FAQ

Q1. What is a proximity probe and what does it measure?

A proximity probe is a non‑contact displacement sensor that uses eddy‑current principles to measure the distance between the probe tip and a conductive surface (typically a rotating shaft). It provides position and vibration data essential for machine health

monitoring and protection.

Q2. What does “8 mm” refer to?

The “8 mm” designation refers to the diameter of the probe tip housing designed for the 3300 XL series. This size balances

 measurement robustness with mounting space requirements.

Q3. Why is this probe part of the 3300 XL series important?

The 3300 XL series is a modern, improved proximity transducer system offering enhanced interchangeability,

reliability, and environmental resistance compared to older 3300 series probes. Components (probe,

cable, and sensor) are designed to be interchangeable without bench recalibration,

simplifying maintenance and inventory.
