Description
Bently 330190‑045‑00‑00
- Key Features: 75‑ohm nominal triaxial impedance; FEP high‑temperature dielectric insulation; full‑length stainless‑steel flexible armor; dual‑end Mini‑Dot male‑female gold‑plated connectors; controlled low high‑frequency‑signal attenuation; strong anti‑abrasion and anti‑crushing mechanical performance; full compatibility with all standard 3300‑XL probes and proximitor modules.
- Technical Specifications & Performance Parameters
- Total cable length: 4.5 m
- Nominal impedance: 75 Ω triaxial
- Operating temperature range: ‑51 ℃ ~ +177 ℃
- Storage temperature: ‑55 ℃ ~ +180 ℃
- Weight: 0.79 kg
- 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 terminals.
- Structural Features: Flexible triaxial cable main‑body wrapped by continuous stainless‑steel armor braid; probe‑side Mini‑Dot female connector; proximitor‑side Mini‑Dot male connector; reinforced strain‑relief structures at cable‑connector transition sections; multi‑layer shielding runs through full cable length.
- Working Principle: This armored triaxial cable delivers high‑frequency excitation signal from proximitor to field proximity probe, and returns probe‑coil impedance‑variation feedback signal back to proximitor unit. Stainless‑steel armor bears external mechanical impact and abrasion load, protecting inner triaxial signal structure. Cable maintains stable 75‑ohm triaxial impedance for complete eddy‑current measurement circuit.
- Application Scenarios: Medium‑distance wiring for 3300‑XL transducer chains under high‑mechanical‑stress environment; power‑plant and petrochemical rotating‑machinery TSI systems; spare‑part replacement for original armored 4.5‑meter extension‑cable assemblies.
- Installation Requirements: Couple female Mini‑Dot connector to probe‑integral‑cable plug; couple male Mini‑Dot connector to proximitor socket; fully fasten Mini‑Dot locking ring; strictly follow minimum bending‑radius requirement for armored cable assembly; lay armored cable inside dedicated cable‑tray isolated from high‑power‑cable routes; implement single‑end grounding for cable shielding layers; total sum length of probe integral‑cable and extension‑cable must satisfy proximitor factory‑calibration parameter.
- Usage Notes: Intermediate cutting and field‑splicing of armored extension cable is strictly forbidden; prevent sharp‑bending and mechanical crushing damage to stainless‑steel armor braid; keep Mini‑Dot connector gold contacts free from oil, dust and moisture contamination; inspect armor deformation and strain‑relief integrity during regular equipment overhaul.
