Proper installation requires clean, dry connector junctions. The miniature coaxial ClickLoc connector requires finger-tight torque (maximum 0.56 Nm or 5 in-lb) during connection. Avoid bending the armored cable below the minimum bend radius of 25.4 mm (1.0 in). Standard installation requires tapping mounting holes with a #3 or larger tap drill for 1/4-28 UNF threads. Do not exceed the maximum case torque limit of 5.1 Nm (45 in-lb) during probe case insertion.

Compliance and Certifications

Under Option 05, this probe complies with ATEX, IECEx, and CSA standards for hazardous area installation (Zone 0, 1, and 2, Div 1 and 2), with intrinsic safety parameters meeting Ui = -28V, Ii = 140 mA, Pi = 0.91W when combined with approved barriers and Proximitor sensors.
