Quick Detail

Description

The 330730-080-01-00 3300 XL 11 mm Extension Cable serves as a vital link within the high-performance transducer ecosystem, specifically engineered to maintain signal integrity over extended distances. As a primary component of the 3300 XL 11 mm Extension Cable series, this model is meticulously designed to facilitate the full-scale transition from legacy 7200-series 11 mm and 14 mm transducer systems to modern monitoring standards. When upgrading a plant’s infrastructure, it is critical to recognize that the 3300 XL 11 mm Extension Cable is not backward compatible with older sensors. To achieve the precision required for machinery protection, every single part of the loop must be replaced with dedicated 3300 XL 11 mm Extension Cable and matching proximity probe components.

The integration of the 330730-080-01-00 3300 XL 11 mm Extension Cable demands a holistic update of the machine’s monitoring suite. For operators utilizing the 3500 Monitoring System, simply installing the hardware is insufficient; the configuration software must be updated to a version that recognizes the 3300 XL 11 mm Extension Cable system as a verified input source. This ensures the digital logic correctly interprets the specialized voltage-to-gap scale factors unique to the 3300 XL 11 mm Extension Cable architecture. Furthermore, if the facility relies on older 3300 Monitoring Systems, a physical or firmware modification might be necessary. Consulting a technical representative is recommended to ensure the 3300 XL 11 mm Extension Cable functions seamlessly within your specific protective relay logic.

Applications

1.Signal Transmission for Large-Scale Displacement Monitoring

The primary application for this extension cable is to bridge the distance between a 3300 XL 11 mm Proximity Probe and the signal conditioning electronics. Because 11 mm systems are typically used for large-scale axial thrust and radial vibration monitoring on massive rotors (such as those in utility-scale steam turbines), this cable ensures that the high-frequency eddy current signals are transmitted with minimal loss. Its specific capacitance of 69.9 pF/m is tuned to maintain the calibration accuracy of the entire 11 mm transducer system over its 8.0-meter length.

2.Extreme Thermal Environment Routing

With an operating temperature range of -50°C to +175°C, this cable is designed to be routed through areas of extreme heat or cold. It is frequently applied in Steam Turbine enclosures where ambient temperatures far exceed the limits of standard industrial cables. Its ability to maintain a stable 45 Ω output resistance and consistent electrical properties at +175°C ensures that machinery protection data remains accurate, even when the cable is in direct proximity to high-pressure steam lines or hot bearing housings.

3.Integration with Proximitor and Monitoring Systems

The 330730-080-01-00 acts as the critical interface for field wiring, supporting conductors from 0.2 to 1.5 mm² (16 to 24 AWG) at the Proximitor end. Its low supply sensitivity ensures that any voltage fluctuations in the -16.5 Vdc to -25 Vdc power supply do not result in "noise" being misinterpreted as machinery vibration. This makes it a foundational component for any facility using Bently Nevada 3500 or 3300 Monitoring Systems to protect their critical rotating assets.

Specifications

Competitive Advantage

1.Robust Mechanical Protection via Integrated Armor

A primary advantage of the 330730-080-01-00 is its stainless steel armored jacket. Unlike standard cables that are susceptible to being pinched, cut, or crushed during heavy machinery maintenance, the armored design provides a high level of physical resilience. This significantly reduces the risk of signal loss or intermittent faults caused by cable damage in high-traffic or debris-prone industrial environments, ensuring maximum system uptime.

2.Exceptional High-Temperature Reliability

While many sensor cables fail as temperatures rise, the 330730-080-01-00 is rated for continuous operation up to +175°C (350°F). This makes it an industry-leading choice for routing through the hot sections of steam turbines and large compressors. The materials used in this cable are specifically chosen to prevent the insulation degradation and impedance shifts that occur in lesser cables when exposed to extreme heat, maintaining calibration accuracy across the entire temperature spectrum.

3.Precision-Matched Electrical Impedance

The cable is designed with a specific capacitance of 69.9 pF/m and an output resistance of 45 Ω, optimized specifically for the 3300 XL 11 mm system. This precise electrical matching ensures that the high-frequency eddy current signals are transmitted without reflection or distortion. This technical superiority allows for a Supply Sensitivity of less than 2 mV change per volt, providing the high-fidelity data needed for advanced diagnostics and predictive maintenance.

4.Secure and Vibration-Proof Connectivity

Featuring the patented ClickLoc connector system, this cable eliminates the need for lock-wiring or specialized tools to secure connections. The "click" provides an audible and tactile confirmation that the connection is locked, while the internal design prevents the connector from loosening under the intense structural vibrations common in large rotating equipment. This ensures long-term electrical continuity and prevents the "noise" spikes that can lead to false machinery trips.
