Hardware Specifications

Rotor Dynamics and Cross-Talk Suppression

The 330106 extension cable is integral to maintaining the system-wide impedance necessary for accurate rotor dynamics monitoring. The triaxial construction incorporates high-frequency shielding to ensure effective cross-talk suppression between adjacent transducer channels. When installed, the cable preserves the 7.87 V per mm (200 mV/mil) scale factor established by the probe and Proximitor pairing. Technicians must ensure that gap voltage validation is performed after installation; the target gap voltage at the probe tip should remain -10 VDC when the shaft is centered within the probe linear range to ensure measurement linearity.

Field Installation Protocols

• Cable Routing: Observe a minimum bend radius of 25 mm. Exceeding this limit can cause permanent damage to the coaxial core and shield.

• Connector Engagement: Tactile feedback is required when latching ClickLoc connectors. Ensure the locking mechanism is fully seated to prevent ingress of contaminants.

• Shield Continuity: The cable shield must remain continuous through the connector interface. Avoid grounding the cable shield at multiple points to prevent ground loops.

• Conduit Protection: Use flexible liquid-tight conduit for outdoor or harsh chemical environments to provide mechanical strain relief for the cable assembly.

Technical Frequently Asked Questions

• Can this extension cable be used with non-XL 3300 Proximitors?

  No. The 3300 XL system is impedance-matched as a set. Mixing non-XL components will result in incorrect scale factors and measurement drift.

• Is it possible to trim the cable to a shorter length?

  No. Trimming alters the calibrated impedance of the cable, which will invalidate the system output and cause significant errors in vibration readings.

• How should the connector be protected during pulls?

  Use the provided connector protector or a suitable pull-sock to prevent mechanical stress on the ClickLoc interface during cable routing through conduit.

• What is the maximum operating temperature for the cable jacket?

  The FEP jacket is rated for operation up to 177 deg C, provided the environment does not expose the cable to mechanical stress at these limits.

• Are there specific torque requirements for the connectors?

  No. ClickLoc connectors rely on a push-and-twist latch mechanism rather than threaded torque, though hand-tightening ensures the seal is fully seated.

• How is signal loss determined over 5 meters?

  The system is calibrated for a specific total length. Loss is negligible within the design length, provided the cable impedance remains within specified tolerances.

• Can this cable be used in vacuum applications?

  Yes. The materials used in the 330106 assembly are generally compatible with vacuum environments, provided they are clean and free of outgassing lubricants.

• What indicates an open circuit in the cable?

  An open circuit will cause the Proximitor to output a voltage near the negative supply rail (-24 VDC), signifying a loss of probe-to-sensor continuity.
