The Bently Nevada 330730-040-11-05 is a high-quality extension cable specifically designed to complement the 3300 XL 11 mm proximity probe system. Primarily, this 3300 XL extension cable bridges the probe and the Proximitor Sensor, enabling remote monitoring of critical machinery. Furthermore, its armored construction and FluidLoc technology offer superior protection against harsh operational conditions.
This 11 mm extension cable comes with a length of 4.0 meters (13.1 feet), providing flexible installation options. Additionally, it features the Armored FluidLoc cable option, which effectively prevents oil and other liquids from escaping through the cable interior. For instance, this design is particularly valuable in steam turbine and compressor applications where fluid ingress is a common concern. Meanwhile, the connector and cable type is designated as "11", confirming the presence of this robust FluidLoc armor.
Durability is a cornerstone of this cable's design. Specifically, the armor consists of flexible AISI 302 stainless steel (SST) wrapped with a FEP outer jacket, delivering excellent mechanical protection. Moreover, the connectors are fabricated from gold-plated brass, ensuring reliable electrical contact and corrosion resistance. Besides this, the cable itself is a 75 Ω triaxial type with fluoroethylene propylene (FEP) insulation, which preserves signal quality over its entire length.
The electrical characteristics of this Bently Nevada extension cable are precisely defined. For example, its typical capacitance is 69.9 pF/m (21.3 pF/ft), which is critical for maintaining system accuracy. Furthermore, the resistance from the center conductor is 1.0 ± 0.25 ohms. In terms of environmental tolerance, the operating and storage temperature range spans from -51°C to +177°C (-60°F to +351°F). However, users should avoid exposing the cable to temperatures below -34°C (30°F) to prevent premature seal failure.
Proper handling during installation ensures long-term reliability. To begin with, the extension cable's tensile strength is rated at 270 N (60 pounds) at the connectors, so avoid pulling with excessive force. Additionally, this 3300 XL series extension cable is compatible with system lengths of 5 or 9 meters when combined with the probe. Finally, field wiring between the Proximitor and the monitor can extend up to 305 meters (1,000 feet), using three-conductor shielded triad cable (0.2 to 1.5 mm² / 16 to 24 AWG).
The 330730-040-11-05 comes with additional protective accessories. For instance, silicone tape is provided with each extension cable to serve as an alternative to connector protectors. Nevertheless, this tape is not recommended for applications where the connection point will be exposed to turbine oil. Therefore, for oily environments, the integrated FluidLoc armor and optional connector protectors offer a more robust solution. Besides this, all 3300 XL probes include a locknut with pre-drilled safety wire holes as standard.
Upon delivery, your package will include the following items:
1 x Bently Nevada 330730-040-11-05 3300 XL 11 mm Extension Cable (Armored FluidLoc, 4.0m)
1 x Silicone tape (for connector protection, where applicable)
1. What is the primary function of the Bently Nevada 330730-040-11-05?
This 3300 XL extension cable connects the 11 mm proximity probe to the Proximitor Sensor, extending the reach of the measurement system while maintaining signal integrity.
2. What does the "FluidLoc" option mean for this cable?
The FluidLoc design prevents oil and other process liquids from leaking out of the machine through the cable's interior, making it ideal for turbine and compressor installations.
3. What is the total length of this armored extension cable?
The Bently Nevada 330730-040-11-05 has a length of 4.0 meters (13.1 feet).
4. Is this cable suitable for high-temperature environments?
Yes, the operating and storage temperature range is -51°C to +177°C (-60°F to +351°F). However, consistent exposure below -34°C should be avoided to protect the seal.
5. Can I use silicone tape instead of connector protectors with this cable?
Yes, silicone tape is provided for this purpose. Nevertheless, it is not recommended for environments where the connection will be exposed to turbine oil, as the tape may degrade.
