Bently Nevada 330106-05-30-20-02-CN 3300 XL 8mm Extension Cable

The Bently Nevada 330106-05-30-20-02-CN is a 3.0-meter 3300 XL armored extension cable designed for 8mm proximity probe systems. It features stainless steel armor, ClickLoc connectors, and a connector protector to ensure stable vibration monitoring in temperatures up to +177°C.

Technical Role and System Functionality

The Bently Nevada 330106-05-30-20-02-CN functions as the primary signal transmission link within a 3300 XL Proximity Transducer System. This specialized extension cable carries high-frequency eddy current signals between the 8mm proximity probe and the Proximitor Sensor. By maintaining a highly stable electrical impedance, the cable ensures that the 3500 Monitoring System receives precise data regarding shaft vibration and axial position. The 3300 XL series specifically incorporates advanced shielding and “ClickLoc” connector technology to prevent signal degradation in electrically noisy industrial environments.

Core Features and Industrial Benefits

Maintenance engineers choose the 05 armor option to safeguard the signal core against mechanical crushing, abrasion, and sharp bends in difficult routing paths. Furthermore, the stainless steel armor provides an extra layer of protection in high-vibration areas. Because the cable utilizes a chemical-resistant FEP jacket, it remains impervious to lubricating oils and corrosive fluids common in heavy machinery. Consequently, this cable is a standard choice for:

  • Steam and gas turbine bearing housing monitoring
  • High-speed centrifugal compressor protection
  • Cooling tower fan motor diagnostics
  • Hydro-turbine shaft alignment tracking

Installation and System Matching

Successful deployment requires that the user matches the extension cable length exactly to the system’s calibrated total length (typically 5.0 or 9.0 meters). For this 3.0-meter armored cable, the technician must verify the probe lead length to ensure the Proximitor Sensor operates within its linear range. Moreover, the 02 connector option includes a factory-installed connector protector. This component prevents conductive contaminants or moisture from entering the coaxial connection, which effectively eliminates the most common cause of “noise” in vibration signals.
