Overview Manuals Specifications Applications Protection Installation Notes

Features:

  • 1/4-28 UNF thread with armor protection provides enhanced mechanical durability for standard UNF mounting applications in harsh industrial environments.
  • Increased chemical resistance compared to 3300 RAM probes enables reliable operation in process compressor applications with exposure to aggressive media.
  • Superior side-view characteristics versus 3000-series 190 probes allow accurate measurements in confined spaces where optimal probe orientation is limited.
The 330902-00-38-05-02-05 is engineered with a 1/4-28 UNF thread and full armor protection, delivering exceptional mechanical durability for demanding industrial environments. The armored construction shields the probe against crushing, abrasion, and impact damage during installation and operation—critical in heavy machinery applications such as compressors, turbines, and large rotating equipment. With an overall case length of 3.8 inches and a 0.5 meter total length, this probe provides the reach needed for deeper installations while maintaining the ruggedness required for long-term reliability.

The 330902-00-38-05-02-05 offers significantly increased chemical resistance compared to the previous 3300 RAM probe designs, making it ideally suited for process compressor applications where exposure to aggressive media is a daily reality. In environments such as natural gas compression, chemical processing, and refinery operations, probes are routinely exposed to sour gas, corrosive vapors, lubricating oils, and chemical solvents that can degrade standard materials over time.

The 330902-00-38-05-02-05 delivers superior side-view characteristics compared to the 3000-series 190 probe when gapping at the same distance from the probe target—a critical advantage in applications where space constraints limit optimal probe orientation. In tightly packed machinery such as centrifugal compressors, steam turbines, and gearboxes, achieving perfect perpendicular alignment between probe and target is often physically impossible.

The 330902-00-38-05-02-05 Bently Nevada 3300 NSv Proximity Probes may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Radial Vibration and Displacement: Suitable for thin shafts with a diameter less than 51 mm (2 in).
  • Axial (Thrust) Position: Suitable for small planar targets with a diameter less than 15 mm (0.6 in).
  • Hazardous Area Protection: CSA, ATEX, and IECEx certified, suitable for Zone 0/Class 1 or Zone 2/Class 2 hazardous environments.
  • Chemical Resistance: Compared to the older RAM probe, the NSv offers superior resistance to chemical corrosion.
  • ClickLoc Connector: The metal ClickLoc connector features a locking mechanism to prevent loosening under vibration.
  • Tightening Torque: Do not overtighten during installation. A maximum torque of 65 in-lb is recommended.
  • Thread Fit: The maximum thread engagement length is typically 1.5 times the nominal diameter to prevent jamming during installation.
  • Gap Adjustment: Ensure the initial gap voltage between the probe face and the target is within the linear range required by the system.
Description
The 330902-00-38-05-02-05 features a 1/4-28 UNF thread configuration with armor protection, providing enhanced durability for demanding industrial installations requiring standard UNF mounting threads. This model includes a 0.5 meter (20 inch) total length with an overall case length of 3.8 inches and unthreaded length of 0.0 inches.
