Frequently Asked Questions (FAQ)

• Can I use this probe with a 3300 XL 5 mm Proximitor?
  Yes, the 330103-00-11-50-02-05 specifically matches 5‑meter Proximitor sensors only.
• What tools do I need for installation?
  A standard M10x1 tap and torque wrench; avoid over‑tightening beyond 15 mm thread engagement.
• Is the probe submersible?
  It seals differential pressure, but we do not factory‑test the seal. Consult Bently Nevada for high‑pressure submergence.
• Does it work with 24 Vdc systems?
  Yes, it interfaces with standard −18 to −24 Vdc Proximitor outputs.
