Introduction
The Bently Nevada 330173-00-02-10-02-05 is a 3300 5 mm proximity probe designed for precise, non-contact measurement of shaft position and dynamic movement in rotating machinery. It belongs to the 330173 configuration family, which uses an M8 × 1 mounting thread and an unarmored probe construction.
This particular model features a 0.2-inch case length, 1.0-meter cable, miniature coaxial ClickLoc connector, and multiple-approval configuration. Its compact mechanical profile makes it an attractive choice for installations where available mounting space is limited and a short probe configuration is required.
When integrated with the appropriate extension cable and Proximitor sensor, the 330173-00-02-10-02-05 can become part of a complete 3300 5 mm transducer system for monitoring shaft vibration, radial position, thrust position, and other critical rotating-equipment parameters.
Technical Specifications
The 330173 family is the M8 × 1 threaded version of the 3300 5 mm proximity probe. The complete part number should be retained when specifying a replacement because the individual suffixes define the probe's mechanical dimensions, cable length, connector arrangement, and approval configuration.

Applications
Turbine Shaft Monitoring
The 330173-00-02-10-02-05 can be incorporated into suitable turbine monitoring arrangements to detect changes in shaft position and dynamic rotor movement. Continuous measurements can support machinery protection and condition-monitoring programs.
Compressor Monitoring
Rotating compressors can experience changes in shaft position and vibration as operating conditions, bearing conditions, or alignment change. A properly installed proximity probe provides a non-contact measurement point for these parameters.
Pump and Motor Applications
The compact probe configuration can be useful for pumps, motors, and other rotating machines where mounting space is restricted. Its metric M8 × 1 thread can also simplify integration into machinery designed around metric mounting hardware.
Generator Monitoring
Generators and other critical rotating equipment can use proximity measurements as part of a broader vibration and shaft-position monitoring strategy.
Fluid-Film Bearing Systems
The 3300 5 mm transducer platform is particularly useful for machines equipped with fluid-film bearings. Properly configured systems can provide information about both static shaft position and dynamic vibration.
Compact Retrofit Installations
The very short case length is one of the strongest reasons to consider this configuration. Where an existing installation has limited clearance around the probe mounting point, a compact 330173 configuration can provide a practical replacement solution without requiring a larger sensor body.
Advantages
Extremely Compact Case
With a 0.2-inch case length, this configuration offers a very compact mechanical package. It is well suited to installations where conventional longer-body probes may interfere with surrounding machinery or mounting hardware.
M8 × 1 Metric Thread
The M8 × 1 thread provides an important advantage for machinery designed around metric mounting standards. It also distinguishes this model from the 1/4-28 UNF 330171/330172 families.
Proven Non-Contact Measurement
The eddy-current sensing principle allows the probe to measure a conductive shaft target without physical contact. This avoids mechanical wear at the sensing interface and makes the technology suitable for high-speed rotating equipment.
Compact 5 mm Sensing Tip
The approximately 5.2 mm sensing tip allows the probe to be installed in relatively confined measurement locations while maintaining the capabilities of the 3300 5 mm platform.
1-Meter Cable
The 1.0-meter cable provides practical routing flexibility for many machinery installations. It is long enough for common probe-to-extension arrangements without introducing unnecessary cable length.
Stainless-Steel Construction
The probe case uses AISI 303/304 stainless steel, while the sensing tip is manufactured from PPS. This provides a robust package for industrial machinery applications.
Multiple-Approval Configuration
The final 05 identifies the multiple-approval option. This can be useful when the installation requires a specific combination of equipment approvals.
Suitable for Replacement Programs
For facilities maintaining an established 3300 monitoring architecture, retaining the exact 330173-00-02-10-02-05 configuration can help preserve the original mechanical arrangement and minimize unnecessary installation changes.
Technical FAQs
1. What is the Bently Nevada 330173-00-02-10-02-05?
It is a Bently Nevada 3300 5 mm proximity probe with an M8 × 1 thread, compact 0.2-inch case, 1.0-meter cable, miniature coaxial ClickLoc connector, and multiple-approval configuration.
2. What does the 330173 base model indicate?
The 330173 family identifies a 3300 5 mm proximity probe using an M8 × 1 mounting thread and unarmored construction.
3. What does “00” indicate?
The 00 identifies the applicable probe-body configuration preceding the case-length specification. The complete part number should be used rather than interpreting an individual field in isolation.
4. What does “02” mean in the part number?
The 02 identifies the 0.2-inch case-length configuration, approximately 5.1 mm.
5. How long is the cable?
The model uses a 1.0-meter (3.3-foot) cable.
6. What connector does this probe use?
The 02 connector configuration uses a miniature coaxial ClickLoc connector with standard cable.
7. What thread does the probe use?
The 330173 family uses an M8 × 1 metric mounting thread. This is an important distinction when selecting a replacement for a 330171 or 330172 probe, which uses a 1/4-28 UNF thread.
8. What is the operating temperature range?
The 3300 5 mm probe family is designed for a probe temperature range of approximately -35°C to +177°C (-31°F to +351°F).
9. What is the probe weight?
The typical 3300 5 mm probe weight is approximately 323 g (11.39 oz). The complete transducer system will be heavier once the extension cable and Proximitor sensor are included.
10. Can the 330173-00-02-10-02-05 replace a 330171 probe?
Not automatically. Although both belong to the 3300 5 mm family, the 330173 uses an M8 × 1 thread, while the 330171 uses 1/4-28 UNF. The mounting thread, case length, sensing position, cable arrangement, connector, and approval configuration should all match the existing installation before replacement.
