330104-00-10-90-02-00 | Bently Nevada | 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330104-00-10-90-02-00 is a brand new, original 3300 XL 8 mm proximity probe configured with an integrated, heavy-duty armored cable. This high-precision hardware uses eddy current technology to measure static (distance) and dynamic (vibration) shaft displacement on critical rotating machinery. The 9.0-meter continuous cable length transmits clear signals directly to a compatible 9-meter Proximitor sensor, bypassing the need for intermediate extension cables. This model safeguards high-speed turbomachinery, including centrifugal compressors, steam turbines, and large industrial pumps, from catastrophic mechanical failure.

Part Number Breakdown

Bently Nevada builds this specific hardware configuration to meet precise mechanical routing and physical protection constraints:

Engineering Advantages

• Eliminates Intermediate Connection Vulnerabilities: The 9.0-meter continuous cable architecture creates a direct run from the probe tip to the monitoring enclosure. Removing the traditional intermediate extension cable junction eliminates common signal degradation points caused by moisture ingress, oil contamination, and terminal corrosion.

• Defends Against Mechanical Shearing: The integrated stainless steel armor sleeve completely encloses the internal coaxial cable. This protective layering shields the delicate conductor wire from sharp metal edges, flying debris, and accidental crushing inside the machine housing or junction conduit.

• Simplifies Deep-Housing Adjustments: The 100 mm fully threaded case allows precise mechanical gap tuning. Engineers screw the probe directly through thick-walled bearing casings or bracket assemblies, achieving the exact voltage bias point without stacking adjustment washers.

• Locks Interconnections Automatically: The patented ClickLoc miniature coaxial connector uses an internal detent mechanism. Field technicians slide and click the connector together by hand, creating a high-tensile joint that withstands continuous high-frequency frame vibration without loosening.

FAQs

• Can I connect this 9.0-meter probe to a 5-meter Bently Nevada Proximitor sensor?

  No. Transducer calibration relies strictly on total system length. Connecting a 9.0-meter probe to a 5-meter Proximitor sensor causes severe impedance mismatch, which alters the scale factor and corrupts the vibration data. You must pair this probe with a dedicated 9-meter 3300 XL Proximitor sensor.

• Does this 9.0-meter armored cable support field-splicing if a section suffers damage?

  No. You cannot splice or patch high-frequency eddy current sensor lines in the field. Splicing alters the electrical resistance and core inductance of the coaxial path, destroying the system's factory calibration. Replace the entire probe unit if the internal conductor fails.

• What are the key precautions regarding the minimum bend radius of the armored cable?

  Maintain a minimum static bend radius of 25.4 mm (1.0 inch) for the armored section during installation routing. Forcing the armor sleeve into sharp angles kinks the inner coaxial line, damaging the shielding layer and generating signal noise on your monitoring rack.
