Introduction
The Bently Nevada 330173-00-05-10-01-00 is a 3300 5 mm proximity probe intended for non-contact measurement of shaft position and dynamic movement on rotating machinery. It belongs to the 330173 configuration family, using an M8 × 1 metric mounting thread and an unarmored probe construction.
This particular configuration combines a 0.0 mm unthreaded-length option, 50 mm overall case length, 1.0 m cable, and miniature coaxial ClickLoc connector with connector protector. The final 00 identifies the standard agency-approval configuration. Product listings for the exact part number also identify it as a 3300 5 mm proximity sensor/transducer.
With its compact 5 mm sensing format and metric mounting arrangement, the 330173-00-05-10-01-00 is a practical choice for rotating-equipment monitoring where installation geometry, cable routing, and replacement compatibility all matter.
Technical Specifications
The 330173 series is designed around the M8 × 1 threaded 3300 5 mm probe configuration. For replacement work, the complete part number is important because the individual code sections determine the mechanical dimensions, cable length, connector configuration, and approval option.

Applications
Turbine Rotor Monitoring
The probe can be incorporated into suitable turbine monitoring arrangements to measure shaft movement and position. These measurements can help operators identify abnormal rotor behavior and support machinery protection strategies.
Compressor Shaft Measurement
In compressors, continuous proximity measurement can help monitor radial or axial shaft movement. The compact M8 × 1 mounting arrangement is useful for machinery installations designed around metric hardware.
Pump Condition Monitoring
Pumps can experience imbalance, bearing degradation, alignment problems, and other mechanical conditions that influence shaft movement. A properly configured proximity system can provide valuable operating data for condition-based maintenance.
Generator Applications
The probe can be used as part of a generator shaft monitoring arrangement, providing non-contact measurements that can contribute to continuous observation of rotor behavior.
Fluid-Film Bearing Machinery
The 3300 5 mm platform is well suited to rotating machinery using fluid-film bearings. When combined with the appropriate monitoring electronics, it can provide information on both static shaft position and dynamic vibration.
Industrial Rotating Equipment
The compact probe format makes the 330173-00-05-10-01-00 suitable for a range of industrial rotating assets, particularly installations where a metric mounting thread and defined probe-body geometry are required.
Maintenance and Replacement Projects
For plants already using 3300 5 mm monitoring equipment, retaining the same probe configuration can help reduce installation modifications and simplify spare-parts management.
Advantages
50 mm Compact Probe Body
The 50 mm case length offers a useful balance between compact installation and mechanical reach. It can fit machinery locations where longer probe configurations may be inconvenient.
M8 × 1 Metric Thread
The M8 × 1 mounting thread makes the 330173 family suitable for metric machinery arrangements. This is a major selection difference from 330171 and 330172 models using 1/4-28 UNF threads.
Non-Contact Eddy-Current Sensing
The probe measures the position of a conductive target without physically contacting the rotating shaft. This eliminates mechanical wear at the sensing interface and supports continuous operation.
5 mm Sensing Format
The small probe tip allows installation in relatively confined measurement locations while maintaining the capabilities of the 3300 5 mm transducer platform.
Protected ClickLoc Connector
The 01 configuration includes a connector protector along with the miniature coaxial ClickLoc connector. This can provide a more secure and protected connection arrangement in industrial installations.
Practical 1-Meter Cable
The 1.0 m cable is suitable for many common probe installations and can keep cable routing relatively straightforward when the associated monitoring hardware is positioned nearby.
Established Monitoring Platform
The 3300 5 mm family is designed to work as part of a complete proximity transducer system. This allows the probe to be integrated into established machinery monitoring architectures rather than functioning as an isolated sensor.
Strong Spare-Part Candidate
For maintenance teams supporting existing Bently Nevada 3300 installations, an exact part-number match can be valuable because it preserves important mechanical characteristics that may otherwise be overlooked during replacement.
Technical FAQs
1. What is the Bently Nevada 330173-00-05-10-01-00?
It is a 3300 5 mm proximity probe with an M8 × 1 mounting thread, 50 mm case length, 1.0 m cable, miniature coaxial ClickLoc connector with connector protector, and standard approval configuration.
2. What does the 330173 series represent?
The 330173 series identifies the M8 × 1 threaded, unarmored 3300 5 mm proximity probe family.
3. What does the first “00” indicate?
The first 00 identifies the 0.0 mm unthreaded-length option in the ordering configuration.
4. What does “05” specify?
The 05 identifies the 50 mm overall case-length option, approximately 1.97 inches.
5. How long is the cable?
This model uses a 1.0-meter (3.3-foot) cable.
6. What connector is used?
The 01 option specifies a miniature coaxial ClickLoc connector with connector protector and standard cable.
7. What mounting thread does the probe use?
The 330173 family uses an M8 × 1 metric mounting thread. It should therefore not be assumed to directly replace a 330171 or 330172 probe without checking the existing mounting arrangement.
8. What is the approximate probe weight?
The typical probe weight is approximately 323 g (0.323 kg / 11.4 oz). A complete transducer system will be heavier once the extension cable and Proximitor sensor are included.
9. What measurements can this probe support?
When installed as part of a compatible 3300 5 mm transducer system, the probe can support non-contact shaft-position and dynamic vibration measurement. Depending on the overall system configuration, the platform can also support suitable speed and Keyphasor-related applications.
10. Can the 330173-00-05-10-01-00 replace another 3300 5 mm probe?
Only after checking the complete configuration. The mounting thread, case length, unthreaded section, cable length, connector style, and approval configuration should all correspond to the intended installation. A matching 5 mm tip alone does not guarantee interchangeability.
