The Bently Nevada 330730-080-00-05 is a high-performance extension cable engineered specifically for the 3300 XL 11 mm proximity probe system. Primarily, this 3300 XL extension cable acts as the critical link between the probe and the Proximitor Sensor, enabling remote vibration and position monitoring. Furthermore, its standard cable configuration delivers reliable performance across a wide range of industrial environments.
This 11 mm extension cable features a length of 8.0 metres (26.2 feet), offering extended reach for installations where the Proximitor Sensor must be located away from the measurement point. Additionally, the connector and cable option "00" denotes a standard cable design without armor. Meanwhile, the cable construction utilizes a 75 Ω triaxial design with fluoroethylene propylene (FEP) insulation, which preserves signal fidelity even over longer runs.
Superior materials form the foundation of this cable's reliability. For instance, the extension cable material consists of FEP-insulated triaxial conductors, providing excellent dielectric properties and thermal stability. Moreover, all connectors feature gold-plated brass construction, ensuring low contact resistance and outstanding corrosion protection. Additionally, the ClickLoc connector design locks firmly into place, effectively preventing accidental disconnection due to vibration or thermal cycling.
The electrical parameters of this Bently Nevada extension cable are precisely controlled to maintain system accuracy. Specifically, the typical capacitance measures 69.9 pF/m (21.3 pF/ft), which is critical for proper Proximitor Sensor operation. Furthermore, the resistance from the center conductor to center conductor (RCORE) is 2.0 ± 0.5 ohms, while the resistance from the coaxial conductor to coaxial conductor (RJACKET) is 0.6 ± 0.2 ohms. Therefore, this 3300 XL series extension cable seamlessly integrates with the overall measurement chain.
This extension cable operates reliably across a broad temperature spectrum. To begin with, the operating and storage temperature range spans from -51°C to +177°C (-60°F to +351°F). However, exposing the cable to temperatures consistently below -34°C (30°F) may compromise the pressure seal's longevity. Besides this thermal consideration, the cable's FEP insulation provides excellent resistance to chemicals and moisture, making it suitable for demanding industrial settings.
Proper installation ensures optimal performance and service life. First, the ClickLoc connectors should be tightened finger-tight, with a maximum torque of 0.565 N•m (5 in•lb). Next, for field wiring between the Proximitor Sensor and the monitor, use three-conductor shielded triad cable ranging from 0.2 to 1.5 mm² (16 to 24 AWG). Finally, the maximum field wiring length is 305 meters (1,000 feet), though frequency response rolloff should be considered at extended distances.
The 3300 XL transducer system incorporates several innovative design elements. For instance, the patented TipLoc molding method creates a robust bond between the probe tip and the probe body, enhancing mechanical integrity. Meanwhile, the CableLoc design securely attaches the probe cable, providing 330 N (75 lb) pull strength. Additionally, silicone tape is supplied with each extension cable as an alternative to connector protectors. Nevertheless, this tape is not recommended for applications where the connection will be exposed to turbine oil.
Upon delivery, your package will include the following items:

1 x Silicone tape (for connector protection, where applicable)
1. What is the primary role of the Bently Nevada 330730-080-00-05?
This 3300 XL extension cable connects the 11 mm proximity probe to the Proximitor Sensor, extending the measurement system's reach while maintaining signal integrity.
2. What does the "00" connector and cable option signify?
The "00" option indicates this is a standard cable without the armored FluidLoc option, suitable for installations where mechanical protection is not a primary concern.
3. What is the total length of this extension cable?
The Bently Nevada 330730-080-00-05 has a length of 8.0 metres (26.2 feet).
4. What temperature range can this cable withstand?
The operating and storage range is -51°C to +177°C (-60°F to +351°F). Nevertheless, sustained exposure below -34°C should be avoided to protect the pressure seal.
5. Can I use silicone tape for connector protection with this cable?
Yes, silicone tape is included for this purpose. However, it is not recommended for environments where the connection will be exposed to turbine oil, as the tape may degrade in such conditions.
