Introduction
The Bently Nevada 330192-10-95-90-CN is a 3300 XL 8 mm Extended Temperature Range (ETR) Proximity Probe designed for machinery monitoring applications that require dependable non-contact measurement in elevated-temperature environments. This armored probe configuration combines a 3/8-24 UNF threaded probe body with a long 9.0 m (29.5 ft) total cable length, making it well suited to large rotating machinery and installations where the monitoring electronics are positioned away from the machine.
The model is part of the 3300 XL ETR probe family and is engineered to work as part of a complete 3300 XL proximity transducer system. Its 1.5-inch unthreaded length, 9.5-inch overall case length, 9.0 m total length, and CN country-specific approval option define a highly specific configuration for replacement and new-installation requirements.
With armored cable protection and an extended-temperature probe design, the 330192-10-95-90-CN is a strong choice for turbine, compressor, generator, and other critical rotating-equipment applications where accurate shaft-position and vibration monitoring are essential.

Applications
The 330192-10-95-90-CN is designed for non-contact measurement of shaft vibration, radial position, axial position, and other dynamic machinery characteristics when used with the appropriate 3300 XL Proximitor Sensor and monitoring system.
Typical applications include:
- Steam turbine shaft monitoring
- Gas turbine vibration monitoring
- Turbo-compressor protection
- Generator rotor monitoring
- Centrifugal compressor applications
- Pump and motor shaft monitoring
- Bearing vibration measurement
- Thrust-position monitoring
- Critical rotating machinery protection
- High-temperature industrial machinery
The 9-meter system length is particularly useful on large machines where the proximity probe needs to be installed at the machinery while the Proximitor Sensor is located in a remote instrumentation cabinet or protected equipment area.
The armored cable construction is also advantageous where the cable route may be exposed to vibration, abrasion, mechanical contact, or other installation stresses.
Advantages
Extended-temperature performance
The ETR design allows the probe to operate in applications with substantially higher temperatures than conventional 3300 XL proximity probes. The probe itself is rated to approximately 218°C (425°F), while the associated ETR extension cable system supports higher cable temperatures where applicable.
Long 9-meter system configuration
The 9.0 m total length provides substantial flexibility for large machinery installations. It can reduce the need for additional cable routing modifications when monitoring electronics are positioned well away from the probe location.
Armored construction
The 330192 configuration incorporates armor around the probe cable, providing additional mechanical protection in demanding machinery environments.
8 mm non-contact measurement
The 3300 XL 8 mm probe design is intended for reliable non-contact measurement of conductive rotating targets. It is widely suited to machinery protection systems where shaft displacement and vibration information are critical.
Robust industrial materials
The probe uses a PPS sensing tip and stainless-steel probe-case construction, providing a durable mechanical package for industrial monitoring applications.
Defined system configuration
The combination of probe length, cable characteristics, and Proximitor Sensor compatibility allows the 330192-10-95-90-CN to be integrated into a properly configured 3300 XL proximity transducer system rather than treated as a generic proximity sensor.
Country-specific approval option
The CN suffix provides a country-specific approval configuration, making this version appropriate for projects where local certification or approval requirements need to be addressed as part of equipment selection.
Technical FAQs
1. What is the Bently Nevada 330192-10-95-90-CN?
The 330192-10-95-90-CN is a 3300 XL 8 mm Extended Temperature Range proximity probe with armor, configured with a 1.5-inch unthreaded length, 9.5-inch case length, and 9.0 m total system length.
2. What thread does the 330192-10-95-90-CN use?
This probe uses a 3/8-24 UNF-2A thread, making it part of the imperial-threaded 330192 ETR probe family.
3. What does “10” mean in the model number?
The 10 identifies the 1.5-inch unthreaded length option for this particular configuration.
4. What does “95” represent?
The 95 identifies the 9.5-inch overall case length option.
5. What does “90” mean?
The 90 specifies the 9.0-meter (29.5-foot) total probe length.
6. Does the 330192-10-95-90-CN have an armored cable?
Yes. The 330192 product family is the armored version of the 3300 XL 8 mm ETR probe with a 3/8-24 UNF thread.
7. What temperature can the probe withstand?
The ETR probe is designed for temperatures up to approximately 218°C (425°F) at the probe. The ETR cable is designed for a higher temperature range, depending on the specific section and installation conditions.
8. What is the diameter of the probe tip?
The sensing tip has a nominal diameter of 8.0 mm (0.31 in), consistent with the 3300 XL 8 mm proximity probe design.
9. How much does the 330192-10-95-90-CN weigh?
The listed probe weight is approximately 0.323 kg (323 g). The final shipping weight will depend on packaging and any additional supplied hardware.
10. Can this probe be used with a shorter extension cable?
The probe should be selected as part of the complete 3300 XL 8 mm proximity transducer system. The probe's 9.0 m configuration is associated with the appropriate system-length requirements, so simply combining it with an arbitrary extension cable is not recommended. The probe, extension cable, and Proximitor Sensor should be matched as a complete system.
