Bently Nevada 330980-70-CN NSv Proximitor Sensor

Bently Nevada 330980-70-CN NSv Proximitor Sensor for Precision Machine Monitoring

Key Technical Specifications of the 330980-70-CN

The 330980-70-CN comes from the 3300 XL NSv series. This Proximitor Sensor accepts one noncontacting 3300 RAM or 3300 NSv proximity probe along with an extension cable. Power requirements sit between -17.5 Vdc and -26 Vdc without barriers. Maximum current consumption is 12 mA. When using barriers, the range becomes -23 Vdc to -26 Vdc.

Operation at a voltage more positive than -23.5 Vdc reduces the linear range. Therefore, verify your power supply before installation. Supply sensitivity stays below 2 mV change per volt of input change. Output resistance measures 50 Ω.

Additionally, the 330980-70-CN model provides a total system length of 7.0 meters (23.0 feet). The “70” suffix confirms this length together with the panel mount option. The “CN” suffix indicates country-specific agency approval.

Mechanical and Environmental Ratings

The Proximitor Sensor housing uses A380 aluminum material. Total weight reaches 255 g (9 oz). Operating temperature spans from -52°C to +100°C (-62°F to +212°F). Storage temperature extends from -52°C to +105°C (-62°F to +221°F).

Relative humidity can reach 100% condensing conditions. However, do not submerge the sensor when connectors remain unprotected. This device passes IEC 68-2-3 damp heat testing.

Installation and Mounting Flexibility

Users can mount the 330980-70-CN in two ways. First, install it on a high-density DIN rail. Second, choose the traditional panel mount configuration as indicated by the “70” suffix. SpringLoc terminal strips need no special installation tools. This design enables faster and more robust field wiring connections.

Furthermore, improved RFI/EMI immunity helps achieve European CE mark approval. No special mounting considerations are required. Nearby high-frequency radio signals will not adversely affect the transducer system. For best accuracy, always use a Bently Nevada AISI 4140 steel target with 31 mm diameter or larger. Set the probe gap exactly at 1.0 mm (40 mils).

Why Choose the 330980-70-CN for Your Application

This sensor works well in turbines, compressors, and pumps. The 7.0 meter length gives extra reach for remote installations. Panel mount configuration suits existing control cabinets. Moreover, the slim design saves valuable panel space.

The Bently Nevada 330980-70-CN also performs reliably in extreme temperatures. From cold outdoor environments to hot machinery compartments, this sensor delivers consistent data. High humidity conditions up to 100% condensing pose no problem when connectors stay protected.

Frequently Asked Questions (FAQ)

1. What is the difference between 330980-51-CN and 330980-70-CN?
The 330980-51-CN has a 5.0 meter length with DIN mount. The 330980-70-CN offers a 7.0 meter length with panel mount.

2. Can I use this sensor with a non-Bently Nevada target?
Yes, but system accuracy and interchangeability specifications no longer apply. Bently Nevada recommends their AISI 4140 steel target for best results.

3. Does the 330980-70-CN require special wiring tools?
No. SpringLoc terminal strips on the 330980-70-CN need no special installation tools. This makes field wiring fast and robust.

4. What happens if my power supply drops below -26 Vdc?
The sensor may not function correctly. Always stay within -17.5 Vdc to -26 Vdc without barriers, or -23 Vdc to -26 Vdc with barriers.

5. Is this sensor CE certified for European use?
Yes. Improved RFI/EMI immunity allows the 330980-70-CN to achieve European CE mark approval without any special mounting considerations.
