Bently Nevada 330730-080-00-CN: A Reliable Extension Cable for Proximity Monitoring Systems
The Bently Nevada 330730-080-00-CN is a precision-engineered extension cable. It is designed for the 3300 XL 11 mm proximity probe system. This component establishes a critical connection between the probe and the Proximitor Sensor. It ensures accurate signal transmission in industrial environments. Turbines, compressors, and pumps commonly use this system. The standard cable configuration offers a cost-effective solution. It maintains the high quality expected from Bently Nevada. Choosing this genuine part guarantees system compatibility. It also preserves measurement accuracy over time.
Technical Specifications and Performance
Key Electrical Parameters and Compliance
The 3300 XL 11 mm Extension Cable delivers consistent electrical performance over its length. This specific model, 330730-080-00-CN, measures 8.0 meters (26.2 feet) . Its typical capacitance is 69.9 pF/m (21.3 pF/ft) . The center conductor resistance is 2.0 ± 0.5 ohms. The coaxial conductor resistance is 0.6 ± 0.2 ohms. These values ensure reliable signal integrity. For optimal system performance, use a three-conductor shielded triad cable. The maximum allowable length between the sensor and monitor is 305 meters (1,000 feet) . Always consult the frequency response graph for long wiring runs.
Superior Materials for Durability and Protection
The cable features 75 Ω triaxial, fluoroethylene propylene (FEP) insulation. This material provides excellent dielectric properties. It also offers outstanding resistance to high temperatures. The operating and storage range spans -52°C to +177°C (-62°F to +351°F) . This makes it suitable for harsh thermal environments. Gold-plated brass ClickLoc connectors lock firmly into place. They prevent loosening from vibration and thermal cycling. The patented TipLoc and CableLoc technologies provide a robust bond. They deliver a pull strength of 330 N (75 lb) . This ensures long-term mechanical durability.
Standard Cable Configuration
This model features the "00" standard cable option. It does not include the FluidLoc or connector protector features. This configuration suits applications without oil exposure risks. It also works well in clean, dry environments. The standard cable remains fully compatible with all 3300 XL system components. It offers the same electrical performance as other variants. Users can add silicone tape for basic moisture protection. However, silicone tape is not recommended for turbine oil exposure.
Installation and Mechanical Details
Cable Weight and Handling
The unarmored extension cable weighs 45 g/m (0.5 oz/ft) . This makes it manageable during installation. The total weight for the 8.0-meter length is approximately 360 grams. An armored version is available for additional physical protection. It uses a flexible AISI 302 SST jacket with an FEP outer layer. However, this specific model comes in the standard configuration. The triaxial design and FEP insulation maintain signal integrity. This holds true even in electrically noisy industrial settings.
Installation Guidelines and System Integration
Set the probe gap to 2.5 mm (100 mils) during installation. The system's linear range extends from 0.5 mm to 4.5 mm (20 to 180 mils) . This corresponds to an output of approximately -1 to -17 Vdc. The extended DSL range reaches up to 5.0 mm (200 mils) . Note that this extended range does not apply with zener barriers. The Proximitor Sensors ship calibrated to AISI 4140 steel by default. Recalibration for other target materials is available upon request. Always follow the manufacturer's installation guidelines for best results.

Frequently Asked Questions
1. What is the exact length of the Bently Nevada 330730-080-00-CN cable?
This extension cable measures exactly 8.0 meters (26.2 feet) . The "080" in the product number indicates this length.
2. What does the "00" option mean in this product number?
The "00" indicates a standard cable configuration. This means it does not include the FluidLoc or connector protector options. It suits clean, dry applications without oil exposure.
3. Can I use this 3300 XL 11 mm Extension Cable with other probe types?
Bently Nevada recommends using genuine components for optimal performance. This cable works with all 3300 XL 11 mm probes. Always verify compatibility with your specific probe model.
4. What is the temperature range for this extension cable?
The 330730-080-00-CN operates within -52°C to +177°C (-62°F to +351°F) . This makes it suitable for most industrial applications.
5. Is the silicone tape sufficient for moisture protection?
Silicone tape provides basic moisture protection. However, Bently Nevada does not recommend it for turbine oil applications. For oil-exposed environments, consider the FluidLoc cable option instead.
