Introduction
The Bently Nevada 330190-085-03-CN is a 3300 XL Extended Temperature Range (ETR) Extension Cable configured for demanding proximity monitoring installations where long cable routing, extended-temperature capability, enhanced connector protection, and country-specific approvals are important.
With an 8.5 m (27.9 ft) cable length, this configuration is one of the longer standard options in the 330190 ETR family. The -03 cable option identifies an armored cable with connector protectors, while the CN approval designation is intended for country-specific approval requirements. This combination makes the model particularly useful for installations where the cable needs additional mechanical protection and the connector ends require protection against harsh industrial conditions.
The 330190 ETR family is designed for use with the 3300 XL 8 mm proximity transducer system. Its PFA-insulated construction supports applications in which the extension cable may be exposed to temperatures beyond the standard cable rating, while the armored configuration provides a more robust solution for challenging cable-routing environments.
Technical Specifications
The 330190-085-03-CN ordering code can be understood by its configuration: 085 represents an 8.5 m cable, 03 identifies the armored cable with connector protectors, and CN denotes the country-specific approval option.

Applications
The 330190-085-03-CN is intended for 3300 XL proximity monitoring applications where the extension cable must bridge a relatively long distance between the proximity probe and the Proximitor Sensor.
Its 8.5-meter length can be especially useful when the monitoring electronics are installed away from the machine, in a separate instrumentation cabinet, or at a location selected to simplify maintenance access.
Typical applications include:
- Steam turbine vibration and shaft-position monitoring
- Gas turbine machinery protection
- Compressor monitoring systems
- Generator and rotating equipment protection
- Pump and motor condition monitoring
- Critical shaft displacement measurement
- Industrial machinery vibration monitoring
- High-temperature rotating equipment
- Hazardous-area machinery monitoring installations
- Long-distance proximity probe cable routing
The armored and connector-protected configuration is valuable in installations where the cable may encounter mechanical contact, abrasion, vibration, or other environmental stresses.
For system configuration, the extension cable should always be considered together with the selected proximity probe and Proximitor Sensor. The probe length plus extension cable length should correspond to the required Proximitor Sensor total system length.
Advantages
Extended 8.5-meter reach
The 8.5 m configuration provides substantial installation flexibility. It can accommodate equipment layouts where shorter extension cables would require additional routing changes or relocation of monitoring electronics.
ETR construction for high-temperature areas
The 330190 family is designed for applications where the extension cable may exceed the standard 177°C (350°F) temperature specification. Its ETR cable construction supports temperatures up to approximately 260°C (500°F).
Armored cable protection
The -03 configuration adds armor around the cable, helping protect the assembly in physically demanding installations. This can be particularly useful around turbines, compressors, and other machinery where cable routing is exposed to mechanical hazards.
Connector protection included
Unlike a basic standard cable configuration, the -03 option incorporates connector protectors. This gives the connection points additional environmental protection and can make the assembly better suited to demanding field installations.
Country-specific approval configuration
The CN suffix identifies a country-specific approval option. This can be important for projects where equipment documentation and approval requirements vary according to the installation location.
Designed around the 3300 XL system
The cable is not simply a generic replacement cable. Its defined electrical characteristics and connector arrangement are intended for the 3300 XL proximity transducer system, supporting proper integration with compatible probes and Proximitor Sensors.
Suitable for critical machinery protection
When paired with the correct probe and Proximitor Sensor, the 330190-085-03-CN provides a robust connection path within a machinery protection system where reliable proximity measurements are essential.
Technical FAQs
1. What is the Bently Nevada 330190-085-03-CN?
The 330190-085-03-CN is a 3300 XL Extended Temperature Range Extension Cable with an 8.5 m length, armored construction, connector protectors, and a country-specific CN approval configuration.
2. How long is the 330190-085-03-CN cable?
The cable length is 8.5 meters (27.9 feet).
3. What does the “085” in the part number mean?
The 085 portion identifies the cable-length option of 8.5 meters (27.9 feet) within the 330190 ordering system.
4. What does “03” mean in 330190-085-03-CN?
The 03 cable option identifies an armored cable with connector protectors. It provides more physical protection than the standard unarmored configuration.
5. What does the “CN” suffix indicate?
The CN suffix identifies a country-specific approval option. The exact approval requirements should be checked against the installation location and project documentation before ordering.
6. What temperature can the 330190 ETR extension cable withstand?
The 3300 XL ETR extension cable is designed for temperatures up to approximately 260°C (500°F). This extended-temperature capability is one of the main reasons to select the 330190 family instead of a standard 3300 XL extension cable.
7. Is the 330190-085-03-CN compatible with 3300 XL proximity probes?
It is intended for use within the 3300 XL 8 mm proximity transducer system. Final compatibility should be confirmed against the exact probe and Proximitor Sensor configuration because total probe and extension cable length is a key part of system selection.
8. What is the difference between 330190-085-03-CN and 330190-085-00-CN?
Both versions use the 8.5 m ETR cable length and CN approval option. The key difference is the cable construction: -00 is the standard cable configuration, while -03 is an armored cable with connector protectors.
9. What is the approximate weight of the 330190-085-03-CN?
The armored cable construction is approximately 103 g/m, resulting in an estimated cable mass of about 0.88 kg for 8.5 meters. Packaging and connector-specific variations can increase the shipping weight.
10. Why should the probe length and extension cable length be checked together?
The 3300 XL proximity system is configured around a defined total electrical length. The probe and extension cable lengths are intended to add up to the required Proximitor Sensor total length. Selecting an extension cable solely by physical reach can therefore result in an unsuitable system configuration.
