Why Choose This 3300 NSv Probe?
The Bently Nevada 330905-05-10-05-01-00 is engineered for harsh environments where chemical resistance is critical. Its side-view characteristics outperform the 3000-series 190 probe, ensuring accurate gap measurements even at close distances. The probe supports field wiring up to 305 meters (1,000 feet) between the sensor and monitor, with a frequency response of 0 to 10 kHz. This makes it a robust choice for continuous vibration monitoring in process compressors, turbines, and other rotating equipment.
Installation & Setup Guidance
For optimal performance, mount the probe with the recommended torque of 0.56 N•m (5 in•lb) – finger tight is acceptable. Ensure the target surface is flat and at least 8.9 mm (0.35 in) in diameter; for axial measurements on shafts smaller than 13 mm (0.5 in), expect scale factor changes and adjust gap accordingly. Use three-conductor shielded triad cable for field wiring, with conductor sizes from 0.2 to 1.5 mm² (16 to 24 AWG). Maintain the minimum bend radius of 25.4 mm to prevent cable damage.
Maintenance & Reliability
Regularly inspect the probe tip and cable for wear or chemical attack. The 3300 NSv probe's PPS tip and stainless steel case provide excellent resistance to process contaminants. Check the connector torque periodically to ensure secure connections. With proper care, this probe delivers consistent, accurate measurements, reducing unplanned downtime and extending machinery life.
Compatibility & Integration
The 330905-05-10-05-01-00 is compatible with Bently Nevada 3300 XL NSv Proximitor Sensors and monitors. It is also interchangeable with previous 3300 RAM probes, simplifying upgrades. The probe works with standard 75 Ω coaxial cable and supports field wiring lengths up to 305 meters, making it easy to integrate into existing monitoring systems.
