Introduction
The Bently Nevada 330193-00-08-10-00 is a 3300 XL 8 mm Extended Temperature Range (ETR) Proximity Probe configured with an M10 x 1 metric thread, an 80 mm overall case length, and a 1.0 m (3.3 ft) total probe length. This standard, non-armored configuration is designed for machinery monitoring installations that require a metric mounting interface together with a longer probe case than the compact 20 mm configurations.
As part of the 3300 XL 8 mm proximity transducer family, the probe provides non-contact measurement of conductive rotating machinery targets. When correctly paired with a compatible 3300 XL Proximitor Sensor, it can be used for monitoring shaft vibration, radial position, axial position, and other dynamic machinery characteristics.
The 80 mm case length gives the 330193-00-08-10-00 a useful mechanical profile for applications where additional probe engagement is needed. Combined with its 1-meter total electrical length and non-armored cable, it offers a practical balance between mounting flexibility, compact cable routing, and reliable proximity measurement.
Technical Specifications
The model number identifies the mechanical and electrical configuration of this specific 330193 probe. 330193 designates the M10 x 1, non-armored 3300 XL 8 mm ETR probe family; 00 specifies a 0 mm unthreaded length; 08 identifies an 80 mm overall case length; 10 specifies a 1.0 m total length; and the final 00 indicates that no agency approval option is required. The 3300 XL ordering system defines metric probe case lengths in 10 mm increments and requires the unthreaded section to be at least 20 mm shorter than the case length.

Applications
The 330193-00-08-10-00 is intended for integration into 3300 XL 8 mm proximity transducer systems used to measure the position and movement of conductive machinery targets without physical contact.
The system's output is proportional to the distance between the probe tip and the observed conductive surface, allowing both static position and dynamic vibration measurements. Typical applications include fluid-film bearing machinery, rotating shafts, and Keyphasor-related speed or reference measurements.
Typical applications include:
- Steam turbine shaft monitoring
- Gas turbine machinery protection
- Compressor vibration monitoring
- Generator rotor monitoring
- Pump and motor shaft measurement
- Radial shaft-position monitoring
- Axial-position measurement
- Bearing vibration monitoring
- Critical rotating machinery protection
- Machinery condition-monitoring systems
The M10 x 1 thread makes this configuration especially suitable for metric mounting arrangements. Its 80 mm case length can also be useful where a longer threaded probe body is required for the mechanical installation.
Because the 3300 XL system consists of a probe, extension cable, and Proximitor Sensor, the probe should be selected as part of the complete transducer configuration rather than by mechanical dimensions alone.
Advantages
Extended case configuration
The 80 mm case length provides more mounting depth than the compact 20 mm configuration. This can be valuable when the machinery installation requires a longer probe body or a different mounting position.
Metric M10 x 1 mounting
The M10 x 1 thread provides a straightforward metric mounting interface for equipment designed around metric mechanical standards. It also distinguishes the 330193 family from the 3/8-24 UNF versions in the 330191 and 330192 families.
1-meter system length
The 1.0 m total length is well suited to installations where the Proximitor Sensor can be positioned relatively close to the monitored machine. It avoids unnecessary cable length while maintaining the defined electrical characteristics of the 3300 XL system.
Slim non-armored cable
The standard, non-armored construction uses a 3.68 mm maximum cable diameter, giving the probe a relatively small routing profile. This is useful where the cable passes through confined instrumentation spaces and additional armor is not required.
8 mm non-contact measurement
The 8 mm probe tip is designed for non-contact measurement of conductive targets. Within the properly configured 3300 XL system, it supports both static shaft-position and dynamic vibration measurements.
Interchangeable system architecture
The 3300 XL platform is designed around interchangeable probes, extension cables, and Proximitor Sensors, reducing the need for individual component bench calibration when compatible 3300 XL components are used together.
Practical replacement choice
For maintenance teams working with a metric mounting arrangement and an existing 1-meter 3300 XL system, the 330193-00-08-10-00 offers a clearly defined combination of M10 x 1 mounting, 80 mm case length, 8 mm sensing, and standard cable construction.
Technical FAQs
1. What is the Bently Nevada 330193-00-08-10-00?
It is a 3300 XL 8 mm ETR Proximity Probe with an M10 x 1 thread, 0 mm unthreaded length, 80 mm overall case length, and 1.0 m total probe length.
2. What thread does the 330193-00-08-10-00 use?
The probe uses an M10 x 1 metric thread. It belongs to the 330193 family of non-armored metric 3300 XL 8 mm probes.
3. What does the first “00” indicate?
The first 00 identifies a 0 mm unthreaded length. The 3300 XL metric ordering system allows unthreaded lengths in 10 mm increments, with the maximum unthreaded section limited by the case length.
4. What does “08” mean in the model number?
The 08 identifies the 80 mm overall case length configuration.
5. How long is the 330193-00-08-10-00?
Its nominal total probe length is 1.0 meter (3.3 feet). The published total-length tolerance is +30% / -0%.
6. Is this probe armored?
No. The 330193 series is the M10 x 1 non-armored configuration. The corresponding armored metric ETR family is 330194.
7. What is the probe-tip diameter?
The sensing tip has a nominal diameter of 8.0 mm (0.31 in).
8. What is the cable diameter?
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).
9. Does the 1-meter probe require a specific Proximitor Sensor?
The probe should be paired with the appropriate 3300 XL Proximitor Sensor as part of the complete system configuration. The 3300 XL architecture defines system performance through the matched probe, extension cable, and Proximitor Sensor combination.
10. What should be checked when replacing this probe?
Before replacement, verify the M10 x 1 thread, 80 mm case length, 0 mm unthreaded length, 1.0 m system length, non-armored construction, connector configuration, and approval requirement. It is also important to confirm the associated Proximitor Sensor and complete system configuration rather than matching the probe by physical appearance alone.
