Introduction
The Bently Nevada 330173-00-05-10-12-00 is a 3300 5 mm proximity probe designed for non-contact measurement of shaft displacement, position, and dynamic vibration in rotating machinery. It belongs to the 330173 family, which uses an M8 × 1 mounting thread and unarmored construction.
This configuration combines a 50 mm overall case length, 1.0 m cable, and miniature coaxial ClickLoc connector with FluidLoc cable. The final 00 represents the standard agency-approval configuration. Product listings for this exact part number identify it as a 3300 5 mm probe with M8 × 1 thread, without armor, 1.0-meter cable, and FluidLoc cable construction.
The FluidLoc cable configuration is an important distinction from standard-cable versions. For maintenance teams working with established 3300 monitoring installations, the exact cable and connector configuration can be just as important as the probe diameter and mounting thread.
Technical Specifications
The 330173-00-05-10-12-00 is configured for installations requiring a metric M8 × 1 mounting arrangement and a relatively compact 50 mm probe body. Its complete part number should be used when specifying replacements because the suffixes define important mechanical and cable characteristics.

Applications
Turbine Shaft Monitoring
The 330173-00-05-10-12-00 can be incorporated into turbine monitoring arrangements where continuous measurement of shaft movement and position is required. Its non-contact sensing principle is well suited to high-speed rotating equipment.
Compressor Monitoring
Process and centrifugal compressors can benefit from proximity measurements that track changes in rotor behavior. The M8 × 1 mounting configuration provides a compact solution for compatible machinery installations.
Pump and Motor Applications
For pumps, motors, and other rotating equipment, shaft displacement and vibration measurements can contribute to machinery condition assessment and maintenance planning.
Generator Monitoring
The probe can be integrated into suitable generator monitoring systems to provide non-contact measurements of rotor movement and shaft position.
Fluid-Film Bearing Machinery
3300 5 mm proximity systems are well suited to machinery using fluid-film bearings. When paired with compatible system components, the probe can provide information on static shaft position and dynamic vibration.
Industrial Condition Monitoring
The probe can serve as part of a broader machinery-monitoring arrangement, helping maintenance teams observe changes in rotor behavior and identify developing mechanical issues.
Existing 3300 System Replacement
Because this is a specific 330173 configuration, it can be particularly valuable where an existing installation already calls for an M8 × 1 probe with a 1.0-meter FluidLoc cable and ClickLoc connector.
Advantages
FluidLoc Cable Construction
The 12 cable/connector configuration uses FluidLoc cable. This is the defining feature that separates this model from otherwise similar 330173 probes using standard cable. For replacement work, retaining the original cable construction can help preserve the intended installation configuration.
M8 × 1 Metric Thread
The M8 × 1 mounting thread makes the probe suitable for machinery and mounting arrangements designed around metric hardware. It also distinguishes the 330173 series from the 1/4-28 UNF threaded 330171 and 330172 families.
5 mm Non-Contact Measurement
The compact sensing format provides non-contact measurement of a conductive shaft target without physical contact between the probe tip and rotating surface.
Compact Installation Profile
The 330173 platform provides a relatively compact mechanical package for installations where available probe-mounting space is limited.
1-Meter Cable
The integrated 1.0-meter cable offers practical routing distance for many machinery installations while avoiding unnecessary cable length.
ClickLoc Connector
The miniature coaxial ClickLoc connector provides a compact connection arrangement suitable for compatible 3300 system components.
Standard Approval Configuration
The final 00 identifies the standard agency-approval option, making the complete ordering code straightforward to identify for standard installations.
Useful for Maintenance Standardization
For plants operating multiple 3300 5 mm installations, maintaining exact part-number matching can simplify inventory planning and reduce the risk of installing a probe with an incompatible thread, cable, or connector arrangement.
Technical FAQs
1. What is the Bently Nevada 330173-00-05-10-12-00?
It is a 3300 5 mm proximity probe featuring an M8 × 1 thread, unarmored construction, 50 mm case-length configuration, 1.0-meter cable, miniature coaxial ClickLoc connector, and FluidLoc cable.
2. What does the 330173 family represent?
The 330173 family identifies the M8 × 1 threaded, unarmored 3300 5 mm proximity probe configuration.
3. What does the first “00” indicate?
The first 00 represents the 0.0-inch unthreaded-length option in the ordering configuration.
4. What does “05” specify?
The 05 identifies the 5.0-inch overall case-length option in the probe configuration.
5. How long is the cable?
The model uses a 1.0-meter (3.3-foot) cable.
6. What is special about the “12” configuration?
The 12 option identifies a miniature coaxial ClickLoc connector with FluidLoc cable. This is one of the most important differences between this model and related 330173 probes with standard cable.
7. Does the probe have cable armor?
No. The 330173 family is the without-armor configuration. The 330174 family is the corresponding armored M8 × 1 family.
8. What mounting thread does it use?
The probe uses an M8 × 1 metric thread. It should therefore be selected based on the actual machinery mounting arrangement rather than simply by matching the 5 mm sensing size.
9. What is the approximate probe weight?
The typical 3300 5 mm probe weight is approximately 323 g (0.323 kg / 11.4 oz). Complete system weight will depend on the associated extension cable and Proximitor sensor.
10. Can this model replace a 330173 probe with a standard cable?
Not automatically. Even when the thread and probe dimensions are similar, the FluidLoc cable configuration should match the intended installation. The complete part number, cable construction, connector, probe dimensions, and approval requirements should be verified before replacement.
