Bently Nevada 330730-080-00-00 Extension Cable Overview

The Bently Nevada 330730-080-00-00 is a 3300 XL 11 mm extension cable made in the USA. This cable connects between a 3300 XL 11 mm probe and its Proximitor sensor. The cable length option 080 provides 8.0 metres (26.2 feet) of reach. Connector and cable option 00 indicates standard cable construction. Agency approval option 00 also specifies standard cable without special certifications. Therefore, this version suits general industrial applications where no hazardous area approvals are needed. All components of the transducer system use gold-plated brass ClickLoc connectors.

Technical Specifications

The Bently Nevada 330730-080-00-00 uses 75 Ω triaxial cable construction. Insulation material is fluoroethylene propylene (FEP) for excellent chemical resistance. Extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. This low capacitance preserves signal integrity over long distances. For the 8.0 meter length, center conductor to center conductor resistance (RCORE) is 2.0 ± 0.5 ohms. Coaxial conductor to coaxial conductor resistance (RJACKET) is 0.6 ± 0.2 ohms. These consistent electrical properties ensure reliable performance.

Now consider the field wiring recommendations for the complete system. Use 0.2 to 1.5 mm² (16 to 24 AWG) wire for field connections. When using ferrules, the range becomes 0.25 to 0.75 mm² (18 to 23 AWG) . Three-conductor shielded triad cable is recommended for best performance. Maximum cable length between the Proximitor sensor and monitor reaches 305 meters (1,000 feet) . However, check the frequency response graph for signal rolloff at high frequencies when using longer lengths.

Mechanical Specifications

The Bently Nevada 330730-080-00-00 offers flexible installation options. Standard extension cable weighs 45 g/m (0.5 oz/ft) . Therefore, the 8.0 meter cable weighs approximately 360 grams. Armored extension cable is also available at 140 g/m (1.5 oz/ft) for harsh environments. However, this specific model uses standard unarmored construction. The cable material remains 75 Ω triaxial with FEP insulation throughout.

Probe tip material for the compatible 11 mm probes is Polyphenylene sulfide (PPS) . Probe case material is AISI 304 stainless steel (SST) . The probe cable specification uses 75 Ω triaxial, FEP insulated construction. Total probe lengths available are 1, 5, or 9 meters separately.

Temperature Range & Environmental Ratings

The Bently Nevada 330730-080-00-00 operates across an extremely wide temperature range. Operating and storage temperature spans -52°C to +177°C (-62°F to +351°F) . This wide range suits both freezing outdoor conditions and high-temperature machinery environments. The FEP insulation maintains flexibility and electrical properties across this entire range. Optional armor uses flexible AISI 302 stainless steel with an FEP outer jacket.

Connector & Cable Technologies

All components of the transducer system feature gold-plated brass ClickLoc connectors. These ClickLoc connectors lock into place when mated. As a result, they prevent the connection from becoming loose due to vibration. This feature is critical for rotating machinery applications. In addition, the patented TipLoc molding method provides a robust bond between the probe tip and the probe body. Furthermore, the probe cable attaches securely to the probe tip using the patented CableLoc design. This design provides 330 N (75 lb) pull strength for exceptional durability.

The 330730-080-00-00 can also be ordered with a FluidLoc cable option. This option prevents oil and other liquids from leaking out of the machine through the cable interior. Additionally, connector protectors provide extra protection in humid or moist environments. Silicone tape is also provided with each 3300 XL extension cable. However, silicone tape is not recommended in applications where the connection will be exposed to turbine oil.
