Rotor Dynamics & Signal Transmission Integrity

The extension cable functions as a matched transmission line linking the 11 mm transducer probe to the proximitor monitor interface. Maintaining exact system length matching is critical to preserve the nominal 3.94 V/mm (100 mV/mil) sensitivity and prevent phase distortion in high-speed rotor dynamics monitoring. The integrated shield construction and proper grounding protocols suppress cross-talk across multi-channel monitor assemblies, ensuring stable gap voltage validation against the -10 VDC operational baseline.

Field Wiring & Physical Routing Directives

• Length Synchronization: Verify that the combined length of the probe and extension cable matches the calibrated input range of the proximitor driver.
• Connector Seating: Fasten the ClickLoc gold-plated coaxial connectors securely until a distinct click is felt to prevent loosening from machine vibration.
• Environmental Protection: Position the included connector protectors completely over joint interfaces to block moisture and fluid ingress.
• Routing Geometry: Secure the armored cable along designated pathways while maintaining safe bend radii to avoid internal conductor fatigue.

Frequently Asked Questions and Technical Responses

• What is the nominal characteristic resistance of this extension cable model?

  The inner conductor loop maintains a standard 50 Ohm impedance to match system requirements.

• Does this cable require active power feeds from the monitor rack?

  No, it operates entirely as a passive analog signal transmission line driven by the proximitor sensor.

• How does the cable capacitance affect high-frequency response?

  The nominal capacitance of 69.9 pF/m is factored into the factory calibration to preserve signal fidelity.

• What protection features are included with option code 13?

  It includes mechanical armor shielding alongside FluidLoc construction and integrated connector protectors.

• Can this extension cable be shortened in the field during installation?

  No, altering the physical cable length invalidates the impedance match and system calibration scaling.

• What is the maximum continuous temperature limit for the cable jacket?

  The fluorocarbon insulation withstands continuous thermal exposure up to +177 deg C.

• Why is complete connector seating critical during assembly?

  Incomplete connection introduces high-frequency resistance, causing erratic gap voltage readings and false alarms.

• Are extension cables from 7200 series systems compatible with 3300 XL components?

  No, 3300 XL components require matching 3300 XL architecture to ensure correct electrical impedance and scaling.
