Bently Nevada 330902-00-10-10-01-05 3300 NSv Proximity Probe

Description

330902-00-10-10-01-05: 3300 NSv proximity probe, 1/4-28 UNF thread with armor, Option 00 fully threaded, Option 10 with 1.0 inch case length, Option 10 with 1.0 meter total cable length, Option 01 ClickLoc connector with protector, and Option 05 Multiple Approvals.

This probe belongs to the 3300 XL NSv Proximity Transducer System, which is used for applications with limited clearance or reduced target areas, such as small-bore machinery or aeroderivative gas turbines. While the base model 330902 includes robust stainless steel armor to protect the coaxial cable from abrasive environments, other configurations like the 330901 are non-armored. Furthermore, this specific configuration includes option 01 for the connector, providing an integrated fluorosilicone connector protector that seals the ClickLoc connection against fluid ingress, unlike option 02 which comes without a connector protector.

Features

• Integrated stainless steel armor provides physical protection for the 75 ohm coaxial probe cable in harsh mechanical environments.
• Fully threaded 1/4-28 UNF case (Option 00 unthreaded, Option 10 case length) allows precise mounting depth adjustment in 1.0 inch total thread length.
• Total length of 1.0 meter (Option 10) allows compact sensor connection when matched with the appropriate extension cable.
• ClickLoc miniature coaxial connector with pre-installed fluorosilicone connector protector (Option 01) seals against moisture and industrial fluids.
• Multiple hazardous area approvals (Option 05) enable deployment under ATEX, IECEx, and North American intrinsically safe regulations.

Applications

• Radial vibration and axial position measurements on high-speed rotating shafts with small target geometries under 20 mm (0.8 inches).
• Aeroderivative gas turbines, centrifuges, and small-bore industrial compressors.
• Tight-clearance machinery installations where conventional 8 mm probes cannot fit.

Installation Guidelines

• Ensure the target area meets the minimum recommended shaft diameter of 20 mm (0.8 inches) to avoid scale factor degradation.
• Avoid mounting probes in counterbores smaller than 13 mm (0.5 inches) unless linear range reduction is acceptable.
• Tighten the 1/4-28 UNF-2A thread using a torque wrench, maintaining standard engineering limits for AISI 304 stainless steel.
• Ensure the total system length (sum of probe and extension cable) equals the calibrated Proximitor system length (typically 5.0 or 7.0 meters).
• Protect the ClickLoc miniature coaxial connection using the integrated fluorosilicone connector protector to prevent fluid ingress and high-impedance paths.
