Professional FAQ & Selection Guide

• How do I verify the correct penetration depth for my specific machine?
  Penetration (-059) must account for the machine casing thickness plus the required gap to the target shaft. Measure from the mounting boss surface to the shaft face and subtract the standoff length.
• Why is the 2.5-inch standoff adapter (-25) necessary for this assembly?
  The standoff adapter allows the use of standard-length probes in deep-seated mounting locations and provides a mechanical reference point for zeroing the probe gap.
• Can I use a 5mm probe with the 24701-16 housing?
  No. The -16 option is specifically machined for the 8mm 3300 XL probe body. Using a different probe diameter will result in poor sealing and incorrect vibration readings.
• What is the advantage of using a 0.5-meter cable length (-05)?
  Short internal leads prevent excessive cable “whip” inside the housing, reducing signal noise and making the final connection to the extension cable more manageable.
• Is the dome cover explosion-proof rated?
  The 24701 series is designed to meet stringent industrial standards; however, always ensure your conduit fittings (-04 option) match the local hazardous area classification for the full installation.
