FAQ

Q1. What does this “330102” part number represent?
A: It’s part of the Bently Nevada 3300 XL sensor family, representing an eddy‑current vibration/proximity sensor probe that measures

 small motions of a shaft or other conductive machinery part without contact. These are used with a

Proximitor amplifier and monitoring system.

Q2. How does the sensor measure vibration?
A: The sensor tip creates an alternating magnetic field. As a conductive target (like a shaft) moves closer or farther,

the induced eddy currents change. Those changes are converted into a voltage signal related to the

 gap and dynamic motion, providing vibration and displacement data.

Q3. What does the “CN” suffix mean?
A: The “CN” indicates the model has China‑specific regulatory compliance or agency approvals suited

 for installations requiring local certification (e.g., Chinese hazardous‑area markings). Vendor‑specific

datasheets sometimes include regional approval details.
