FAQ

1. What is a Bently Nevada proximity probe used for?

A proximity probe is used in industrial condition monitoring to measure the distance between a rotating shaft and the probe tip without physical contact. This data can be processed for vibration analysis, shaft position monitoring, speed detection, and early fault detection in machinery.

2. What does the part number 330103-00-05-05-02-CN mean?

The Bently Nevada part numbering denotes configuration options:

• 330103: 3300 XL series 8 mm probe

• 00: No unthreaded section

• 05: Probe case length (typically ~50 mm)

• 05: Cable length (approx. 0.5 m)

• 02: ClickLoc miniature coaxial connector

• CN: Country-specific certification (e.g., China approvals) Options may vary by region and spec sheet.

3. How does this proximity probe work?

The probe generates an eddy current field near a conductive surface (e.g., a shaft). As the distance changes between the probe tip and target,

 the impedance changes and produces a voltage signal proportional to displacement. A Proximitor sensor

 amplifier then conditions that signal for monitoring systems.
