Bently Nevada 330101-00-12-10-02-00 3300 XL 8 mm Proximity Probes

The Bently Nevada 330101-00-12-10-02-00 is part of the 3300 XL 8 mm Proximity Transducer System, a trusted and field-proven solution used extensively for machinery condition monitoring and protection. This particular model is a proximity probe designed to measure the distance between the probe tip and the observed surface, typically a rotating shaft. The system operates based on eddy current technology, delivering reliable non-contact measurement of shaft position and vibration in industrial rotating machinery.

The 3300 XL series offers robust construction, improved immunity to electrical noise, and extended durability in harsh industrial environments. The probe is compatible with other 3300 XL series components such as extension cables and Proximitor® sensors, and is typically used with monitoring systems for critical equipment such as turbines, compressors, pumps, and motors.

This specific part number — 330101-00-12-10-02-00 — denotes a standard unarmored 8 mm probe with 12 ft cable length, a 10 ft extension cable, and a 3300 XL Proximitor sensor calibrated to a -24 Vdc power supply.
