Bently Nevada 330907-05-30-10-02-00 Reverse Mount Proximity Probe

Product Summary

The Bently Nevada 330907-05-30-10-02-00 reverse mount proximity probe assembly delivers precise vibration and displacement measurement for critical rotating machinery.
It belongs to the proven 3300 XL series, trusted globally for turbomachinery protection, reliability, and long-term measurement stability.
Moreover, the reverse mount configuration supports installations where axial space or probe accessibility remains severely limited.
This factory-sealed, new assembly ships from the United States with a standard twelve-month manufacturer warranty.

Functional Highlights

The reverse mount probe design simplifies installation within tight bearing housings and compact machine casings.
In addition, the 8 mm sensing tip provides high-resolution displacement data for demanding vibration monitoring applications.
The robust stainless-steel probe body withstands harsh industrial environments, including oil mist and continuous mechanical stress.
Therefore, maintenance teams gain reliable early fault detection while minimizing unplanned machinery downtime.
Moreover, the low-noise coaxial cable improves signal integrity across long cable runs in electrically noisy environments.
