Product Overview
When a turbine or compressor train goes down, every hour of downtime erodes margin. The Bently Nevada 146055-10-02-05 is a 3300 Series ceramic capped reverse mount probe built to keep radial vibration and position measurements trustworthy in exactly those high-stakes machines. It ships new and original in factory packing, so your maintenance team installs a known-good component rather than gambling on a refurbished unit.
This is a reverse mount design with a 3/8-24 UNF case thread, a 1.0 meter total length, and a Miniature ClickLoc coaxial connector on standard cable. The ceramic cap protects the sensing face in harsh service, which matters when a probe sits close to a bearing housing for years.

What the Numbers Mean on the Floor
The 3/8-24 UNF thread is a common mounting size, so the 146055-10-02-05 drops into existing tapped holes without adapters. The 1.0 m length suits short cable runs to a junction box, reducing the chance of a damaged extension. The alumina ceramic tip resists wear and electrical noise, while the AISI 304 stainless case handles corrosive plant atmospheres. The -51°C to +177°C range covers most steam and gas turbine environments, and the 34 Bar pressure seal supports installations where process gas is present.
Applications
Steam Turbine Radial Vibration
A 1.0 m probe with a Miniature ClickLoc connector is a practical fit for steam turbine bearing housings where the Proximitor Sensor sits nearby. The ceramic cap tolerates the heat and the reverse mount geometry keeps the cable exit clear of the bearing cap.
Compressor Position Monitoring
On centrifugal compressors, axial position measurement demands stable scale factor. The 146055-10-02-05 pairs with a 3300 5 mm system to deliver the linear range and incremental scale factor your protection system expects.
Replacement and Upgrade
If you are replacing a damaged 3300 probe, matching the exact part number avoids re-calibration surprises. The 146055-10-02-05 keeps your loop consistent with existing 3300 XL components.
Installation and Setup
Reverse mount probes install from the back of the housing, so verify thread engagement before final torque. The maximum thread engagement is 0.563 in. Keep the ceramic tip clean and free of metallic debris. Route the standard cable away from high-current conductors to protect signal integrity. For pressure-seal applications, confirm the 34 Bar rating matches your process before commissioning.
Compatibility and Integration
The 146055-10-02-05 works within a 3300 5 mm system that includes a Proximitor Sensor and extension cable. Performance characteristics apply to systems made solely of 3300 XL components. If you are wiring into a plant network, confirm cable and gateway requirements with your supplier.
Selection Checklist
Before ordering, confirm the thread size, total length, and connector type match your machine. Check that your Proximitor Sensor and extension cable are compatible 3300 components. Oil AutoTech offers hands-on technical selection help and fast dispatch, worldwide, so you get the right probe the first time.
