Introduction
The Bently Nevada 330171-00-10-10-02-00 is a 3300 5 mm Proximity Probe designed for precise non-contact measurement of shaft position and vibration in rotating machinery. Built around a 1/4-28 UNF threaded probe body, this configuration features a compact 1.0-inch case, a 1.0-meter integral cable, and a miniature coaxial ClickLoc connector with standard cable construction.
This particular configuration is a practical choice for installations where a compact probe body and moderate cable reach are preferred. The probe is designed to operate as part of a complete 3300 5 mm proximity transducer system, working with the appropriate extension cable and Proximitor Sensor to convert minute changes in the distance between the probe tip and conductive machine target into a reliable electrical signal.
The 3300 5 mm design incorporates Bently Nevada technologies such as TipLoc probe-tip molding and ClickLoc connection technology. Its compact construction makes it suitable for a wide range of machinery-monitoring applications, including turbines, compressors, pumps, motors, and other rotating assets where dependable vibration and position measurement are essential.

Applications
Turbine Shaft Monitoring
The 330171-00-10-10-02-00 can be integrated into compatible 3300 5 mm proximity systems for monitoring shaft vibration and position on rotating turbine equipment. Its compact case is useful where available mounting space is limited.
Compressor Protection
In compressor applications, proximity probes are commonly installed around bearings and rotating shafts to detect changes in shaft position or vibration. The 1.0-meter integral cable offers a convenient connection length for installations where the monitoring electronics are located relatively close to the probe.
Pump Monitoring
Industrial pumps can experience shaft movement, mechanical looseness, imbalance, and other conditions that benefit from continuous proximity measurement. The 3300 5 mm platform provides a proven approach for monitoring these mechanical variables.
Motor and Generator Applications
The probe can be used in compatible systems for monitoring shaft behavior on motors and generators. Non-contact measurement allows the sensing element to observe shaft movement without physically contacting the rotating target.
Gearbox and Rotating Machinery
The compact probe configuration is suitable for machinery where installation access is restricted. Its 1/4-28 UNF threaded case allows it to be mounted in appropriately prepared machine housings.
Machinery Protection Systems
When integrated with the appropriate 3300 Proximitor Sensor and extension cable, the probe becomes part of a complete eddy-current proximity measurement chain used for machinery protection and condition monitoring.
Maintenance and Replacement Applications
For existing installations specified around a 330171 5 mm probe with 0.0-inch unthreaded length, 1.0-inch case length, 1.0-meter cable, 02 connector configuration, and 00 approval option, this model provides a precise replacement choice.
Advantages
Compact 5 mm Probe Design
The 5 mm sensing format provides a relatively small installation footprint while still delivering the non-contact measurement capability expected from a dedicated machinery proximity probe.
1/4-28 UNF Thread
The 1/4-28 UNF threaded body provides a standardized mechanical mounting interface for compatible machine installations. Proper thread engagement and installation torque remain important for reliable mechanical installation.
1.0-Meter Integral Cable
The integrated 1.0-meter cable provides a useful connection distance without requiring an immediately adjacent extension cable. This configuration is well suited to installations where the Proximitor Sensor or extension connection is within relatively short reach.
ClickLoc Connection Technology
The miniature coaxial ClickLoc connector provides a positive connection between the probe cable and compatible extension components. The locking-style connection helps maintain a secure signal path during operation.
TipLoc Probe Construction
The 3300 5 mm probe incorporates Bently Nevada's TipLoc molding approach, which is designed to create a robust bond between the probe tip and probe body. This supports the probe's durability in industrial machinery service.
Wide Temperature Capability
The standard 3300 5 mm probe documentation specifies a temperature range extending from -51°C to +177°C, providing substantial operating flexibility for many industrial machinery applications.
Defined Cable Bend Radius
The specified minimum cable bend radius of 25.4 mm provides a practical installation reference and helps prevent excessive mechanical stress on the integral cable.
Straightforward Configuration
The final 00 approval suffix means no additional agency approval is required, making this version a straightforward option for installations that do not require a special certification configuration.
Technical FAQs
1. What is the Bently Nevada 330171-00-10-10-02-00?
It is a 3300 5 mm Proximity Probe with a 1/4-28 UNF thread, 0.0-inch unthreaded length, 1.0-inch case length, 1.0-meter integral cable, standard miniature coaxial ClickLoc connector, and no additional agency approval.
2. What type of thread does this probe use?
The 330171 series is specified with a 1/4-28 UNF thread and is supplied without armor in this basic probe configuration.
3. What does the first “00” mean?
The first 00 identifies a 0.0-inch unthreaded length. The probe therefore uses the minimum unthreaded-length configuration.
4. What does the second “10” mean?
The second field, 10, identifies a 1.0-inch overall case length, equivalent to approximately 25.4 mm.
5. How long is the integral cable?
The third configuration field, 10, specifies a 1.0-meter (3.3-foot) total cable length.
6. What connector does the probe use?
The 02 option specifies a miniature coaxial ClickLoc connector with standard cable. It differs from the 01 configuration, which includes a connector protector.
7. Does the probe include armor?
No. The 330171 base configuration described for this model is a 1/4-28 UNF 3300 5 mm probe without armor.
8. What is the probe weight?
The published 3300 5 mm documentation gives a typical probe weight of approximately 323 g (11.39 oz).
9. What is the minimum cable bend radius?
The specified minimum cable bend radius is 25.4 mm (1.0 inch). Maintaining this radius during installation helps avoid excessive stress on the integral cable.
10. What is the difference between 330171-00-10-10-02-00 and 330171-00-10-10-02-05?
The core probe configuration is the same: 0.0-inch unthreaded length, 1.0-inch case, 1.0-meter cable, and 02 standard ClickLoc connector. The difference is the final approval suffix. 00 means agency approval is not required, while 05 identifies the multiple-approval configuration. The appropriate version should be selected according to the certification requirements of the installation.
