Introduction
The Bently Nevada 330173-00-04-10-02-00 is a compact 3300 5 mm proximity probe engineered for non-contact measurement of shaft position and dynamic movement in rotating machinery. It uses eddy-current sensing technology and is designed for integration with a compatible 3300 proximity transducer system.
This configuration combines an M8 × 1 mounting thread, 0.4-inch (approximately 10.2 mm) unthreaded length, 1.6-inch (approximately 40.6 mm) case length, and 1.0-meter cable. It also uses a miniature coaxial ClickLoc connector with standard cable and carries the standard configuration without additional agency approval.
Its relatively compact body makes the 330173-00-04-10-02-00 a practical solution for machinery locations where installation space is limited but dependable shaft monitoring remains essential. It is well suited to turbines, compressors, pumps, generators, motors, and other rotating assets where continuous vibration and shaft-position information can support predictive maintenance and machinery protection.

Applications
Turbine Shaft Vibration Monitoring
The probe can be installed in suitable turbine monitoring systems to detect dynamic shaft movement and changes in rotor position. Continuous proximity measurements can provide valuable input for machinery protection and maintenance programs.
Compressor Rotor Monitoring
Compressors operate under demanding mechanical conditions where rotor vibration and displacement can affect reliability. The 330173-00-04-10-02-00 provides a non-contact sensing point for compatible monitoring arrangements.
Pump and Motor Condition Monitoring
The compact probe body is useful for pumps and motors where available installation space is restricted. Shaft movement measurements can contribute to the detection of developing mechanical problems.
Generator Monitoring
For generators and other rotating electrical machinery, proximity measurements can be incorporated into a broader monitoring strategy to observe shaft behavior during operation.
Fluid-Film Bearing Applications
The 3300 5 mm platform is particularly suitable for machines using fluid-film bearings. Properly configured systems can monitor both static shaft position and dynamic vibration, providing a more complete picture of rotor behavior.
Space-Constrained Installations
The relatively short 1.6-inch case makes this configuration attractive for applications where a longer-bodied probe could interfere with surrounding components. Its metric M8 × 1 thread can also simplify integration into equipment using metric mounting standards.
Replacement and Maintenance Projects
For existing 3300 installations, using the exact 330173-00-04-10-02-00 configuration can help maintain the original mounting geometry and cable arrangement. This can make maintenance work more predictable and reduce unnecessary mechanical modifications.
Advantages
Compact 1.6-Inch Case
The 1.6-inch overall case length provides a good balance between installation reach and compactness. It is especially useful where the probe must fit into a relatively confined machinery location.
M8 × 1 Metric Mounting
The M8 × 1 thread makes this model a natural choice for equipment designed around metric mounting hardware. It should not, however, be considered a direct substitute for a 1/4-28 UNF probe without checking the complete installation.
Precise Non-Contact Sensing
Eddy-current technology allows the probe to monitor a conductive target without touching the rotating shaft. This eliminates sensing-tip contact and supports continuous operation on high-speed equipment.
Proven 5 mm Platform
The compact 5.2 mm sensing tip makes it possible to install the probe in locations where larger sensing arrangements may be difficult to accommodate.
Practical 1-Meter Cable
The 1.0-meter cable provides useful routing flexibility for common machinery installations while keeping cable management relatively straightforward.
Durable Stainless-Steel Housing
The AISI 304 stainless-steel case provides a robust mechanical enclosure suitable for industrial environments. The PPS probe tip is designed to withstand the operating conditions associated with the 3300 5 mm system.
ClickLoc Connector
The miniature coaxial ClickLoc connector provides a compact interface for compatible extension-cable and Proximitor arrangements, helping simplify installation and maintenance.
Strong Replacement Value
For facilities already operating 3300 5 mm monitoring systems, the exact mechanical configuration of this model can be valuable when replacing an installed probe without redesigning the mounting arrangement.
Technical FAQs
1. What is the Bently Nevada 330173-00-04-10-02-00?
It is a 3300 5 mm proximity probe featuring an M8 × 1 thread, 0.4-inch unthreaded length, 1.6-inch case length, 1.0-meter cable, miniature coaxial ClickLoc connector, and standard approval configuration.
2. What does the 330173 series represent?
The 330173 series identifies the M8 × 1 threaded, unarmored 3300 5 mm proximity probe configuration.
3. What does “00” indicate after 330173?
The first 00 identifies the applicable unthreaded-length configuration. For this model, the probe has a 0.4-inch (10.2 mm) unthreaded section as specified by the complete ordering configuration.
4. What does “04” represent?
The 04 identifies the 0.4-inch unthreaded / dimensional configuration associated with this probe ordering code. The corresponding overall case length is approximately 1.6 inches (40.6 mm).
5. How long is the cable?
The model uses a 1.0-meter (3.3-foot) total cable length.
6. What connector does the probe use?
The 02 connector option specifies a miniature coaxial ClickLoc connector with standard cable.
7. What thread does the probe have?
The probe uses an M8 × 1 metric thread. This is a key selection point when comparing it with 330171 or 330172 probes, which use 1/4-28 UNF threads.
8. What is the operating temperature range?
The 3300 5 mm probe is designed for a probe temperature range of approximately -35°C to +177°C (-31°F to +351°F).
9. How much does the probe weigh?
The typical probe weight is approximately 323 g (0.323 kg / 11.39 oz). The weight of a complete transducer system will be higher because it includes the extension cable and Proximitor sensor.
10. Can this probe replace another 3300 5 mm probe?
Only when the complete mechanical and electrical configuration is compatible. Particular attention should be given to the M8 × 1 thread, 0.4-inch unthreaded section, 1.6-inch case length, cable length, connector configuration, and approval requirements. Matching only the 5 mm probe diameter is not sufficient for a reliable replacement decision.
