Introduction
The Bently Nevada 330180-90-CN is a 3300 XL Proximitor Sensor configured for a 9.0 m (29.5 ft) system length with panel mounting. It forms the signal-conditioning section of a complete 3300 XL 8mm proximity transducer system, working with a compatible proximity probe and extension cable.
The 3300 XL 8mm system uses eddy-current technology to provide a non-contact measurement of the distance between the probe tip and a conductive shaft surface. The resulting output can be used for both static shaft-position measurement and dynamic vibration monitoring, with common applications including fluid-film bearing machinery, turbines, compressors, generators, and Keyphasor-related speed or phase measurements.
The 90 in the ordering code identifies the 9.0 m panel-mounted configuration. The CN suffix identifies the country-specific agency approval option. For replacement work, the complete ordering code should be matched rather than selecting a Proximitor solely by its basic series number.
Technical Specifications
The 330180-90-CN is intended for installations where the Proximitor is mounted in a panel and the complete probe/extension-cable system requires a 9.0 m electrical length. The Proximitor accepts a compatible non-contacting 3300-series 5 mm, 3300 8 mm, or 3300 XL 8 mm proximity probe and extension cable.

Applications
Turbine Shaft Monitoring
The 330180-90-CN can be incorporated into turbine monitoring systems for continuous measurement of shaft movement, vibration, and position. Its 9.0 m configuration is useful where the monitoring cabinet is positioned some distance from the machine.
Compressor Monitoring
Compressors with suitable proximity-probe mounting locations can use the 3300 XL 8mm system to observe rotor movement and dynamic shaft behavior.
Generator Applications
Large generators can benefit from non-contact shaft-position and vibration measurement. The panel-mounted Proximitor provides a convenient interface between the machine-side transducer and centralized monitoring equipment.
Fluid-Film Bearing Machinery
The 3300 XL 8mm platform is primarily intended for vibration and position measurements on fluid-film bearing machines. It can also support Keyphasor reference and speed measurements when correctly configured.
Keyphasor and Speed Measurement
When paired with an appropriate probe arrangement, the system can provide a repeatable shaft reference for speed and phase-related measurements.
Machinery Protection
The Proximitor provides the conditioned electrical signal required by compatible machinery-monitoring and protection equipment, making it an important component in the measurement chain.
Retrofit Installations
The 330180-90-CN is a useful replacement-oriented configuration for existing 3300 XL systems where the original installation requires a 9.0 m panel-mounted Proximitor with the CN approval option.
Extended Cable Routing
Compared with 5.0 m versions, the 9.0 m configuration provides greater flexibility when the machine and monitoring cabinet are separated by a longer cable route.
Advantages
Extended 9.0 m Configuration
The primary installation benefit is the 9.0 m total system length, giving engineers additional freedom when positioning the Proximitor relative to the machine.
Panel-Mount Installation
The 90 configuration is specifically intended for panel mounting, making it a natural fit for centralized machinery-monitoring cabinets and retrofit control panels.
Non-Contact Sensing Architecture
The associated 3300 XL 8mm transducer system uses eddy-current technology, allowing shaft movement to be monitored without mechanical contact with the rotating target.
Flexible Probe Compatibility
The Proximitor accepts compatible 3300-series 5 mm, 3300 8 mm, and 3300 XL 8 mm proximity probes and extension cables, providing practical flexibility when maintaining an existing installation.
Compact Aluminum Construction
The A308 aluminum housing keeps the Proximitor relatively lightweight while providing a robust industrial package.
Wide Temperature Capability
With an operating temperature range of approximately -51°C to +100°C, the sensor can support demanding industrial machinery environments.
Low Current Consumption
Maximum current consumption is approximately 12 mA, making the Proximitor suitable for integration into compatible monitoring circuits.
Established 3300 XL Platform
The 3300 XL 8mm system combines the probe, extension cable, and Proximitor as a coordinated transducer chain, providing a well-defined approach to rotating-machinery measurement.
Country-Specific Approval Option
The CN suffix provides a distinct ordering configuration for projects requiring the applicable country-specific approval package. This is especially important when replacing equipment in regulated or hazardous-area installations.
Technical FAQs
1. What is the Bently Nevada 330180-90-CN?
It is a 3300 XL Proximitor Sensor configured for a 9.0 m (29.5 ft) system length with panel mounting and the CN country-specific approval option.
2. What does “90” mean in the model number?
The 90 identifies the 9.0 m system-length and panel-mount configuration.
3. What does “CN” mean?
The CN suffix identifies the applicable country-specific agency approval option for this configuration. The exact approval requirements should be matched to the installation before replacement.
4. Is 330180-90-CN a proximity probe?
No. It is the Proximitor Sensor. A complete 3300 XL 8mm transducer system consists of a compatible probe, extension cable, and Proximitor Sensor.
5. What probes are compatible with this Proximitor?
The Proximitor accepts one compatible non-contacting 3300-series 5 mm, 3300 8 mm, or 3300 XL 8 mm proximity probe and extension cable.
6. What is the total system length?
The specified system length is 9.0 m (29.5 ft). The total is determined by the compatible probe and extension-cable arrangement, not by the physical length of the Proximitor housing.
7. Is 330180-90-CN panel mounted?
Yes. The 90 configuration is the panel-mount version of the 9.0 m 330180 Proximitor family.
8. What are the dimensions and weight?
The Proximitor is approximately 81.3 × 61.2 × 63.5 mm and weighs approximately 246 g (0.246 kg). The complete system is typically around 0.7 kg.
9. What is the operating temperature range?
The published operating range is approximately -51°C to +100°C (-60°F to +212°F), with a storage range of approximately -51°C to +105°C (-60°F to +221°F).
10. How does 330180-90-CN compare with 330180-90-00?
Both are 9.0 m panel-mounted 3300 XL Proximitor configurations. The primary distinction is the final approval designation. The CN version is intended for the applicable country-specific approval configuration, while -00 represents a different approval option. For replacement work, the original suffix should be matched carefully rather than treating the two versions as automatically interchangeable.
