- Connector type: Mini‑Dot male‑female gold‑plated brass connectors
- Material Composition: High‑purity copper inner conductor; FEP fluoropolymer dielectric insulation; multi‑layer copper triaxial shielding network; AISI 302 stainless‑steel flexible armor braid; high‑temperature‑resistant outer polymer jacket; gold‑plated brass Mini‑Dot male‑female connector assemblies at both cable ends.
- Structural Features: Flexible triaxial cable main‑body fully covered by continuous stainless‑steel armor braid; probe‑side Mini‑Dot female connector; proximitor‑side Mini‑Dot male connector; reinforced strain‑relief sections at cable‑connector junctions; multi‑layer shielding runs through complete cable length.
- Working Principle: Armored triaxial extension cable serves as high‑frequency signal transmission path inside eddy‑current transducer chain. It forwards proximitor‑generated high‑frequency excitation signal to field‑mounted proximity probe, and feeds back probe‑coil impedance‑variation signal back to proximitor sensor. Stainless‑steel armor absorbs external mechanical stress without disturbing internal triaxial electrical performance. Stable 75‑ohm impedance guarantees measurement‑loop signal integrity.
- Application Scenarios: Field locations with high cable‑abrasion risk for 3300‑XL transducer chains; compressor and turbine measuring‑points requiring mechanical‑robust cabling; petrochemical plant TSI monitoring systems; spare‑part replacement for armored‑cable configured legacy 3300‑XL installations.
- Installation Requirements: Connect female Mini‑Dot end to probe‑integral‑cable plug; connect male Mini‑Dot end to proximitor socket; fully tighten Mini‑Dot locking ring; observe minimum bending‑radius requirement for armored cable assembly; route armored extension cable inside dedicated cable‑tray separated from high‑power‑cable routes; implement single‑end grounding for cable shielding layers; sum length of probe integral‑cable plus extension‑cable must conform to proximitor total‑length setting.
- Usage Notes: Never cut or splice armored extension cable at any intermediate section; avoid sharp‑angle bending and heavy mechanical crushing damage to stainless‑steel armor; keep Mini‑Dot connector gold contacts clean and dry; inspect armor dents and connector strain‑relief status during overhaul cycles.
