Machinery Monitoring and Rotor Dynamics Integration

The extension cable transfers high-frequency radio frequency (RF) signals between proximity probes and Proximitor sensors for intensive rotor dynamics analysis. Simultaneously, the low-resistance conductors allow the monitoring rack to execute accurate gap voltage validation, maintaining signal tracking close to target thresholds near -10 VDC. Consequently, the matched characteristic impedance limits insertion losses, preserving the calibrated eddy-current probe scaling factor of 200 mV/mil across the entire measurement loop. Furthermore, the outer braided copper layer combined with the flexible armor sleeve establishes superior cross-talk suppression and electromagnetic interference (EMI) protection, which eliminates signal distortion caused by surrounding machinery noise.

Frequently Asked Questions

Q: How does this specific cable length modify the overall eddy-current probe scaling?

A: The 4.0 m armored extension cable combines with a standard 1.0 m proximity probe to form a calibrated 5.0 m system. Technicians must connect it to a designated 5.0 m Proximitor sensor to maintain the target 200 mV/mil scale factor.

Q: What specific mechanical protection does the -01 suffix provide?

A: The -01 suffix indicates a flexible stainless steel armor layer that encases the internal coaxial line. This armor protects the internal 22 AWG conductors from physical crushing, abrasion, and hot fluid splashes inside the machine housing.

Field Installation Guidelines

• Clean the miniature ClickLoc coaxial connections with residue-free solvent before joining, ensuring positive metal-to-metal contact.
• Connect the male and female ClickLoc fittings together by hand until they click, avoiding the use of pliers or mechanical wrenches.
• Fasten the flexible stainless steel armor to structural enclosures using approved conduit clips to prevent loose cable whipping near rotating shafts.
• Isolate the cable shielding from any structural steel components except for the dedicated grounding terminal at the Proximitor sensor box to stop ground loop currents.
