Introduction
The Bently Nevada 330173-00-04-10-02-00 is a 3300 5 mm proximity probe designed for non-contact measurement of shaft displacement, vibration, and position on rotating machinery. Its compact 5 mm sensing configuration makes it a practical solution for machinery-monitoring points where installation space is limited and a smaller probe diameter is preferred.
This configuration features a 3/8-24 UNF mounting thread, a 40 mil nominal case length, 1.0 m integral cable, and a miniature coaxial ClickLoc connector with standard cable. The final 00 option represents the standard configuration without an additional agency-approval requirement.
The 3300 5 mm proximity system is built around eddy-current sensing technology, allowing the probe to measure the relative movement between the probe tip and a conductive machine target without physical contact. This makes it well suited to vibration and position measurements on turbines, compressors, pumps, motors, generators, and other rotating assets.
For replacement applications, matching the complete part number is important. The probe diameter, mounting thread, case length, cable length, connector configuration, and approval option should all correspond to the existing installation.

Applications
Rotating Shaft Vibration
The 3300 5 mm proximity probe provides non-contact shaft-displacement measurement for vibration-monitoring applications. It can be installed around a suitable conductive shaft target to monitor radial movement during operation.
Radial Position Monitoring
The probe can provide continuous information about the relative position of a rotating shaft. This can be useful when machinery operating conditions require close observation of rotor movement.
Axial Position
In compatible applications, the 5 mm probe can be used to monitor axial shaft movement where the available installation space favors a smaller sensing arrangement.
Turbomachinery
The probe can be incorporated into monitoring arrangements for turbines and other rotating equipment where compact sensor dimensions are beneficial.
Pumps and Motors
Industrial pumps and motors can use proximity measurement to monitor shaft behavior without requiring physical contact between the probe and rotating component.
Compressors
The 3300 5 mm proximity system can be applied to selected compressor monitoring points where the machine geometry and required measurement range are compatible with the sensor system.
Compact Machinery Installations
The smaller probe diameter is particularly advantageous when access around the shaft is restricted or when the available mounting space is limited.
Advantages
Compact 5 mm Design
The 5 mm sensing configuration offers a smaller physical footprint than larger proximity probe families. This makes it attractive for machinery where installation access is constrained.
Non-Contact Measurement
Eddy-current sensing allows the probe to measure shaft movement without mechanical contact. This eliminates direct sensor-to-shaft wear and supports continuous measurement during machine operation.
1 m Integral Cable
The 1.0 m cable is a practical choice for installations with short distances between the sensing point and Proximitor Sensor. It helps keep cable routing neat and efficient.
3/8-24 UNF Thread
The 3/8-24 UNF mounting thread provides a clearly defined imperial mounting configuration suitable for compatible 3300 installations.
ClickLoc Connection
The miniature coaxial ClickLoc connector provides a secure connection arrangement for industrial vibration-monitoring environments.
Established 3300 System
The probe is designed for use within the Bently Nevada 3300 proximity transducer architecture. Correctly matching the probe with the appropriate Proximitor Sensor and system components helps maintain reliable signal characteristics.
Practical Replacement Solution
For maintenance teams replacing an existing 3300 5 mm probe, the detailed configuration of this model provides a straightforward reference point. Matching the original part number can reduce the risk of selecting a probe with the wrong thread, cable length, or connector arrangement.
Technical FAQs
1. What is the Bently Nevada 330173-00-04-10-02-00?
It is a Bently Nevada 3300 5 mm proximity probe configured with a 3/8-24 UNF mounting thread, 40 mil case dimension, 1 m cable, ClickLoc connector, and standard approval configuration.
2. What type of sensor is the 330173?
The 330173 is a non-contact eddy-current proximity probe used for measuring shaft displacement, vibration, and position.
3. Is the 330173 a 5 mm probe?
Yes. The 330173 belongs to the 3300 5 mm proximity probe family.
4. What mounting thread does this probe use?
This configuration uses a 3/8-24 UNF mounting thread.
5. How long is the integral cable?
The 10 cable option specifies a nominal 1.0 m (3.3 ft) integral cable.
6. What connector does the 02 option use?
The 02 option identifies the miniature coaxial ClickLoc connector with standard cable.
7. What does the final 00 indicate?
The final 00 identifies the standard configuration with no additional agency approval option.
8. Where can the 3300 5 mm proximity probe be used?
Typical applications include radial shaft vibration, radial position, axial position, turbines, compressors, pumps, motors, generators, and other rotating machinery, provided the target geometry and complete transducer-system requirements are suitable.
9. Can this probe replace a larger 8 mm or 11 mm proximity probe?
It should not be considered a direct replacement simply because all three technologies measure shaft displacement. The probe size, mounting geometry, linear range, Proximitor Sensor, cable configuration, and system calibration must be compatible.
10. What should be checked before ordering a replacement?
Confirm the 330173 model, 5 mm probe size, 3/8-24 UNF thread, case dimension, 1 m cable, ClickLoc connector, approval option, target geometry, probe gap, and compatibility with the installed 3300 Proximitor Sensor.
