Frequently Asked Questions (FAQ)

• Q: Is the 3300 NSv probe compatible with my existing 3300 RAM system?
  A: Yes. The 330903 probe is mechanically and electrically interchangeable with previous 3300 RAM probes.
• Q: What makes the NSv probe better for process compressors?
  A: The NSv probe offers increased chemical resistance and superior side-view characteristics compared to RAM and 190 probes.
• Q: What power supply do I need for this probe?
  A: Use a compatible Bently Nevada Proximitor Sensor with -24 Vdc supply for best linear performance.
• Q: Can I extend the cable length beyond 0.5 meters?
  A: Yes. Order options include 1, 5, or 7 meter total lengths. You can also add extension cables.
• Q: How does temperature affect the 330903-00-02-05-11-00?
  A: The probe operates reliably from -52°C to +177°C, suitable for extreme industrial environments.
