Introduction
The Bently Nevada 330196-05-30-50-05 is a 3300 XL 8 mm Extended Temperature Range (ETR) Reverse Mount Probe configured with an M10 x 1 metric thread and a 5.0 m (16.4 ft) total probe length.
This model is intended for applications where a reverse-mounted proximity probe is required and the monitoring electronics are positioned some distance from the machinery. The 330196 family is the M10 x 1 metric-thread version of the 3300 XL 8 mm ETR reverse-mount design, while the corresponding 330195 family uses 3/8-24 UNF threading.
With its Extended Temperature Range construction, compact 8 mm sensing tip, metric mounting interface, and long 5-meter cable configuration, the 330196-05-30-50-05 is a practical choice for demanding turbine, compressor, generator, pump, and other critical rotating-machinery monitoring applications.
Technical Specifications
The ordering code is especially useful for identifying this configuration. 330196 designates the M10 x 1 reverse-mount family. 05 identifies the mounting configuration with a 50 mm overall case length, 30 identifies the 5.0 m total length, and the final 05 specifies the CSA, ATEX, and IECEx approval configuration. The 3300 XL documentation lists the 330196 family with M10 x 1 threads and case lengths ordered in 10 mm increments.

Applications
The 330196-05-30-50-05 is designed for non-contact monitoring of conductive targets on rotating machinery. Its reverse-mount arrangement is particularly useful when access to the front of the probe installation is restricted.
The 3300 XL system produces an output proportional to the distance between the probe tip and the observed conductive surface. This enables measurement of both static shaft position and dynamic shaft vibration. Keyphasor reference and speed measurement are also established applications for the 3300 XL 8 mm system.
Typical applications include:
-
Steam turbine shaft vibration monitoring
-
Gas turbine machinery protection
-
Compressor rotor monitoring
-
Generator shaft-position measurement
-
Centrifugal pump monitoring
-
Motor shaft monitoring
-
Fluid-film bearing monitoring
-
Radial shaft vibration measurement
-
Axial shaft-position measurement
-
Keyphasor reference applications
-
Rotational speed measurement
-
Critical rotating-equipment protection
-
Industrial condition-monitoring systems
The 5-meter length provides additional freedom when the Proximitor Sensor or instrumentation cabinet is located away from the machine.
For a professional installation, the probe, extension cable, and Proximitor Sensor should be treated as a complete transducer system, with particular attention paid to the required total electrical length.
Advantages
Metric Reverse-Mount Configuration
The M10 x 1 thread gives this model a clear advantage for machinery using metric mounting hardware. The reverse-mount arrangement is also valuable where conventional front installation is obstructed.
50 mm Case Length
The 50 mm case provides a compact mechanical configuration while still offering sufficient body length for many restricted-access mounting arrangements. It sits toward the shorter end of the available metric case-length range.
5-Meter System Length
The 5.0 m total length is the standout feature for remote instrumentation applications. It can provide substantially more installation freedom than shorter 0.5 m, 1 m, 1.5 m, or 2 m versions.
The 3300 XL documentation specifically notes that 5-meter probes are designed for use with the 5-meter Proximitor Sensor.
Extended Temperature Range
The ETR construction is intended for applications where the probe cable and sensing assembly must operate in elevated-temperature machinery environments.
This makes the configuration particularly attractive for demanding applications involving turbines, compressors, and other high-energy rotating equipment.
8 mm Non-Contact Sensing
The 8 mm probe tip provides non-contact measurement of conductive targets. The system can therefore monitor shaft movement without physical contact between the probe and rotating component.
Multiple International Approvals
The final -05 identifies the CSA, ATEX, and IECEx approval configuration, providing useful flexibility for industrial installations where recognized international or hazardous-area approvals are required.
Compact Cable Routing
The approximately 2.54 mm cable diameter helps keep routing manageable despite the 5-meter overall length. The cable should nevertheless be routed with appropriate support and bend-radius control.
Practical Replacement Choice
For maintenance applications requiring an M10 x 1 reverse-mount probe with a 50 mm case and 5-meter system length, the 330196-05-30-50-05 provides a highly specific configuration that can simplify replacement selection.
Technical FAQs
1. What is the Bently Nevada 330196-05-30-50-05?
It is a 3300 XL 8 mm Extended Temperature Range Reverse Mount Proximity Probe featuring an M10 x 1 metric thread, 50 mm case length, 5.0 m total length, and CSA, ATEX, and IECEx approvals.
2. What thread does this probe use?
The probe uses an M10 x 1 metric thread. The 330195 reverse-mount family provides the corresponding 3/8-24 UNF configuration.
3. What does the first “05” mean?
In the 330196-05-30-50-05 ordering format, the first 05 identifies the 50 mm overall case-length configuration.
4. What does “30” represent?
The 30 identifies the 5.0 m total probe length in this particular ordering configuration.
5. What does the final “05” mean?
The final 05 represents the multiple-approval option, including CSA, ATEX, and IECEx approvals.
6. Is the 330196-05-30-50-05 a reverse-mount probe?
Yes. The 330196 family is specifically designated for 3300 XL 8 mm ETR reverse-mount probes with M10 x 1 threads.
7. What is the probe-tip diameter?
The sensing tip has a nominal diameter of 8.0 mm (0.31 in).
8. How long is the cable?
The nominal total probe length is 5.0 m (16.4 ft). The 3300 XL ordering documentation provides 5-meter and 9-meter configurations in addition to shorter lengths.
9. Can a 5-meter probe be used with any 3300 XL Proximitor Sensor?
The 3300 XL documentation specifically states that 5-meter probes are designed for use with the 5-meter Proximitor Sensor. Therefore, the complete system configuration should be verified before installation or replacement.
10. What should be checked before ordering a replacement?
Verify the M10 x 1 thread, reverse-mount arrangement, 50 mm case length, 5.0 m total length, ETR construction, approval option, connector configuration, cable routing requirements, and compatible 5-meter Proximitor Sensor. The 8 mm sensing-tip diameter alone does not establish interchangeability.
