330106-XX-XX-10-02-00 MOD:145628-01 Bently Nevada reversely mounted proximity probe

The 330106-XX-XX-10-02-00 MOD:145628-01 is part of the 3300 XL 8mm reverse-mount proximity probe range. In use, it’s mainly for non-contact measurement on rotating machinery. That includes radial vibration, axial position, shaft eccentricity, and also Keyphasor/speed signals when required.

You’ll see it mostly on critical rotating equipment where continuous monitoring is needed rather than occasional checks.

This MOD code is basically a reverse-mount design adjustment. Instead of standard external threading, the probe is configured to be installed from the inside or through a dedicated sleeve.

It’s used when there isn’t enough external access space. So in practice, it solves mechanical installation limitations rather than changing the sensing function itself.

The configuration breakdown is as follows:

• 330106: Identifies the 3300 XL 8mm reverse-mount probe body with M10 x 1 metric thread
• XX-XX: Placeholders for Unthreaded Length and Overall Case Length options (must match machine casing thickness)
• 10: Denotes integrated probe cable length of 1.0 meter (approx. 39 inches)
• 02: Specifies cable termination with Miniature ClickLoc coaxial connector
• 00: Confirms no fluid leakage resistance or fluid armoring options
• MOD:145628-01: Signals dedicated reverse-mount housing assembly

Most of the time it’s seen in power plants and oil & gas facilities. Steam turbines, gas turbines, compressors, large pumps, and heavy motors are the typical applications.

It’s basically a standard front-end sensor in API 670 machinery protection setups.

As a front-end sensor element, the Bently Nevada 330106-XX-XX-10-02-00 MOD:145628-01 requires additional components:

• 3300 XL extension cable (scaled to 5-meter or 9-meter total system length)
• 3300 XL Proximitor Sensor (such as the 330180 series)
• Bently Nevada 3500 Machinery Protection Rack module (typically 3500/40M Proximitor Monitor or 3500/42M Vibration Monitor card)
