Introduction to the 330980-70-00 NSv Proximitor Sensor
When machine vibration threatens uptime, the 330980-70-00 from Bently Nevada provides a dependable sensing solution. This NSv Proximitor Sensor is engineered for continuous monitoring in demanding industrial environments. It accepts a noncontacting 3300 RAM or 3300 NSv proximity probe and extension cable, converting probe signals into usable data for protection and diagnostics.
The 330980-70-00 features a 7.0-meter (23.0 feet) system length and a panel mount option, making it suitable for retrofit or new installations. Its thin design allows mounting in high-density DIN-rail or traditional panel configurations, giving maintenance engineers flexibility during setup.
Key Features and Technical Specifications
This Proximitor Sensor delivers consistent performance across a wide temperature range. It operates from -52°C to +100°C (-62°F to +212°F) and stores safely from -52°C to +105°C (-62°F to +221°F). The sensor withstands 100% condensing humidity when connectors are protected, tested to IEC 68-2-3 damp heat.
- Power requirement: -17.5 Vdc to -26 Vdc without barriers, -23 Vdc to -26 Vdc with barriers, at 12 mA maximum consumption.
- Output resistance: 50 Ω.
- Sensitivity: Less than 2 mV change in output voltage per volt change in input voltage.
- Proximitor Sensor material: A380 aluminum.
- Proximitor Sensor weight: 255 g (9 oz).
Improved RFI/EMI immunity allows the 330980-70-00 to achieve European CE mark approvals without special mounting considerations. This immunity also prevents nearby high-frequency radio signals from adversely affecting the transducer system.
Installation and Setup
SpringLoc terminal strips on the Proximitor Sensor require no special installation tools. This design facilitates faster, highly robust field wiring connections, reducing installation time and minimizing the risk of loose connections. The panel mount option provides a stable mounting surface for permanent installations.
For optimal performance, mount the sensor in a location that avoids excessive vibration and extreme temperatures beyond the specified range. Ensure connectors are protected from condensation to maintain the humidity rating.
Maintenance and Reliability
Regular inspection of the sensor and its connections is essential for long-term reliability. Check the terminal strips periodically for tightness and signs of corrosion. Verify that the probe gap remains within the recommended range, as system accuracy depends on a probe gap of 1.0 mm (40 mils) with a Bently Nevada AISI 4140 steel target.
The sensor's robust construction and wide temperature range contribute to extended service life. Its low power consumption (12 mA maximum) reduces thermal stress, further enhancing reliability.
Compatibility and Integration
The 330980-70-00 is designed to work with Bently Nevada 3300 RAM or 3300 NSv proximity probes and extension cables. It provides a standard output resistance of 50 Ω, making it compatible with typical monitoring systems. For barrier applications, the sensor operates with -23 Vdc to -26 Vdc supply, ensuring safe integration in hazardous areas.
Troubleshooting Common Issues
If the sensor output is unstable, check the supply voltage. Operation at a more positive voltage than -23.5 Vdc can result in reduced linear range. Verify that the probe and extension cable are properly connected and that the target is a Bently Nevada AISI 4140 steel target of 31 mm (1.2 in) diameter or larger.
If RFI interference is suspected, confirm that the sensor is mounted according to guidelines. The improved RFI/EMI immunity of this model minimizes such issues, but proper grounding remains important.
