The Bently Nevada 330730-080-02-00 is an 8-meter non-armored extension cable for 3300 XL 11mm proximity systems. It features integrated silicone boots for enhanced environmental sealing and reliable signal transmission.
The Bently Nevada 330730-080-02-00 operates as a high-fidelity signal conduit for the 3300 XL 11mm Proximity Transducer System. This extension cable facilitates the transmission of raw displacement data from the 11mm proximity probe to the Proximitor sensor. By maintaining a strictly controlled electrical impedance across its entire length, the cable prevents signal distortion, ensuring the monitoring system receives an accurate representation of the mechanical movement within large-scale rotating equipment.
Furthermore, the 330730-080-02-00 features a non-armored design that prioritizes flexibility for routing through complex conduit systems or tight machine housings. This specific variant includes a specialized 1.0-meter silicone boot over the connectors, which provides an extra layer of environmental sealing. This boot effectively blocks the ingress of moisture, oil, and corrosive contaminants, thereby preserving the electrical integrity of the connection in the humid or oily atmospheres typical of turbine decks.
This extension cable actively supports comprehensive machinery protection by delivering clean, low-noise signals to the 3500 Monitoring System. Consequently, operators can monitor critical parameters such as axial thrust and radial vibration in real-time. Because the 11mm system offers a wider linear range than standard 8mm systems, this cable is particularly vital for large-scale assets where thermal expansion or significant shaft movement is anticipated.
Key industrial applications include:
To ensure a secure link, Bently Nevada utilizes patented ClickLoc connectors that snap together with a vibration-resistant lock. This mechanism prevents the signal attenuation that occurs if standard connectors loosen due to the high-frequency mechanical oscillations found near bearing housings. Additionally, the cable’s advanced shielding effectively rejects electromagnetic interference (EMI), allowing for precise measurements even in electrically “noisy” environments like power plants or chemical refineries.
The Bently Nevada 330730-080-00-00 functions as a high-precision signal conduit within the 3300 XL 11mm Proximity Transducer System. This specific cable model enables the seamless transmission of displacement and vibration data from the proximity probe to the Proximitor sensor. By maintaining a constant electrical impedance, the cable ensures that the monitoring system captures accurate mechanical data from high-speed rotating assets.
Technicians primarily deploy the 3300 XL 11mm system when an application requires a broader linear range than standard 8mm sensors can provide. Consequently, this extension cable becomes a critical component in monitoring large-scale machinery where shaft movement or clearances are more substantial.

Beyond basic signal relay, the 330730-080-00-00 extension cable actively supports predictive maintenance strategies. By delivering high-fidelity vibration signals, the cable allows the diagnostic system to identify early-stage faults such as bearing wear, rotor imbalance, or shaft misalignment. Furthermore, this proactive data stream helps operators avoid catastrophic mechanical failures and reduces the high costs associated with unplanned downtime.
Specific applications include:
Monitoring axial position and radial vibration in large steam or gas turbines.
Tracking shaft displacement in high-capacity centrifugal compressors.
Providing phase reference signals via Keyphasor integration for speed and timing analysis.
Bently Nevada manufactures the 330730-080-00-00 to withstand the rigorous thermal and chemical conditions found in power plants and refineries. Although this version lacks external armor, the high-quality jacketing material provides excellent flexibility and chemical resistance. Additionally, the patented ClickLoc connectors facilitate a secure, vibration-proof connection. These connectors snap firmly into place, ensuring that electrical continuity remains intact even when the machinery experiences intense high-frequency oscillations.
