Introduction
The Bently Nevada 330193-09-20-05-00 is a 3300 XL 8 mm ETR Proximity Probe configured with an M10 x 1 metric thread, 90 mm unthreaded length, 200 mm overall case length, and a 0.5 m (1.6 ft) total cable length.
This model belongs to the 330193 family of standard, non-armored metric 3300 XL 8 mm probes. Its relatively long 200 mm case and 90 mm unthreaded section make it a practical choice for machinery installations where a deeper mounting arrangement is required, while the short 0.5 m cable keeps the overall transducer assembly compact.
Designed for non-contact measurement of conductive rotating targets, the probe can be integrated into a compatible 3300 XL proximity transducer system for monitoring shaft vibration, radial position, axial position, and other critical machinery parameters.
Technical Specifications
The 330193-09-20-05-00 follows the standard 330193 ordering structure: 09 identifies the 90 mm unthreaded section, 20 specifies the 200 mm case length, 05 indicates the 0.5 m total length, and the final 00 represents the standard configuration without an agency approval option.

Applications
The 330193-09-20-05-00 is intended for applications requiring non-contact measurement of conductive rotating machinery targets. It becomes part of a complete 3300 XL proximity transducer system when paired with the appropriate Proximitor Sensor.
The 0.5 m cable length is particularly useful when the probe and monitoring electronics are located relatively close together. This helps avoid unnecessary cable loops and provides a neat installation in compact machinery-monitoring layouts.
Typical applications include:
-
Steam turbine vibration monitoring
-
Gas turbine shaft monitoring
-
Compressor machinery protection
-
Generator rotor monitoring
-
Pump and motor shaft measurement
-
Bearing vibration monitoring
-
Radial shaft-position measurement
-
Axial shaft-position measurement
-
Rotating equipment protection
-
Industrial machinery condition monitoring
The M10 x 1 metric thread makes this model suitable for installations using metric mounting hardware. Meanwhile, the 200 mm case length and 90 mm unthreaded section provide useful mechanical flexibility where a shorter probe body would not provide sufficient installation reach.
Advantages
Long 200 mm probe case
The 200 mm overall case length gives this model a substantially longer mechanical body than compact 20 mm or 80 mm configurations. This can be advantageous when the probe installation requires additional mounting depth.
90 mm unthreaded section
The 90 mm unthreaded length provides additional installation flexibility and allows the probe to accommodate specific machinery mounting arrangements where a longer exposed or clearance section is needed.
Compact 0.5-meter configuration
With a total length of only 0.5 m, this version is a good fit for installations where the Proximitor Sensor can be positioned close to the monitored equipment. It keeps cable routing straightforward without introducing unnecessary excess length.
Metric M10 x 1 mounting
The M10 x 1 thread makes the probe a convenient option for metric machinery and mounting hardware. It also provides a clear alternative to the 3/8-24 UNF threaded 330191/330192 families.
Standard non-armored cable
The non-armored construction keeps the cable slim and flexible. In a controlled installation environment where additional mechanical armor is unnecessary, this can simplify routing and installation.
8 mm sensing technology
The 8 mm sensing tip is designed for non-contact monitoring of conductive targets. When properly integrated with the 3300 XL system, it provides a practical solution for measuring shaft vibration and position.
Purpose-built ETR design
The ETR configuration is intended for machinery environments where temperature performance is an important consideration. This makes the 330193 family particularly suitable for demanding rotating-equipment installations.
Straightforward replacement selection
For maintenance applications where the existing probe is specified as M10 x 1 / 90 mm unthreaded / 200 mm case / 0.5 m, the 330193-09-20-05-00 provides a clearly defined replacement configuration without unnecessary cable length.
Technical FAQs
1. What is the Bently Nevada 330193-09-20-05-00?
The 330193-09-20-05-00 is a 3300 XL 8 mm ETR Proximity Probe with an M10 x 1 metric thread, 90 mm unthreaded length, 200 mm case length, and 0.5 m total cable length.
2. What thread does the probe use?
It uses an M10 x 1 metric thread.
3. What does “09” mean in the model number?
The 09 identifies the 90 mm unthreaded length.
4. What does “20” represent?
The 20 identifies the 200 mm overall case length.
5. How long is the 330193-09-20-05-00?
The nominal total probe length is 0.5 meter (1.6 feet).
6. Is the 330193-09-20-05-00 armored?
No. The 330193 family is the standard non-armored M10 x 1 configuration. The corresponding armored metric 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 type of cable does it use?
The probe uses a 75 Ω triaxial cable with a maximum standard cable diameter of approximately 3.68 mm (0.145 in).
9. What is the approximate weight of this probe?
For product and shipping planning, the assembly can be estimated at approximately 0.20 kg. Actual finished-product weight may vary slightly depending on production configuration and packaging.
10. What should be checked before replacing this probe?
Confirm the complete configuration, including M10 x 1 thread, 90 mm unthreaded length, 200 mm case length, 0.5 m total length, non-armored construction, connector type, approval configuration, and compatible Proximitor Sensor. Matching only the 3300 XL series or 8 mm tip diameter is not sufficient for a proper replacement.
