Bently Nevada 330730-080-11-00 Armored Extension Cable Overview

The Bently Nevada 330730-080-11-00 is an armored 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 11 specifies an armored FluidLoc cable construction. Agency approval option 00 indicates no special certifications are required. Therefore, this version suits general industrial environments without hazardous area requirements. The FluidLoc option prevents oil and other liquids from leaking out of the machine through the cable interior.

Technical Specifications

The Bently Nevada 330730-080-11-00 uses 75 Ω triaxial cable construction. Insulation material is fluoroethylene propylene (FEP) for excellent chemical resistance. The armored version includes flexible AISI 302 stainless steel armor with an FEP outer jacket. 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 temperature ratings for this cable. 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. Armored extension cable weighs 140 g/m (1.5 oz/ft) for the protected version. Therefore, the 8.0 meter cable weighs approximately 1.12 kg.

FluidLoc & Armor Features

The Bently Nevada 330730-080-11-00 includes the FluidLoc cable option. This option prevents oil and other liquids from leaking out of the machine through the cable interior. Consequently, it is ideal for turbine and compressor applications where oil migration is a concern. The armor provides mechanical protection against crushing, abrasion, and impact. Flexible AISI 302 stainless steel armor withstands harsh industrial environments. The FEP outer jacket adds additional chemical resistance.

All components of the transducer system use 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. 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.

Field Wiring & System Compatibility

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.

The 330730-080-11-00 is compatible with 3300 XL 11 mm probes and Proximitor sensors. System linear range for 11 mm probes is 4.0 mm (160 mils) . Linear range begins at approximately 0.5 mm (20 mils) from the target. The range extends from 0.5 to 4.5 mm (20 to 180 mils) corresponding to approximately -1 to -17 Vdc. Recommended gap setting is 2.5 mm (100 mils) for optimal performance.

Key Features & Benefits

Installation Guidelines

Follow these steps to install the Bently Nevada 330730-080-11-00 correctly. First, connect one end of the extension cable to the 3300 XL 11 mm probe. Second, ensure the ClickLoc connector locks with an audible click. Third, route the armored cable away from sharp edges and high heat sources. Fourth, secure the cable using appropriate clamps every 30 cm. Fifth, connect the other end to the Proximitor sensor input. Finally, verify the FluidLoc seals are intact before machine operation.

Do not bend the armored cable beyond its minimum bend radius. Use connector protectors in humid environments instead of silicone tape for turbine oil applications. The 330730-080-11-00 requires careful handling to maintain the FluidLoc sealing property.
