The Bently Nevada 330907-05-30-05-02-05 operates within a linear range of 1.5 mm (60 mils). This range starts at approximately 0.25 mm (10 mils) from the target. It then extends from 0.25 mm to 1.75 mm (10 to 70 mils). The output voltage in this range is roughly -1 to -13 Vdc.
Additionally, the recommended gap setting for this probe is 1.0 mm (40 mils). The probe's DC resistance from the center conductor to the outer conductor (RPROBE) measures 4.0 ± 0.5 ohms for the 0.5-meter length.
For field wiring, this sensor works with 0.2 to 1.5 mm² (16 to 24 AWG) wire. When using ferrules, you should use 0.25 to 0.75 mm² (18 to 23 AWG). We recommend using a three-conductor shielded triad cable. The maximum cable length between the 3300 NSv Proximitor Sensor and the monitor is 305 meters (1,000 feet).
The probe tip material is Polyphenylene sulfide (PPS). Its case uses AISI 304 stainless steel (SST). The Bently Nevada 330907-05-30-05-02-05 has a maximum rated torque of 22.6 N•m (200 in•lb). However, the recommended installation torque is only 7.5 N•m (66 in•lb).
Furthermore, the probe case thread is M10x1 with 15 mm maximum thread engagement. The operating and storage temperature range is -52°C to +177°C (-62°F to +351°F). Be careful when exposing this probe to temperatures below -34°C (-30°F) for long periods. Such conditions may cause premature failure of the pressure seal.
The 3300 NSv reverse mount probe also seals differential pressure between the tip and case. It uses a Viton O-ring as its sealing material. This design works well in many process compressor applications.
The 330907-05-30-05-02-05 includes agency approval option 05 (Multiple Approvals). This version meets certification requirements for several international markets. Therefore, it simplifies global procurement and reduces compliance paperwork. Users can install this probe in multiple regions without re-certification.
This model uses connector option 02: Miniature coaxial ClickLoc connector with standard cable. The ClickLoc mechanism locks into place firmly. This prevents any loosening from vibration or thermal cycling. Meanwhile, the patented TipLoc molding method creates a strong bond between the probe tip and body.
Unlike the FluidLoc version (option 12), this standard cable suits general industrial environments. It works well where fluid ingress protection is not a primary concern. All transducer system components still include gold-plated brass connectors for reliable signal transmission.
First, ensure the target surface is clean and smooth before installing the Bently Nevada 330907-05-30-05-02-05. Next, apply the recommended torque of 7.5 N•m (66 in•lb). Do not exceed the maximum rated torque of 22.6 N•m (200 in•lb). Over-tightening may damage the probe case or threads.
Then, connect the probe using its miniature coaxial ClickLoc connector. Insert the connector until you hear a click. This confirms the lock is engaged. To disconnect, pull back the outer sleeve before separating the halves.
For optimal performance, set the gap at 1.0 mm (40 mils) from the target. Use a suitable gap setting tool or a calibrated proximity system. After installation, verify the output voltage falls within the -1 to -13 Vdc range.
The 3300 NSv probe offers increased chemical resistance compared to the 3300 RAM probe. This makes it suitable for many process compressor environments. Moreover, its side-view characteristics are better than those of the 3000-series 190 probe. You will notice this superiority when gapping the 330907-05-30-05-02-05 at the same distance from the target.

1. What is the difference between the 330907-05-30-05-02-05 and the -12-CN version?
This model uses standard cable (option 02) instead of FluidLoc (option 12). It also has multiple agency approvals (05) rather than country-specific CN approval.
2. Can I use this probe in a wet or oily environment?
For wet or oily conditions, we recommend the FluidLoc cable version (connector option 12). The standard cable on this model offers less fluid protection.
3. What multiple approvals does the 05 option include?
Option 05 typically includes CSA, ATEX, IECEx, and other regional certifications. Contact us for the complete approval certificate list.
4. What is the maximum extension cable length for this 3300 NSv probe?
You can use up to 305 meters (1,000 feet) of field wiring between the Proximitor Sensor and the monitor.
5. Does the 330907-05-30-05-02-05 require special shielding?
Yes, we recommend using a three-conductor shielded triad cable for best noise immunity and signal integrity.
