Frequently Asked Questions

• Is this 3300 NSv Proximity Probe compatible with my existing 3300 RAM system?
  Yes, it is fully mechanically and electrically interchangeable. You can use your current extension cables and Proximitor without modifications.
• What is the difference between part numbers 330904-00-12-05-02-00 and 330904-00-14-05-02-00?
  The only difference is the overall case length. -12 = 120 mm, -14 = 140 mm. Both use 0.5 m total cable length.
• Can I use this probe on a shaft smaller than 13 mm?
  Yes, but expect a change in scale factor. Reduce the gap to minimize this effect.
• What tools do I need for installation?
  Use finger tightening for the tip. Use a torque wrench set to 5.1 N•m for the connector-to-case installation.
• Does this probe require pressure testing?
  The Viton O-ring provides differential pressure sealing. Units ship without pressure testing. Contact us if you require certified pressure testing.
• How long does shipping take?
  FedEx and DHL deliver within 2-5 business days. UPS shipping takes 3-6 business days depending on destination.
