The 330106-05-30-05-02-BR belongs to Bently Nevada’s trusted 3300 XL series. This 8 mm reverse mount probe fits applications where space is limited. Its compact design allows installation from behind the target. Many users choose this probe for steam turbines, compressors, and pumps. Additionally, the reverse mount configuration simplifies mechanical assembly in crowded machine trains.
The 330106-05-30-05-02-BR comes with a total length of 0.5 meter (1.6 feet). Its connector option features a miniature ClickLoc coaxial type. The agency approval option is labeled BR for country-specific requirements. Probe threads are M10x1 for this model.
For nominal DC resistance, the 330106-05-30-05-02-BR shows 7.45 ± 0.50 ohms from the center conductor to the outer conductor. The probe tip uses Polyphenylene sulfide (PPS) material. Its case is constructed from AISI 303 or 304 stainless steel (SST).
The standard cable uses 75Ω triaxial construction with fluoroethylene propylene (FEP) insulation. An extended temperature range cable is also available with perfluoroalkoxy (PFA) insulation. Optional flexible armor uses AISI 302 or 304 SST with an FEP outer jacket.
Maximum rated tensile strength reaches 330 N (75 lbf) from probe case to probe lead. At the probe lead to extension cable connectors, the rating is 270 N (60 lbf). Connector materials include gold-plated brass or gold-plated beryllium copper.
The probe case thread is M10x1 with a maximum thread engagement length of 15 mm. Probe weight measures 323 g per meter (11.4 oz per foot). For the 330106-05-30-05-02-BR with 0.5m cable, total weight is approximately 161.5 g.
Operating and storage temperatures for the standard probe range from -52°C to +177°C (-62°F to +350°F). For extended temperature range probes, the tip handles -52°C to +218°C (-62°F to +425°F). The extended cable and connector operate from -51°C to +260°C (-60°F to +500°F).
Important note: Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The 3300 XL 8 mm probe seals differential pressure between the tip and case using a Viton O-ring.
Relative humidity performance shows less than a 3% change in Average Scale Factor (ASF). This testing follows IEC standard 68-2-3 at 93% humidity for up to 56 days.
First, clean the mounting surface and threads thoroughly. Next, thread the reverse mount probe carefully into the hole. The 330106-05-30-05-02-BR uses M10x1 threads, so use matching hardware. Then tighten to the recommended torque value (refer to Bently Nevada guidelines for your specific case material). After mechanical installation, connect the miniature ClickLoc coaxial connector. You will hear a click when it locks properly. This locking feature prevents vibration-induced loosening. Finally, verify the gap voltage according to your monitoring system requirements.

1. What is the difference between standard and extended temperature range cables?
Standard FEP cables work from -52°C to +177°C. Extended PFA cables handle higher temperatures up to +260°C on the cable and +218°C at the probe tip.
2. Can I add armor to the 330106-05-30-05-02-BR?
Yes, optional flexible stainless steel armor is available for both standard and extended temperature cables. However, this requires ordering a different configuration code.
3. Why is the probe not pressure tested before shipment?
Bently Nevada does not perform routine pressure testing. Nevertheless, the Viton O-ring design seals differential pressure effectively. Contact the custom design department if your application requires a certified pressure test.
4. What happens if the temperature drops below -34°C for a long time?
The pressure seal may fail prematurely. Therefore, avoid sustained operation below -34°C (-30°F). Use the extended temperature range probe if your environment regularly sees such low temperatures.
5. Is the 330106-05-30-05-02-BR compatible with existing 3300 XL extension cables?
Yes. The 3300 XL system uses standard 75Ω triaxial cables. The miniature ClickLoc connector ensures compatibility with all 3300 XL extension cables and Proximitor sensors.
