Performance specifications are based on a system with extension cable and probe between 0°C and +45°C (+32°F to +113°F) at a maximum altitude of 2000 m, with a -24 Vdc power supply, a 10 kΩ load, a Bently Nevada supplied AISI 4140 steel target (31 mm diameter or larger), and a probe gap of 1.0 mm (40 mils). System accuracy and interchangeability do not apply when calibrated to other targets.
Key Benefits
-
Enhanced RFI/EMI immunity prevents nearby high-frequency radio signals from affecting transducer performance.
-
Compact, thin design enables mounting in high-density DIN-rail installations or traditional panels.
-
SpringLoc terminal strips require no special tools, allowing faster and more robust field wiring connections.
-
CE mark approved without special mounting considerations, reducing installation complexity.
Applications
The Bently Nevada 330980-70-00 is widely used in rotating machinery monitoring, including turbines, compressors, pumps, and motors. It provides accurate shaft vibration and position measurements essential for predictive maintenance and protection systems. In high-vibration environments, the sensor's RFI immunity ensures reliable data acquisition, minimizing false trips and unplanned downtime. Its panel-mount design suits retrofit projects where space is limited, making it a preferred choice for upgrading legacy monitoring systems.
Installation & Setup Guidance
When installing the 330980-70-00, ensure the mounting surface is clean and flat. For DIN-rail mounting, use a standard 35 mm rail; for panel mounting, secure the sensor using appropriate screws. Connect the probe and extension cable to the sensor input, tightening the SpringLoc terminals securely—no special tools are required. Verify the power supply voltage is within -17.5 Vdc to -26 Vdc (without barriers) or -23 Vdc to -26 Vdc (with barriers). Maintain a probe gap of 1.0 mm (40 mils) to achieve specified accuracy. Avoid operating above +45°C for optimal performance, and protect connectors from condensation to maintain humidity ratings.
Maintenance & Reliability
Routine inspection of the sensor and cabling is recommended every six months. Check for physical damage, loose connections, and signs of corrosion. The A380 aluminum housing provides excellent thermal conductivity and durability. Because the sensor operates in harsh environments, ensure connectors remain sealed to prevent moisture ingress. Calibration should be verified annually using a Bently Nevada AISI 4140 steel target to maintain system accuracy. Proper maintenance extends service life and reduces lifecycle costs, making the 330980-70-00 a cost-effective solution for continuous monitoring.
Selection Guide & Purchasing Advice
Before purchasing, confirm the system length (7.0 meters) and mounting option (panel mount) match your application requirements. Verify that your existing probe and extension cable are compatible (3300 RAM or 3300 NSv). If barriers are used, ensure the power supply meets the -23 Vdc to -26 Vdc range.
