Frequently Asked Questions

• Q: What is a reverse mount probe and when to use it?
  A: Reverse mount probes install from inside the machine casing outward. Use for thrust position measurement, limited access areas, or when standard mounting from outside is not possible due to space constraints.
• Q: What approvals does option 05 include?
  A: Multiple Approvals include CSA (North America), ATEX (Europe), and IECEx (international) for global hazardous location use.
• Q: Why no case length option on this probe?
  A: Reverse mount probes have fixed case length (threads run to tip). The 146055 series is designed for reverse mounting where adjustable case length is not needed.
• Q: Can I use this probe with standard 3300 XL proximitors?
  A: Yes. This is a 3300 series ceramic reverse mount probe compatible with 3300 XL proximitors (model 330180-90-00).
• Q: What is the advantage of ceramic tip for reverse mount?
  A: Alumina ceramic tip provides exceptional wear resistance. In reverse mount applications, the probe tip may face abrasive conditions - ceramic withstands wear better than standard PPS tips.
