Introduction
The Bently Nevada 330193-00-02-50-00 is a 3300 XL 8 mm Extended Temperature Range (ETR) Proximity Probe configured with an M10 x 1 metric thread, a 20 mm overall case length, and a 5.0 m (16.4 ft) integral cable. As a standard, non-armored probe, it provides a compact metric mounting solution for machinery monitoring applications where additional cable armor is not required.
The 330193 family is designed for use in 3300 XL 8 mm proximity transducer systems. The probe provides non-contact sensing of conductive machinery targets and can be used for monitoring shaft vibration, radial position, axial position, and other dynamic characteristics when paired with the appropriate Proximitor Sensor.
The 5-meter configuration is particularly useful for installations requiring a longer integrated probe cable while keeping the installation straightforward. It is also important to note that 5-meter probes are specifically designed for use with a 5-meter Proximitor Sensor, so system-length matching is an essential part of proper selection.
Technical Specifications
The 330193-00-02-50-00 ordering code identifies a specific metric probe configuration. The 330193 family represents the M10 x 1, non-armored 3300 XL 8 mm ETR probe; 00 specifies the minimum unthreaded length, 02 identifies the 20 mm case length, 50 specifies the 5.0 m total length, and the final 00 indicates that no agency approval option is required.

Applications
The 330193-00-02-50-00 is intended for non-contact monitoring of rotating machinery as part of a compatible 3300 XL 8 mm proximity transducer system.
Its 5-meter integral cable makes it suitable for installations where the proximity probe must be positioned at the machine while the Proximitor Sensor is located farther away in an instrumentation cabinet or protected control area.
Typical applications include:
- Steam turbine shaft vibration monitoring
- Gas turbine machinery protection
- Compressor shaft monitoring
- Generator rotor monitoring
- Pump and motor vibration measurement
- Radial shaft-position monitoring
- Axial-position monitoring
- Bearing and rotor condition monitoring
- Critical rotating machinery protection
- Industrial machinery condition monitoring
The metric M10 x 1 mounting thread is useful for equipment designed around metric mechanical interfaces. The non-armored cable configuration also provides a relatively slim and flexible routing profile where additional mechanical protection is not required.
For a 5-meter 3300 XL system, correct component matching is especially important. The manufacturer documentation specifies that 5-meter probes are designed for use with the 5-meter Proximitor Sensor only.
Advantages
5-meter integrated cable
The 5.0 m cable length provides substantially more installation reach than 1 m, 1.5 m, or 2 m configurations. This can simplify installations where the monitoring electronics are located some distance from the machine.
Metric M10 x 1 mounting
The M10 x 1 thread provides a convenient mounting interface for machinery and assemblies using metric hardware. It also makes the 330193 family a practical alternative to the 3/8-24 UNF threaded 330191/330192 families when a metric installation is required.
Compact 20 mm case
The 20 mm overall case length helps accommodate installations where mounting depth is limited. The zero unthreaded-length configuration provides a particularly compact threaded mounting arrangement.
Non-armored cable design
The standard cable construction keeps the cable relatively small in diameter and flexible. This can make routing easier through confined instrumentation areas where armor is unnecessary.
8 mm non-contact sensing
The 8 mm sensing tip is designed for non-contact measurement of conductive rotating targets. Within a properly configured 3300 XL system, it can support important machinery protection measurements such as vibration and shaft position.
Defined 5-meter system architecture
The 5-meter probe is not simply a long cable option. It is part of a specific 3300 XL system configuration intended to operate with the matching 5-meter Proximitor Sensor. This system-level approach helps maintain the intended electrical performance of the transducer chain.
Practical replacement option
For maintenance teams replacing a 5-meter 3300 XL probe with an M10 x 1 mounting interface, the 330193-00-02-50-00 offers a clearly defined configuration that simplifies model selection when the original system specifications are known.
Technical FAQs
1. What is the Bently Nevada 330193-00-02-50-00?
It is a 3300 XL 8 mm ETR Proximity Probe with an M10 x 1 thread, 0 mm unthreaded length, 20 mm case length, and a 5.0 m total cable length.
2. How long is the 330193-00-02-50-00?
The total probe length is 5.0 meters (16.4 feet).
3. Is the 330193-00-02-50-00 armored?
No. The 330193 series is the M10 x 1, non-armored configuration. The 330194 family is the corresponding M10 x 1 armored configuration.
4. What thread does this probe use?
It uses an M10 x 1 metric thread.
5. What does the first “00” in the part number mean?
The first 00 specifies a 0 mm unthreaded length. For metric 3300 XL probes, the unthreaded length is ordered in 10 mm increments and must be at least 20 mm shorter than the case length.
6. What does “02” represent?
The 02 identifies the 20 mm overall case length configuration.
7. What does “50” mean in the model number?
The 50 specifies the 5.0 m (16.4 ft) total probe length. The 3300 XL ordering information lists 5.0 m as one of the available total-length options.
8. Can the 5-meter probe be used with a 9-meter Proximitor Sensor?
No. The manufacturer specifies that 5-meter probes are designed for use with the 5-meter Proximitor Sensor only. The probe and Proximitor Sensor should therefore be matched according to the intended system length.
9. What is the approximate size of the probe cable?
The standard 75 Ω cable has a maximum outside diameter of approximately 3.68 mm (0.145 in). The miniature male coaxial connector has a maximum diameter of approximately 7.24 mm (0.285 in).
10. What is the shipping weight of the 330193-00-02-50-00?
The listed shipping weight is approximately 1.5 kg. Actual shipping weight may vary slightly depending on packaging and order configuration.
