Bently Nevada 330980-51-CN NSv Proximitor Sensor for Reliable Machine Monitoring
Key Technical Specifications of the 330980-51-CN
The 330980-51-CN belongs to the 3300 XL NSv series. This Proximitor Sensor accepts one noncontacting 3300 RAM or 3300 NSv proximity probe. It also works with an extension cable. Power requirements range from -17.5 Vdc to -26 Vdc without barriers. Maximum current draw is 12 mA. With barriers, use -23 Vdc to -26 Vdc.
Operation above -23.5 Vdc reduces the linear range. Therefore, check your power supply carefully. Supply sensitivity stays below 2 mV change per volt of input change. Output resistance is 50 Ω.
Additionally, the 330980-51-CN model has a total system length of 5.0 meters (16.4 feet). The “51” suffix confirms this length and the DIN mounting option. The “CN” suffix indicates country-specific agency approval.
Mechanical and Environmental Ratings
The Proximitor Sensor housing uses A380 aluminum. Its weight is 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 can reach 100% condensing. However, do not submerge the sensor when connectors are unprotected. The device passes IEC 68-2-3 damp heat testing.
Installation and Mounting Flexibility
Users can mount the 330980-51-CN in two ways. First, install it on a high-density DIN rail. Second, use a traditional panel mount configuration. SpringLoc terminal strips require no special tools. This design enables faster and more robust field wiring.
Furthermore, the improved RFI/EMI immunity helps achieve European CE mark approval. No special mounting steps are needed. Nearby high-frequency radio signals will not affect the transducer system. For best accuracy, use a Bently Nevada AISI 4140 steel target (31 mm diameter or larger). Set the probe gap at 1.0 mm (40 mils).

Frequently Asked Questions (FAQ)
1. Can I use the 330980-51-CN with any 8mm probe?
Yes, it works with 3300 RAM and 3300 NSv proximity probes. Do not use other probe types.
2. What happens if my power supply is above -23.5 Vdc?
Operation above -23.5 Vdc reduces the linear range. You may get inaccurate measurements.
3. Does this sensor work in high humidity areas?
Yes, it handles 100% condensing humidity. However, protect all connectors from submersion.
4. How do I mount the 330980-51-CN on a DIN rail?
Simply clip the sensor onto a standard DIN rail. SpringLoc terminal strips then secure wiring without tools.
5. Is the Bently Nevada 330980-51-CN CE certified?
Yes, its high RFI immunity allows CE mark approval without special mounting considerations.
