Description

Bently Nevada 330730-080-02-00 3300 XL 11 mm Extension Cable

The Bently Nevada 330730-080-02-00 is a high-precision coaxial extension cable engineered for the 3300 XL 11 mm Proximity Transducer System. This specialized cable provides the electrical bridge between an 11 mm proximity probe and a compatible Proximitor sensor. It is a fundamental component of Turbine Supervisory Instrumentation (TSI), designed to facilitate non-contact measurement of vibration and axial displacement in large-scale industrial rotating machinery.

High-Performance Signal Transmission and Durability

Engineered for the most demanding physical environments, the 330730-080-02-00 ensures stable signal transmission over extended distances. Specifically, this model features a 304 stainless steel braided armor, which offers superior mechanical protection against crushing, abrasion, and sharp bends. Furthermore, the internal coaxial structure is designed to maintain consistent impedance, which is vital for the accuracy of eddy current measurements. As a result, operators can rely on precise data even in settings characterized by high electromagnetic interference (EMI) and heavy mechanical stress.

Technical Specification Matrix

Critical Asset Monitoring and Environmental Resilience

In sectors such as power generation, oil and gas, and heavy manufacturing, the 330730-080-02-00 plays a key role in machinery protection. Moreover, the FEP insulation provides comprehensive resistance to moisture, chemicals, and industrial oils. In addition, the 8.0-meter length is specifically calibrated to complete a 9.0-meter electrical system when paired with a 1.0-meter probe. Therefore, this extension cable is an essential asset for preventing unplanned downtime by providing the high-fidelity data required for predictive maintenance on steam turbines, compressors, and large pumps.

FAQ

What distinguishes the 11 mm system from the standard 8 mm system?

The 11 mm system used by the 330730-080-02-00 provides a wider linear range than the 8 mm version. Specifically, it is intended for applications where greater displacement measurements are expected or where a larger standoff distance between the probe and target is required.

How does the stainless steel armor benefit the installation?

The “02” option in the part number indicates fluid-sealed stainless steel armor. Furthermore, this armor protects the inner cable from being severed or damaged during installation in high-traffic areas or inside machine casings. Accordingly, it is the preferred choice for environments where the cable is exposed to physical hazards.

Can this cable be used with any Proximitor sensor?

No, it must be used with a 3300 XL 11 mm Proximitor. Consequently, if you attempt to use this cable with an 8 mm or 5 mm system, the calibration will be incorrect, leading to faulty vibration readings. Ultimately, always match the cable type to the specific transducer system series.

Is the cable resistant to extreme temperatures?

Yes, the 330730-080-02-00 is rated for operation up to +177 °C. As a result, it can be safely routed near hot turbine components without risk of insulation melting or signal degradation. In addition, it remains flexible at sub-zero temperatures, making it suitable for outdoor or cold-weather applications.
