Bently Nevada 330106-05-30-15-02-00 Reverse Mount Probe

Product Overview

The Bently Nevada 330106-05-30-15-02-00 is a 3300 XL 8 mm reverse mount proximity probe engineered for demanding industrial monitoring environments.
It delivers stable, repeatable displacement and vibration measurements for critical rotating machinery operating under harsh mechanical conditions.
Moreover, the reverse mount design simplifies installation where axial space limitations restrict the use of standard probe configurations.
As part of the proven 3300 XL platform, this probe integrates seamlessly into established machinery protection and condition monitoring systems.
Therefore, maintenance teams gain consistent signal performance without compromising installation flexibility or long-term reliability.

Key Features and Functional Benefits

This probe provides high measurement accuracy across a wide operating temperature range common in heavy industrial applications.
In addition, the PPS probe tip material resists chemical exposure, moisture ingress, and mechanical wear during continuous operation.
The 75 ohm coaxial cable with FEP jacket improves signal integrity while maintaining flexibility during routing and installation.
Moreover, reverse mounting allows safer installation from outside the machine casing, reducing maintenance time and exposure risk.
For instance, operators can replace probes without extensive disassembly of surrounding mechanical structures.
