Introduction
The Bently Nevada 330173-00-08-10-02-00 is a 3300 5 mm Proximity Probe configured for non-contact measurement of shaft position and dynamic movement in rotating machinery. It belongs to the 330173 family, which uses an M8 × 1 metric thread and a without-armor construction. When paired with the appropriate extension cable and Proximitor sensor, the 3300 5 mm transducer system can provide both static position and dynamic vibration measurements.
This specific configuration combines a 0 mm unthreaded section, 80 mm overall case length, 1.0 m total cable length, miniature coaxial ClickLoc connector with standard cable, and the 00 agency-approval option.
For maintenance teams replacing an existing probe, the complete part number is important. The 80 mm case and 1.0 m cable distinguish this version from other 330173 configurations, making it a practical choice when the original installation requires this particular mechanical and cable arrangement.
Technical Specifications
The 330173 ordering structure provides a straightforward way to identify the configuration. 330173 specifies the 3300 5 mm M8 × 1 probe without armor, while the remaining codes define the unthreaded length, case length, cable length, connector, and approval option.

Applications
Turbine Rotor Monitoring
The probe can be incorporated into suitable turbine monitoring systems for observing shaft displacement and rotor behavior. Continuous proximity measurements provide useful information for machinery protection and maintenance planning.
Compressor Monitoring
High-speed compressors can experience changes in shaft position and vibration as operating conditions or mechanical conditions develop. The 3300 5 mm system provides non-contact measurement for compatible compressor applications.
Pump and Motor Monitoring
The compact sensing tip and metric mounting arrangement make the probe suitable for compatible pumps, motors, and other rotating machinery where continuous shaft measurement is required.
Generator Applications
Generators and other critical rotating assets can use proximity probes as part of a larger vibration and shaft-position monitoring architecture.
Fluid-Film Bearing Machines
The 3300 5 mm transducer system is designed for applications involving fluid-film bearing machinery, where both static shaft position and dynamic vibration information can be important.
Keyphasor and Speed Measurement
Compatible 3300 5 mm system configurations can also be used for Keyphasor and rotational-speed measurements, allowing the same proximity-sensing platform to support several machinery-monitoring functions.
Replacement Installations
The 80 mm case + 1.0 m cable configuration is useful when an existing machine installation has a defined probe mounting depth and cable-routing requirement. Selecting the exact part number helps reduce the risk of replacing a correctly functioning mechanical arrangement with an incompatible probe geometry.
Advantages
80 mm Probe Case
The 80 mm case length provides a longer probe-body configuration than the shorter 20 mm, 40 mm, 50 mm, 60 mm, and 70 mm versions in the 330173 family. This can be valuable where the mounting arrangement requires additional probe length.
M8 × 1 Metric Thread
The M8 × 1 thread provides a compact metric mounting solution. It also differentiates this model from 330171 and 330172 probes, which use 1/4-28 UNF threads.
Compact 5 mm Sensing Tip
The probe uses a 5.2 mm tip, giving the 3300 5 mm system a compact sensing profile for installations where space around the measurement target is limited.
Non-Contact Measurement
Eddy-current technology allows the probe to measure the distance between the probe tip and a conductive target without physical contact. This is particularly valuable for rotating shafts because there is no sliding contact or mechanical probe-tip wear during normal measurement.
1.0-Meter Cable
The 1.0 m cable provides a practical balance between routing flexibility and cable management. It is longer than the 0.5 m configurations while remaining relatively compact for many machinery installations.
ClickLoc Connection
The miniature coaxial ClickLoc connector provides a compact connection method for compatible 3300 transducer-system components.
Stainless-Steel Construction
The probe case uses AISI 304 stainless steel, while the sensing tip uses PPS material. This combination provides a robust industrial construction suitable for demanding machinery-monitoring environments.
Exact Configuration for Maintenance
One of the strongest advantages of this model is configuration accuracy. The 80 mm case, 1.0 m cable, M8 × 1 thread, standard ClickLoc connector, and 00 approval option are all defined by the ordering number, making it easier for maintenance personnel to identify the intended replacement.
Technical FAQs
1. What is the Bently Nevada 330173-00-08-10-02-00?
It is a 3300 5 mm proximity probe featuring an M8 × 1 thread, without-armor construction, 80 mm case length, 1.0 m cable, miniature coaxial ClickLoc connector, and 00 agency-approval configuration.
2. What does the 330173 model number indicate?
330173 identifies a 3300 5 mm probe with an M8 × 1 thread and without armor. The related 330174 family uses the same metric thread but adds armor.
3. What does the first “00” mean?
The first 00 specifies a 0 mm unthreaded-length option.
4. What does “08” indicate?
The 08 specifies an 80 mm overall case length, approximately 3.15 inches.
5. How long is the cable?
The 10 configuration specifies a 1.0-meter (3.3-foot) total cable length.
6. What connector is fitted?
The 02 option specifies a miniature coaxial ClickLoc connector with standard cable.
7. Is this probe armored?
No. The 330173 family is the without-armor M8 × 1 version. For an armored M8 × 1 3300 5 mm probe, the 330174 family should be considered.
8. What is the sensing-tip diameter?
The 3300 5 mm probe has a 5.2 mm (0.21 in) probe tip diameter.
9. What is the probe weight?
The typical published component weight is approximately 0.323 kg (323 g). Shipping weight can be substantially higher because packaging and other shipping materials are included in those figures.
10. Can it directly replace any 3300 5 mm probe?
No. A replacement should be matched by the complete part number and installation requirements. Case length, unthreaded length, mounting thread, cable length, connector configuration, and approval option should all be checked before installation.
