Bently Nevada 330195-02-12-50-00 Reverse Mount Proximity Probe

Product Overview

The Bently Nevada 330195-02-12-05-00 is a 3300 XL 8 mm reverse mount proximity probe engineered for extreme industrial environments.
It delivers stable vibration and displacement measurements, even when machinery operates under elevated or fluctuating temperatures.
Moreover, this probe belongs to the proven 3300 XL Proximity Transducer System used across global rotating equipment fleets.
Engineers select this model when installation space is limited and long-term measurement reliability remains critical.

Functional Highlights

Firstly, the extended temperature range design supports reliable operation in harsh thermal and mechanical conditions.
In addition, the reverse mount configuration simplifies installation on machines with restricted external access.
Therefore, maintenance teams can achieve accurate shaft vibration measurements without complex mechanical modifications.
Moreover, the 8 mm probe tip ensures high sensitivity and repeatable signal performance across the full measurement range.
For instance, turbomachinery operators rely on this probe for continuous protection and early fault detection.
