Frequently Asked Questions

• Does this 5.0 meter 3300 NSv Proximity Probe require an extension cable?
  No. The 5.0 meter total length connects directly to your Proximitor without an extension cable.
• What is the DC resistance difference for the 5.0 meter probe?
  The 5.0 meter length measures 5.3 ± 0.7 ohms. Shorter 0.5 m versions measure 4.0 ± 0.5 ohms.
• Can I use this probe with my existing 3300 RAM extension cable?
  Yes, it is fully interchangeable. However this 5.0 m probe typically connects directly without extension.
• What is the 250 mm case length used for?
  The -25 option provides 250 mm overall case length for deeper mounting applications through thick machine casings.
• Does the 5.0 meter cable affect frequency response?
  No. The 3300 NSv maintains 0 to 10 kHz response with up to 305 meters of total wiring.
• How should I handle the long probe cable during installation?
  Maintain minimum 25.4 mm bend radius. Do not kink or crush the FEP insulated coaxial cable.
