Introduction
The Bently Nevada 330194-00-08-10-00 is a 3300 XL 8 mm Extended Temperature Range (ETR) Proximity Probe featuring an M10 x 1 metric thread, 0 mm unthreaded length, 80 mm overall case length, and a 1.0 m (3.3 ft) total probe length.
Unlike the standard 330193 series, the 330194 series uses an armored cable construction, providing additional mechanical protection for installations where the probe cable may be exposed to vibration, abrasion, accidental contact, or demanding routing conditions.
Designed for integration with a compatible 3300 XL proximity transducer system, this 8 mm probe provides non-contact measurement of conductive rotating targets. It is well suited to machinery protection and condition-monitoring applications involving shaft vibration, radial position, and axial position.
The combination of M10 x 1 metric mounting, 80 mm case length, armored construction, and 1-meter system length makes the 330194-00-08-10-00 a practical choice when installation durability is just as important as measurement performance.

Applications
The 330194-00-08-10-00 is designed for non-contact monitoring of rotating machinery where a durable armored probe cable is preferred.
The probe can be used with a compatible 3300 XL Proximitor Sensor to create a complete proximity transducer system capable of monitoring shaft movement relative to the probe tip.
Typical applications include:
-
Steam turbine shaft vibration monitoring
-
Gas turbine machinery protection
-
Compressor vibration monitoring
-
Generator rotor monitoring
-
Centrifugal machinery monitoring
-
Pump and motor shaft measurement
-
Radial shaft-position monitoring
-
Axial shaft-position monitoring
-
Bearing vibration measurement
-
Critical rotating machinery protection
-
Industrial condition-monitoring systems
The 1-meter length is particularly convenient where the Proximitor Sensor is installed relatively close to the monitored machine. At the same time, the armored cable helps protect the connection between the machinery and instrumentation area.
The M10 x 1 metric thread also makes this model suitable for equipment designed around metric mounting arrangements.
Advantages
Armored cable protection
The most obvious advantage of the 330194 configuration is its armored cable. The additional protection makes the probe better suited to installations where cable damage is a realistic concern.
80 mm case length
The 80 mm case offers a useful middle ground between compact 20 mm configurations and much longer probe bodies. It can provide additional mounting flexibility without becoming excessively large.
Metric M10 x 1 thread
The M10 x 1 mounting interface provides a convenient solution for metric machinery and mounting assemblies. This makes the 330194 series particularly attractive for installations where imperial 3/8-24 UNF probes are unsuitable.
1-meter total length
The 1.0 m system length provides practical installation reach while keeping cable routing relatively compact. It is a good fit when the Proximitor Sensor is located near the machinery.
8 mm sensing tip
The 8 mm probe tip is designed for non-contact measurement of conductive targets. When correctly paired with the associated electronics, the system can provide important shaft vibration and position measurements.
Robust installation profile
The armored cable increases the overall cable diameter, but this trade-off can be worthwhile in installations exposed to mechanical interference, vibration, or abrasion.
Defined 3300 XL system configuration
The probe is designed to operate as part of a matched 3300 XL proximity transducer system. Correct selection of the probe, cable length, and Proximitor Sensor helps maintain the intended electrical characteristics of the measurement chain.
Strong replacement candidate
For maintenance teams replacing an existing M10 x 1 armored 3300 XL 8 mm probe with an 80 mm case and 1-meter length, the 330194-00-08-10-00 provides a highly specific configuration that makes replacement selection straightforward.
Technical FAQs
1. What is the Bently Nevada 330194-00-08-10-00?
It is a 3300 XL 8 mm ETR Proximity Probe with an M10 x 1 metric thread, armored cable, 0 mm unthreaded length, 80 mm case length, and 1.0 m total length.
2. Is the 330194-00-08-10-00 armored?
Yes. The 330194 series is the M10 x 1 armored version of the 3300 XL 8 mm probe. The corresponding non-armored family is 330193.
3. What thread does this probe use?
It uses an M10 x 1 metric thread.
4. What does the first “00” indicate?
The first 00 identifies the 0 mm unthreaded length configuration.
5. What does “08” represent?
The 08 identifies the 80 mm overall case length.
6. What does “10” mean?
The 10 specifies a 1.0 m (3.3 ft) total probe length.
7. What is the diameter of the probe tip?
The sensing tip has a nominal diameter of 8.0 mm (0.31 in).
8. How large is the armored cable?
The armored cable has an outside diameter of approximately 7.67 mm (0.302 in). The armor ferrule can reach approximately 9.5 mm (0.38 in) in diameter.
9. What is the approximate weight?
For planning purposes, the 1-meter armored assembly can be estimated at approximately 0.4 kg. Actual product and shipping weight may vary according to the finished configuration and packaging.
10. What should be checked before replacing this probe?
Confirm the M10 x 1 thread, 0 mm unthreaded length, 80 mm case length, 1.0 m total length, armored construction, connector arrangement, approval configuration, and compatible Proximitor Sensor. The complete 3300 XL transducer configuration should be checked rather than selecting a replacement based only on the 8 mm probe diameter.
