FAQ

Q1 — What is a proximity transducer assembly?
A: It’s a sensor unit that uses eddy‑current technology to measure the gap between a fixed probe and a moving metal target (shaft). The assembly combines the probe and Proximitor sensor electronics in one housing, producing an analog signal used by machinery condition monitors.

Q2 — What does the part number represent?
A: In Bently Nevada nomenclature, the numbers encode options such as probe type (e.g., 8 mm 3300 XL), probe

penetration length (~35 mm), mounting thread style, and fittings included. Specific suffixes

(“‑28”, “‑035”, etc.) denote these configuration variants.

Q3 — Why choose an integrated PROXPAC XL assembly?
A: The integrated design removes the need for separate probes, extension cables, and Proximitor

housings, reducing installation labor, failure points, and wiring complexity,

while improving signal reliability.
