Hardware Specifications

Mechanical Monitoring and Signal Integrity Architecture

Engineered for precision machinery protection infrastructure, this extension cable maintains exact eddy-current probe scaling by preserving the electrical impedance characteristics required by matched transducer sets. Proper gap voltage validation ensures that the downstream monitor reads a steady -10 VDC baseline at nominal clearance. Continuous coaxial shielding suppresses external electromagnetic noise, preventing cross-talk and preserving signal fidelity during high-speed rotor dynamics evaluations.

Field Installation Guidelines

• Bend Radius Compliance: Maintain a minimum bend radius of 25.4 mm along the coaxial run to prevent structural degradation of the inner dielectric core.
• Shield Termination: Ground the outer metallic shield exclusively at the instrument rack monitor termination point to prevent ground loop currents.
• Mechanical Coupling: Fasten coaxial connectors securely until the ClickLoc latch mechanism fully engages to eliminate intermittent signal dropouts.
• Routing Separation: Keep signal cabling routed in dedicated metallic conduits entirely isolated from high-voltage AC motor drives and power lines.

Frequently Asked Questions

• What is the explicit function of this extension cable within a vibration monitoring circuit?

  It bridges the physical distance between the probe lead and the proximitor sensor while maintaining matched electrical capacitance across the loop.

• Can the cable length be cut or spliced if it exceeds the required routing distance?

  No. Altering the physical length of a calibrated coaxial assembly modifies circuit impedance, introducing severe linearity errors in output readings.

• What connector type is utilized at both termination ends of the cable?

  It employs miniature coaxial ClickLoc connectors equipped with gold-plated contacts to secure the connection against high machine vibration.

• How does the assembly withstand elevated temperatures inside turbine enclosures?

  The fluoropolymer outer jacket and specialized high-temperature insulation allow continuous operation up to +177 deg C.

• Why are connector protective boots mandated on the coupling interfaces?

  They seal the junction to block industrial oils, moisture, and conductive debris from degrading high-frequency radio frequency signals.

• Does this passive extension cable require an external power supply connection?

  No, it operates entirely as a passive transmission line carrying radio frequency signals generated by the proximitor sensor unit.

• What induces signal attenuation or erratic gap voltage behavior along the run?

  Damaged coaxial shielding, loose mechanical connectors, or internal conductor fractures caused by excessive pulling tension during installation.

• Is intermediate grounding permitted along the run of the extension cable?

  No, intermediate grounding is strictly prohibited; the shield must terminate only at the system monitor ground bar to eliminate noise coupling.
