FAQ

Q1. What is the difference between a standard 3300 XL probe and a PROXPAC XL unit?
A: A standard 3300 XL probe is just the sensing tip and cable, requiring a separate Proximitor signal conditioner. A PROXPAC XL

 integrates the probe and Proximitor into a single housing, eliminating separate extension cables

 and external Proximitor modules.

Q2. What does the “8 mm” specification mean?
A: “8 mm” refers to the probe tip diameter and typical sensing range scale used in the 3300 XL family. This

size balances robustness and sensitivity for common industrial use.

Q3. What is the function of the Proximitor sensor inside this assembly?
A: The Proximitor sensor amplifies and conditions the raw signal from the eddy‑current probe so the

 output can be read directly by vibration monitors, PLCs, DCS systems,

or machine protection systems.
