Introduction
The Bently Nevada 330174-00-06-10-02-CN is a 3300 5mm Proximity Probe designed for non-contact measurement of shaft position and dynamic movement in rotating machinery. Unlike the 330173 family, the 330174 series uses an M8 × 1 thread with armored construction, making this configuration a useful choice where additional mechanical protection around the probe cable is required.
This model combines a 0 mm unthreaded section, 60 mm overall case length, 1.0 m total cable, miniature coaxial ClickLoc connector with standard cable, and CN country-specific approval configuration. The compact 60 mm case makes it particularly practical for installations where probe mounting space is limited.
The 3300 5mm transducer system is intended to work as a complete measurement chain with a compatible extension cable and Proximitor sensor. When correctly configured, the system can measure both static shaft position and dynamic vibration and can also support Keyphasor and speed-measurement applications.
Technical Specifications

Applications
Turbine Shaft Monitoring
The probe can be incorporated into compatible turbine monitoring systems to measure shaft displacement and dynamic movement. Its armored construction provides an additional layer of protection for installations where the probe lead may be exposed to mechanical contact.
Compressor Monitoring
In compressor applications, non-contact proximity measurement can provide information about rotor position and vibration. The compact 60 mm case can be advantageous where installation depth is restricted.
Generator Applications
Generators and other large rotating machines can use proximity probes as part of shaft-position and vibration-monitoring arrangements. The armored configuration is particularly attractive where cable protection is an installation priority.
Motor and Pump Monitoring
Compatible motors and pumps can use the 3300 5mm system for continuous non-contact shaft measurement. The M8 × 1 mounting thread makes the probe suitable for metric installations.
Fluid-Film Bearing Machinery
The 3300 5mm transducer system is widely suited to applications involving fluid-film bearings, where shaft position and vibration measurements are important. The complete system can provide both static and dynamic measurement information.
Machinery Protection
When connected to a compatible Proximitor sensor and monitoring system, the probe can contribute to machinery protection schemes that monitor abnormal shaft movement and vibration.
Space-Constrained Installations
The 60 mm overall case length and 0 mm unthreaded configuration are well suited to mounting arrangements where a longer probe body could interfere with surrounding machine components.
Harsh Mechanical Environments
The armored 330174 construction is a strong choice where the probe cable requires additional physical protection. It can help reduce the risk of cable damage caused by accidental contact, vibration, or nearby mechanical components.
Advantages
Armored Construction
The key distinction of the 330174 family is its armored design. Compared with the unarmored 330173 family, the additional armor provides greater mechanical protection around the probe cable.
Compact 60 mm Case
At only 60 mm overall case length, this model is well suited to installations with limited mounting space. It provides a useful balance between compact dimensions and the established 3300 5mm measurement platform.
M8 × 1 Metric Thread
The M8 × 1 mounting thread provides a compact metric interface and makes the probe suitable for compatible metric mounting arrangements.
Zero Unthreaded Length
The 00 configuration specifies 0 mm unthreaded length, which can simplify installations where the probe needs to seat directly against the mounting arrangement without an extended unthreaded section.
5.2 mm Sensing Tip
The compact 5.2 mm probe tip allows non-contact measurement in areas where larger sensing elements may be difficult to install.
Eddy-Current Measurement
The probe operates on the eddy-current principle, measuring the distance between the probe tip and a conductive target without physical contact. This makes it appropriate for continuously rotating shafts.
1.0 m Cable
The 1.0 m cable offers a practical cable length for many industrial installations and provides sufficient routing flexibility without introducing excessive cable.
ClickLoc Connector
The miniature coaxial ClickLoc connector provides a compact interface for compatible 3300 system components.
Industrial Temperature Capability
The 3300 5mm probe specifications support an operating temperature range of approximately -35°C to +177°C, making the platform suitable for a broad range of industrial machinery environments.
Country-Specific Approval
The CN suffix identifies a country-specific agency approval option. This makes the complete ordering code especially important when the probe is being purchased for an installation with defined certification requirements.
Technical FAQs
1. What is the Bently Nevada 330174-00-06-10-02-CN?
It is a 3300 5mm armored proximity probe featuring an M8 × 1 thread, 0 mm unthreaded length, 60 mm overall case, 1.0 m cable, miniature coaxial ClickLoc connector, and CN approval configuration.
2. What does 330174 identify?
The 330174 base designation identifies the 3300 5mm probe with M8 × 1 thread and armor. The related 330173 family uses the same metric thread but without armor.
3. What does the first “00” mean?
The first 00 specifies a 0 mm unthreaded length.
4. What does “06” specify?
The 06 identifies the 60 mm overall case-length option, approximately 2.36 inches.
5. How long is the cable?
The 10 cable option specifies a 1.0 m (3.3 ft) total cable length.
6. What does the “02” connector code mean?
The 02 option specifies a miniature coaxial ClickLoc connector with standard cable.
7. Is this probe armored?
Yes. 330174 is the armored M8 × 1 configuration. This is the primary construction difference between 330174 and 330173 probes.
8. What is the approximate probe weight?
The typical published weight is approximately 323 g (0.323 kg).
9. What is the maximum M8 × 1 thread engagement?
The specified maximum thread engagement for the M8 × 1 probe configuration is 12 mm. This should be considered when checking the installation hole and mounting arrangement.
10. Can a 330173-00-06-10-02-CN replace this probe?
Not automatically. Both models can share the M8 × 1 thread, 60 mm case, 1.0 m cable, and ClickLoc connector, but the 330174 version is armored, while 330173 is without armor. If cable protection is part of the original installation requirement, the armored configuration should be retained.
