The Bently Nevada 330980-70-00 belongs to the advanced 3300 XL NSv series. This model provides a 7.0 meter (23.0 feet) total system length. Its thin design supports both high-density DIN-rail and traditional panel mount installations. Improved RFI/EMI immunity allows European CE mark approval without special mounting. Additionally, this immunity blocks nearby high-frequency radio signals from affecting the transducer system. The SpringLoc terminal strips require no special tools for wiring. For instance, you can complete field connections faster and more robustly. The 330980-70-00 accepts one non-contacting 3300 RAM or 3300 NSv probe and extension cable.
Power requirements range from -17.5 Vdc to -26 Vdc without barriers. Maximum current consumption sits at 12 mA. For applications with barriers, use -23 Vdc to -26 Vdc. Operation above -23.5 Vdc may reduce linear range. Supply sensitivity stays below 2 mV change per volt change. Output resistance measures 50 Ω. The system length totals 7.0 meters including the extension cable. This matches the panel mount option 70. Moreover, the Bently Nevada 330980-70-00 delivers stable output for critical machine monitoring.
Unless otherwise noted, standard specifications apply from 0°C to +45°C at a maximum altitude of 2000 m. These require a -24 Vdc supply, a 10 kΩ load, and a Bently Nevada AISI 4140 steel target of 31 mm diameter or larger. The probe gap should be 1.0 mm (40 mils). System accuracy does not apply when using a target other than AISI 4140 steel.
The NSv Proximitor Sensor uses A380 aluminum material. Its weight reaches 255 g (9 oz). 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.
First, select a panel or DIN-rail location away from strong RF sources. Next, secure the 330980-70-00 using standard mounting hardware. Then, connect the 3300 RAM or NSv probe and extension cable to the SpringLoc terminals. These terminals require no special tools. Additionally, the panel mount version 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 at 1.0 mm before system startup.
This series shares advanced features with the 3300 XL 8 mm Proximitor Sensor. However, the NSv version offers compatibility with RAM and NSv probes. Its thin design fits high-density installations easily. Furthermore, the improved RFI/EMI immunity prevents false triggers from nearby radios. The SpringLoc terminal strips speed up wiring compared to screw terminals. Many plants use Bently Nevada 330980-70-00 for steam turbines, compressors, and large pumps. Consequently, downtime decreases while machine protection increases.

1. Can I use the Bently Nevada 330980-70-00 with an 8 mm probe?
No, this NSv model specifically accepts 3300 RAM or 3300 NSv proximity probes. For 8 mm probes, choose the standard 3300 XL 8 mm Proximitor Sensor.
2. What is the difference between suffix 70 and other options?
Suffix 70 indicates a 7.0 meter system length with panel mount. Other suffixes like 50 represent 5.0 meters. Choose based on your distance requirements.
3. Does the 330980-70-00 work with non-AISI 4140 steel targets?
Yes, but factory calibration defaults to AISI 4140 steel. System accuracy specifications do not apply when using other target materials. Request custom calibration before ordering.
4. What happens if my power supply drops to -22 Vdc?
Operation at a more positive voltage than -23.5 Vdc may result in reduced linear range. Always maintain supply between -23 Vdc and -26 Vdc when using barriers.
5. Is the NSv Proximitor Sensor suitable for high-vibration areas?
Yes, the 3300 XL NSv series is designed for turbine and compressor monitoring. The A380 aluminum housing and robust SpringLoc terminals handle typical industrial vibration levels.
