Configured for signal transmission between proximity probes and monitoring instrumentation in 3300 XL Series systems, the Bently Nevada 330103-00-16-10-12-05 (330103 Extension Cable) provides direct physical/electrical execution.

Part Number Configuration Matrix

The assembly follows the standard 3300 XL nomenclature:

• 330103: Base Model (Extension Cable)

• 00: Unarmored

• 16: 1.6 meters length

• 10: Connector protector kit included

• 12: Miniature coaxial connector

• 05: Agency approval option

Hardware Specifications

Eddy-Current Transducer Performance

The cable assembly maintains the 50 Ohm system impedance required for the 3300 XL transducer system to ensure accurate eddy-current probe scaling. This component facilitates precise gap voltage validation, targeting -10 VDC at the monitor input. Shielded construction provides cross-talk suppression, maintaining signal integrity required for rotor dynamics analysis. Insertion loss is controlled to prevent deviations in displacement measurement sensitivity during high-speed rotating machinery monitoring.

Installation Guidelines

• Routing

  • Install within rigid or flexible conduit to protect the coaxial jacket from mechanical abrasion.

  • Adhere to a minimum bend radius of 25 mm to prevent dielectric deformation.

• Termination

  • Clean all connector interfaces using a non-residue electronic cleaner prior to mating.

  • Tighten connectors by hand to ensure consistent electrical contact and maintain shielding continuity.

• Grounding

  • Ensure the transducer mounting assembly provides a low-impedance ground path to the machine casing to prevent ground loop interference.

Frequently Asked Questions

• Can this cable be used for legacy probe systems?

  This cable is specifically designed for 3300 XL transducer systems to maintain a 50 Ohm characteristic impedance. Use with other systems may cause calibration errors.

• Is it possible to splice this cable to increase length?

  No. Modifying the cable length alters the impedance and capacitance, which will negatively impact the frequency response and accuracy of the transducer output.

• What is the purpose of the connector protector?

  The connector protector provides environmental sealing at the interface between the probe cable and extension cable, preventing fluid ingress and oxidation.

• How should the cable be shielded?

  The outer jacket and internal shield are factory-integrated. Do not strip or alter the shielding; ensure the entire path remains unbroken back to the monitor.

• Does the cable require thermal insulation?

  The cable is rated for operation up to 177 deg C. It does not require additional insulation unless environmental temperatures exceed this specification.

• What does the -10 VDC target refer to?

  This is the standard baseline gap voltage for Bently Nevada proximity systems when the probe is at the designed electrical zero position.

• Can this cable be hot-swapped?

  The extension cable is a passive component. While it can be replaced, signal disruption will occur at the monitoring system during the disconnection process.

• How do I confirm the cable is functioning correctly?

  Verify the signal path using a multimeter to ensure continuity and check for correct gap voltage readings during system commissioning.
