Frequently Asked Questions (FAQ)

• Q: Is the 330910-05-25-10-02-00 fully interchangeable with the 3300 RAM probe?
  A: Yes, the 3300 NSv probe and extension cable are mechanically and electrically interchangeable with the previous 3300 RAM series.
• Q: What is the maximum frequency response with long field wiring?
  A: The probe delivers 0 to 10 kHz response typically with up to 305 meters of field wiring – see frequency rolloff graphs.
• Q: Can I use this probe both for axial and radial vibration?
  A: Yes, the 3300 NSv probe works for axial position measurements, but reduce gap for shaft diameters under 13 mm.
• Q: What happens if I exceed the recommended torque?
  A: Exceeding 0.56 N•m (5 in•lb) may damage the probe case or threads; always follow torque specs.
• Q: Are these probes pressure tested before shipment?
  A: No, Bently Nevada does not pressure test them. Contact their custom design department if you need a seal test.
• Q: Is the probe tip resistant to harsh chemicals?
  A: Yes, the PPS tip and Viton O-ring provide increased chemical resistance for process compressors.
