Configured for Specific Technical Task in System/Network Name, the Bently Nevada 330730-80-02-00 (330730 Extension Cable) provides direct physical/electrical execution. It acts as the critical coaxial transmission link that conveys high-frequency RF signals between an 11 mm proximity probe and a 3300 XL Proximitor sensor without introducing impedance mismatches or signal attenuation.

Code Sequence Parameter Selection

• 330730: Base model designation for the 3300 XL 11 mm Extension Cable family.
• -80: Cable Length Option defining a nominal span of 8.0 meters (26.2 feet).
• -02: Connector and Cable Option specifying a standard coaxial cable equipped with an integrated connector protector.
• -00: Agency Approval Option dictating no hazardous area approvals or certifications are required.

Hardware Specifications

Impedance Matching and Cross-Talk Suppression

The 330730-80-02-00 is engineered to maintain standard electrical properties that support proper eddy-current probe scaling within the complete 9.0 meters transducer system loop. Proper installation ensures the loop achieves the designated gap voltage validation targeting -10 VDC at the linear midpoint. The coaxial shielding architecture provides cross-talk suppression against adjacent high-voltage machinery lines, preserving the phase data precision needed to analyze dynamic rotor dynamics without distortion.

• 1 x Bently Nevada 330730-80-02-00 Extension Cable Assembly
• 1 x Integrated Coaxial Connector Protector Sleeve

Cable Routing and Interconnect Instructions

• Minimum Bend Radius Constraints

  Observe a minimum bend radius of 25.4 mm (1.0 inch) during structural routing to avoid causing internal insulation deformation or shielding separation.

• Connector Protector Deployment

  Slide the integrated silicone rubber protector over the mated ClickLoc connection point to shield the coaxial pins from moisture, oil, and atmospheric dust.

• Conduit Isolation Guidelines

  Run the extension cable through dedicated metal conduits separate from high-current AC lines to minimize external noise pickup and electromagnetic fields.

• Terminal Junction Box Shielding

  Terminate the cable shielding termination properly at the Proximitor housing ground bar, ensuring zero ground loops exist between the machine casing and the monitor rack.

Frequently Asked Questions

• Does this extension cable support hot-swapping while the monitoring channel loop is active?

  Yes, but disconnecting the coaxial junction immediately interrupts the circuit, forcing the monitor to read an open fault condition and suppressing downstream alarms.

• What happens to the eddy-current probe scaling if this 8.0-meters line is combined with a 9.0-meters probe?

  The system will experience severe impedance imbalances, which invalidates the scale factor and prevents the loop from achieving proper calibration.

• Can this specific extension cable line be modified or shortened manually in the field?

  No, altering the physical physical length changes the calibrated internal capacitance, which ruins the precision of the transducer system.

• How does the integrated connector protector modify the physical installation routine?

  It provides environmental sealing for the ClickLoc union, blocking out cutting fluids and oil mist commonly found around bearing housings.

• Does the 45 g/m weight parameter affect how the cable must be supported along structural runs?

  Yes, mechanical clips must secure the line every 1.0 meter to prevent high vibration fatigue from causing conductor wear.

• What baseline resistance value indicates that the internal conductor shielding remains intact?

  A center-to-shield resistance reading approaching infinity confirms the internal insulation layers have suffered no physical breach.

• Will this non-armored standard cable configuration tolerate direct exposure to high-pressure washdowns?

  No, the standard jacket needs the protection of an external conduit or junction box if exposed to direct water sprays.

• Can this option configuration be connected to older 3300 8 mm probe series?

  No, it is tuned solely for the electrical characteristics and dimensions of the 3300 XL 11 mm proximity sensor platform.
