FAQ

Q1. What exactly does this proximity probe measure?
A: It measures the distance (gap) between the probe tip and a conductive surface (usually a rotating shaft) without physical contact, providing data on both static position and dynamic vibration — essential for condition monitoring and machine protection.

Q2. What does “3300 XL 8 mm” mean?
A: “3300 XL” refers to Bently Nevada’s upgraded, robust 8 mm eddy‑current proximity transducer system; the “8 mm” specifies the diameter

of the probe tip and its design family. These systems provide high‑performance, reliable sensing

for industrial monitoring.

Q3. What is the significance of the “CN” suffix?
A: “CN” means this variant carries China‑specific approvals or regulatory compliance markings, suitable for use in

Chinese industrial environments and possibly hazardous areas. This can include

certifications required by local standards.
