Frequently Asked Questions (FAQ)

• Is this probe fully compatible with older 3300 RAM systems?
  Yes, the 3300 NSv probe is mechanically and electrically interchangeable with the previous 3300 RAM probe.
• What happens if my target shaft diameter is smaller than 13 mm?
  The scale factor may change, but reducing the gap helps limit this effect.
• Can I use this probe without a target at exactly 1.0 mm gap?
  Yes, 1.0 mm (40 mils) is the recommended gap for optimal linear performance.
• Does the probe require special field wiring for long distances?
  Yes, use three-conductor shielded triad cable for runs up to 305 meters.
• Is this item new and in stock?
  Yes, we guarantee a new and original unit with factory packing in stock.
• What is your return policy for this proximity probe?
  We accept returns within 30 days from the delivery date.
