Quick Detail

Description

The 330730-080-02-05 3300 XL 11 mm Extension Cable is a fundamental component of the advanced 3300 XL transducer series, specifically engineered to deliver high-fidelity signal transmission in the most demanding industrial environments. As a cornerstone of the 3300 XL 11 mm Extension Cable portfolio, this model is the primary solution for plants transitioning away from obsolete hardware. The 3300 XL 11 mm Extension Cable system was developed to replace legacy 7200-series 11 mm and 14 mm systems, offering vastly superior temperature stability and chemical resistance. When performing a system upgrade, it is essential to remember that the 3300 XL 11 mm Extension Cable requires a complete hardware overhaul; users must replace all existing probes, cables, and sensors with dedicated 3300 XL 11 mm Extension Cable components to maintain the integrity of the vibration and position data.

In addition to physical hardware changes, the integration of the 330730-080-02-05 3300 XL 11 mm Extension Cable necessitates a software-level update of the machinery protection rack. For facilities utilizing the 3500 Monitoring System, the configuration software must be updated to a version that recognizes the 3300 XL 11 mm Extension Cable as a certified input option. This ensures that the monitor correctly applies the unique scale factors and calibration curves associated with the 3300 XL 11 mm Extension Cable platform. For those maintaining the older 3300 Monitoring System, a specific hardware modification might be required to ensure compatibility with the 3300 XL 11 mm Extension Cable. We recommend contacting a technical specialist to verify that your rack settings are optimized for the 330730-080-02-05.

The 330730-080-02-05 3300 XL 11 mm Extension Cable distinguishes itself through its mechanical ruggedness, featuring a 8.0-meter length and high-performance armored cable construction.

Applications

1.High-Contamination and "Wet" Bearing Environments

The 330730-080-02-05 includes a factory-installed connector protector. This is essential for applications where the connection point is exposed to lubricating oil, moisture, or industrial solvents. The protector creates an environmental seal around the ClickLoc connector, preventing fluid ingress that could cause signal "drift" or intermittent grounding faults. This makes it the standard choice for internal bearing housing mounting where oil mist is constant.

2.Extreme Temperature Signal Preservation

With an operating temperature range of -55°C to +175°C, this cable is applied in thermal "hot zones" where standard coaxial cables would melt or become brittle. It is frequently routed alongside high-pressure steam lines or inside turbine enclosures. Its low 69.9 pF/m capacitance and high temperature stability ensure that the voltage-to-gap ratio remains accurate even as the surrounding environment fluctuates by hundreds of degrees.

3.Integration with Modern Monitoring Racks

This cable acts as the bridge to the plant's protective infrastructure. It supports field wiring from 0.2 to 1.5 mm², allowing it to interface easily with Bently Nevada 3500 series racks or standard PLCs/DCSs. Its extremely low supply sensitivity (<2 mV change) ensures that the vibration data reaching the control room is free from electrical noise, providing the high-fidelity data needed for automated machine trips and predictive diagnostics.

Specifications

Competitive Advantage

1.Integrated Environmental Shielding

The inclusion of a factory-installed connector protector provides a decisive advantage in harsh industrial settings. In environments saturated with oil mist, high humidity, or conductive dust, standard coaxial connections often suffer from signal leakage or corrosion. This integrated protector creates a hermetic-like seal over the ClickLoc connection, ensuring long-term signal stability and drastically reducing the occurrence of "false trips" caused by environmental contamination.

2.Global Interoperability with Multiple Approvals

A standout competitive feature of the 330730-080-02-05 is its Multiple Approvals certification (typically including ATEX, IECEx, and CSA). This makes the cable globally compliant for use in Zone 0, 1, and 2 hazardous areas. For multinational companies, this eliminates the need to source different regional variants, simplifying procurement and ensuring that safety standards are met regardless of the plant's geographical location.

3.Extreme Thermal Endurance

While standard industrial cables degrade at high temperatures, this 3300 XL cable is rated for continuous operation from -55°C to +175°C. This wide thermal window allows the cable to be routed through the hottest sections of a steam turbine enclosure without melting or becoming brittle. This resilience ensures that the 50 Ω output resistance and electrical properties remain consistent, preventing calibration drift during intense thermal cycling.

4.High-Fidelity Signal Transmission over 8.0 Meters

The 330730-080-02-05 is precision-tuned with a capacitance of 69.9 pF/m, specifically designed to maintain the frequency response of the 11 mm transducer system over its 8.0-meter length. This allows the Proximitor sensor to be mounted in a safe, accessible location far from the machine's high-vibration zones without sacrificing the accuracy of the vibration or axial position data.

5.Superior Noise Immunity and Sensitivity

With a supply sensitivity of less than 2 mV change per volt of input fluctuation, this cable is exceptionally resistant to electrical interference. In large plants with heavy electrical loads and variable frequency drives (VFDs), this high noise immunity ensures that the data reaching the monitoring rack is an accurate representation of the machine's mechanical state rather than electrical noise. This precision is vital for advanced predictive maintenance and automated safety shutdowns.
