Bently Nevada 330730-080-02-CN 3300 XL 11 mm Extension Cable
Product Introduction
The Bently Nevada 330730-080-02-CN serves as a critical component in the 3300 XL transducer system. This extension cable connects 3300 XL 11 mm probes to Proximitor Sensors, enabling accurate vibration and position measurements. Moreover, its robust construction ensures reliable signal transmission over extended distances.
Technical Specifications
The 330730-080-02-CN offers an 8.0-meter (26.2-foot) cable length, providing flexibility for various installation scenarios. This model features a standard cable configuration with a connector protector that safeguards connections in humid or moist environments. The country-specific agency approval option (CN) ensures compliance with regional regulatory requirements. Furthermore, this extension cable delivers a typical capacitance of 69.9 pF/m (21.3 pF/ft), maintaining signal fidelity across its length.
Cable Construction and Materials
This extension cable utilizes 75 Ω triaxial construction with fluoroethylene propylene (FEP) insulation. FEP offers excellent dielectric properties and chemical resistance, preserving signal integrity in harsh industrial settings. The connector protector adds an extra layer of defense against environmental contaminants. Additionally, each extension cable includes silicone tape as an alternative protection method, though we do not recommend using this tape in applications where the connection will contact turbine oil. Gold-plated brass ClickLoc connectors feature on all transducer system components. These connectors lock securely into place, effectively preventing accidental disconnection.
Agency Approvals and Compliance
The 330730-080-02-CN carries country-specific approvals (CN) that satisfy local regulatory standards. This certification ensures seamless integration into installations requiring regional compliance. The extension cable also meets rigorous performance standards for industrial monitoring applications.
Temperature and Environmental Ratings
This extension cable operates reliably across an exceptional temperature range, from -52°C to +177°C (-62°F to +351°F). This wide thermal tolerance suits both extreme cold and high-heat environments commonly found in turbine and compressor monitoring. The FEP insulation maintains its physical and electrical properties throughout this entire temperature spectrum, ensuring consistent performance.
Electrical Characteristics
The 330730-080-02-CN exhibits precise electrical specifications that guarantee measurement accuracy. The center conductor to center conductor resistance measures 2.0 ± 0.5 ohms, while the coaxial conductor to coaxial conductor resistance reads 0.6 ± 0.2 ohms. These low resistance values minimize signal loss over the 8.0-meter cable length. For field wiring, we recommend using three-conductor shielded triad cable with conductors sized from 0.2 to 1.5 mm² (16 to 24 AWG). The maximum field wiring length between the Proximitor Sensor and the monitor reaches 305 meters (1,000 feet). However, please consult the frequency response graph for signal rolloff considerations when using longer wiring runs.
Connector and Cable Features
Gold-plated brass ClickLoc connectors feature prominently in the 3300 XL transducer system design. These connectors lock firmly into place, ensuring a secure connection that resists vibration-induced loosening. The connector protector option provides additional protection for connectors in humid or moist environments. We recommend connector protectors for all installations, as they offer increased environmental protection. The silicone tape provided with each extension cable serves as an alternative, though we advise against using it where turbine oil exposure may occur.
Probe System Compatibility
The 330730-080-02-CN extension cable integrates seamlessly with the complete 3300 XL 11 mm probe system. The system features the patented TipLoc molding method, which creates a robust bond between the probe tip and the probe body. Additionally, the CableLoc design securely attaches the probe cable to the probe tip, providing an impressive 330 N (75 lb) pull strength. These engineering innovations ensure long-term reliability in demanding machinery monitoring applications. The probe itself comes in various case configurations, including armored and unarmored versions with ½-20, 5/8-18, M14 x 1.5, and M16 x 1.5 probe threads. Reverse mount versions offer either 3/8-24 or M10 x 1 threads.
FluidLoc Cable Option
3300 XL Probes and Extension Cables can also feature the FluidLoc cable option. This option prevents oil and other liquids from leaking out of the machine through the cable's interior. Such protection proves especially valuable in turbine and compressor applications where oil contamination poses a significant concern.
Installation Guidelines
Installing the 330730-080-02-CN extension cable requires attention to several key points. First, ensure the Proximitor Sensor calibration matches your target material. By default, factory calibration targets AISI 4140 steel, though we can provide calibration to other materials upon request. Next, connect the extension cable to the probe using the ClickLoc connector, ensuring it locks securely. Then, route the cable away from high-temperature surfaces and moving parts. Finally, apply the connector protector or silicone tape as appropriate. Avoid using silicone tape in turbine oil environments.
