Features:
- 3/8-24 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 330909-00-20-05-02-05 is engineered with a 3/8-24 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 a compact overall case length of 2.0 inches and a 0.5 meter total length, this probe provides the reach needed for standard installations while maintaining the ruggedness required for long-term reliability.
The 330909-00-20-05-02-05 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 330909-00-20-05-02-05 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 330909-00-20-05-02-05 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).

- Typical Equipment: Centrifugal air compressors, refrigeration compressors, small process gas compressors, and pumps.
- Radial Vibration and Position: 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).
- Corrosion Resistance: Employs a Polyphenylene Sulfide (PPS) probe tip, offering superior chemical stability compared to the older RAM system, suitable for compressor environments containing corrosive gases.
- Pressure Seal: Features an internal pressure seal, but continued exposure below may impair its performance.
- Hazardous Areas: The 05 at the end of the code indicates multi-national explosion-proof certifications (such as CSA, ATEX, IECEx), suitable for Zone 0/Class 1 flammable and explosive environments.
- Integrated Monitoring System 3500: Typically integrated with the Bently Nevada 3500 mechanical protection system for automatic alarms, shutdown protection, and status diagnostics.
- RFI/EMI Protection: The system features improved RF interference immunity, ensuring stable signal in complex electromagnetic environments.
- Control Parameter Analysis: This model (330909) uses 3/8-24 UNF threads with stainless steel armor. The probe cable length is 0.5 meters. Appropriate extension cables must be used during system circuit wiring to ensure a consistent total system length (typically 5 or 7 meters).
