The Bently Nevada 330780-50-00 belongs to the trusted 3300 XL series. This model uses an 11 mm Proximitor Sensor design. Its thin housing allows flexible mounting in high-density DIN-rail or panel setups. Improved RFI immunity helps it meet European CE mark standards without extra shielding. Additionally, this sensor protects against nearby high-frequency radio signals. The SpringLoc terminal strips simplify field wiring. For instance, you do not need special tools for installation. As a result, the Bently Nevada 330780-50-00 saves time and ensures robust connections. The factory calibration applies to AISI 4140 steel. However, you can request other target material calibrations.
This sensor accepts one non-contacting 3300 XL 11 mm probe and extension cable. Power requirements range from -17.5 Vdc to -26 Vdc without barriers. Maximum consumption sits at 12 mA. For barriers, use -23 Vdc to -26 Vdc. Operation above -23.5 Vdc may reduce linear range. Supply sensitivity is less than 2 mV change per volt change. Output resistance measures 50 Ω. The system length totals 5.0 meters, including extension cable. This matches the panel mount option. Therefore, the 330780-50-00 delivers stable performance for long-term monitoring.
The Proximitor Sensor uses A380 aluminum material. Its operating temperature ranges from -52°C to +100°C (-62°F to +212°F). Storage temperature goes from -52°C to +105°C (-62°F to +221°F). Relative humidity tolerance reaches 100% condensing. Nevertheless, do not submerge the unit when connectors are unprotected. The sensor passes IEC 68-2-3 damp heat testing. Dimensions are approximately 6.35 cm x 6.12 cm x 8.13 cm. This compact footprint fits easily into crowded cabinets.
First, choose a panel or DIN-rail location away from strong RF sources. Next, secure the Proximitor Sensor using standard mounting hardware. Then, connect the 3300 XL 11 mm probe and extension cable to the SpringLoc terminals. These terminals require no special tools. Moreover, the panel mount version of Bently Nevada 330780-50-00 provides a stable base for permanent installation. Ensure the power supply delivers clean -17.5 Vdc to -26 Vdc. Avoid voltages more positive than -23.5 Vdc for full linear range. Finally, verify the probe gap and output signal before system startup.
This series shares advanced features with the 8 mm Proximitor Sensor. However, the 11 mm version offers a thinner design. It fits high-density installations easily. Additionally, the improved RFI/EMI immunity prevents false triggers from nearby radios. The SpringLoc terminal strips speed up wiring by 30% compared to screw terminals. Many plants use 330780-50-00 for steam turbines, compressors, and large pumps. Consequently, downtime decreases while machine protection increases. Furthermore, Bently Nevada backs every sensor with rigorous factory testing.

1. Can I use the Bently Nevada 330780-50-00 with a 9m system length?
No, this specific model has a fixed 5.0 meter total length including extension cable. For 9m, choose the 330780-90-00 variant.
2. Does this sensor work with non-AISI 4140 steel targets?
Yes, but factory calibration defaults to AISI 4140 steel. You may request custom calibration for other materials before ordering.
3. What happens if I supply -24 Vdc instead of -17.5 Vdc?
That is acceptable. The range is -17.5 Vdc to -26 Vdc without barriers. However, avoid voltages more positive than -23.5 Vdc to keep full linear range.
4. Is the 330780-50-00 suitable for outdoor use?
Yes, but protect all connectors from submersion. The sensor tolerates 100% condensing humidity when connectors are properly sealed.
5. How do I clean the Proximitor Sensor?
Use a dry, lint-free cloth. Do not use solvents or high-pressure water. Also, avoid touching the internal terminals to prevent static damage.
