330980-51-05 Bently Nevada NSv Proximitor Sensor
The 330980-51-05 belongs to Bently Nevada's 3300 XL NSv series. Industrial facilities use this sensor for noncontact vibration and position monitoring. Its thin housing supports both DIN rail and traditional panel mount configurations. Additionally, the sensor delivers strong resistance to radio frequency interference. Therefore, it achieves CE mark approval without extra shielding.
Key Technical Specifications of the 330980-51-05
The 330980-51-05 accepts one noncontacting 3300 RAM or 3300 NSv proximity probe. It also works with a compatible extension cable. Power requirements range from -17.5 Vdc to -26 Vdc without barriers. With barriers, you need -23 Vdc to -26 Vdc. Operation at voltages more positive than -23.5 Vdc reduces the linear range. Supply sensitivity stays below 2 mV change per volt of input change. Output resistance is 50 Ω.
Furthermore, the system uses a -24 Vdc power supply for standard operation. A 10 kΩ load is typical. Bently Nevada specifies an AISI 4140 steel target of 31 mm diameter or larger. The probe gap is set at 1.0 mm (40 mils) during calibration. System accuracy applies only when using this target. For other targets, performance may vary significantly.
Mechanical and Environmental Ratings
The 330980-51-05 Proximitor Sensor weighs 255 g (9 oz). Its enclosure uses A380 aluminum. Operating temperature ranges from -52°C to +100°C (-62°F to +212°F). Storage temperature goes from -52°C to +105°C. Relative humidity tolerance is 100% condensing. However, connectors must stay protected from direct submersion. The device passed IEC 68-2-3 damp heat testing.
Installation and Mounting Guidance
This model includes the 51 suffix, which means 5.0 meters (16.4 feet) system length and DIN rail mounting. The 05 suffix indicates a specific agency approval option. The SpringLoc terminal strips require no special tools. Consequently, field wiring becomes faster and more robust. You can also mount the sensor in a traditional panel configuration. For high-density installations, the slim design saves significant cabinet space. First, secure the DIN rail to your enclosure. Next, clip the sensor onto the rail. Finally, connect the probe and extension cable. Always verify the power supply voltage before connection.
Why Choose the 3300 XL NSv Series
The 330980-51-05 shares core features with the 3300 XL 8 mm Proximitor Sensor. However, its thinner profile allows more flexible placement in crowded panels. Improved RFI/EMI immunity prevents nearby radio signals from affecting readings. This makes it suitable for variable frequency drive environments. Moreover, the sensor works without special mounting considerations for CE approval. Many users prefer this model for retrofit projects or new turbine monitoring systems.

Frequently Asked Questions (FAQ)
1. Can I use the 330980-51-05 with a non-Bently Nevada target?
Yes, but system accuracy and interchangeability specifications only apply with a Bently Nevada AISI 4140 steel target. Other targets may reduce linear range.
2. What happens if I supply -24 Vdc instead of -23.5 Vdc?
Operation at -24 Vdc is perfectly acceptable. However, voltages more positive than -23.5 Vdc (for example -22 Vdc) will reduce the linear measurement range.
3. Does the 330980-51-05 include the proximity probe?
No. The 330980-51-05 is only the Proximitor Sensor. You must order a 3300 NSv proximity probe and extension cable separately.
4. Can this sensor work in condensing humidity environments?
Yes, it tolerates 100% condensing humidity. Nevertheless, you must protect all connectors from direct submersion to avoid damage.
5. What is the advantage of SpringLoc terminal strips over screw terminals?
They eliminate special tools completely. Additionally, they create highly robust field wiring connections. This reduces installation time significantly and improves long-term reliability.
