Bently 130120‑0025‑02

Product Introduction: 130120‑0025‑02 is armored‑version factory‑calibrated NSv extension‑cable with physical length 2.5 meters. It is designed for severe industrial sites where cable faces mechanical‑abrasion, impact, animal‑bite risk or heavy‑vibration environment. It inherits full electrical‑calibration specification of NSv extension‑cable series and adds continuous metallic armor outer protective layer. It matches 3300 NSv proximity‑probe and 990 / 991 integrated transmitters, used to extend eddy‑current‑sensor signal transmission distance in harsh field installation‑conditions.

  • Weight: 0.34 kg Functional Features:
  1. Factory‑pre‑calibrated electrical‑length and impedance parameter, guarantee NSv transducer‑system measurement linearity.
  2. Continuous stainless‑steel spiral armor provides strong mechanical‑protection against impact, abrasion, crushing and rodent‑bite damage.
  3. Internal double‑layer copper‑braid shielding suppresses industrial‑site electromagnetic interference for low‑level high‑frequency eddy‑current‑sensor signals.
  4. FEP inner‑cable insulation offers excellent resistance against high‑temperature, machine‑oil and chemical solvent corrosion.
  5. Both‑ends pre‑assembled NSv dedicated coaxial‑connectors maintain full‑system electrical‑performance, no on‑site connector assembly work required.
  6. Suitable for exposed field‑cable‑routing without additional heavy‑metal conduit protection in many installation scenarios. Application Scenarios: NSv proximity‑probe signal extension for exposed cable‑routing on compressor casings, turbine bases; petrochemical‑plant harsh‑environment machinery‑monitoring points; field locations with high mechanical‑damage risk; outdoor exposed instrument‑cable routing for rotating‑equipment monitoring systems. Performance Parameters: Consistent impedance and electrical‑length same‑series specification; low high‑frequency‑signal attenuation; stable electrical‑performance under repeated mechanical‑bending and vibration cycles. Material Composition: Central solid copper signal conductor; FEP inner insulation; double‑layer copper‑braid shielding; inner FEP jacket; continuous spiral‑wound stainless‑steel armor layer; outer protective wrapping layer; nickel‑plated brass NSv coaxial connectors; high‑temperature‑resistant sealing gaskets. Structural Characteristics: Armored flexible coaxial‑cable structure; stainless‑steel spiral armor wraps full‑cable length; both‑ends pre‑installed NSv miniature coaxial‑connectors; cable surface printed with full part‑number, length marking and unique factory serial‑number. Armor terminates properly at connector‑strain‑relief section to avoid armor sharp‑edge cutting inner cable assembly. Working Principle: Identical electrical‑signal‑transmission principle as non‑armored NSv extension‑cable. Inner calibrated coaxial‑cable transmits high‑frequency excitation signal and return impedance‑variation signal between NSv probe and 990 / 991 transmitter. Outer stainless‑steel armor layer purely implements mechanical‑protection function and does not participate in signal transmission. Total electrical‑length of probe plus extension‑cable must match transmitter calibrated system‑length setting. Installation Requirements:
  7. Observe larger minimum‑bending radius due to armor structure; never force sharp bending which will permanently deform stainless‑steel spiral armor and damage inner coaxial‑cable.
  8. Route armored cable separately away from high‑power drive cables to prevent electromagnetic‑noise coupling.
  9. Tighten coaxial‑connectors only via knurled nut by specified hand‑torque; avoid wrench force applied to armor or cable‑body.
  10. Install proper strain‑relief fixation near both‑end connectors, prevent cable weight and equipment‑vibration force transferring directly onto connector assemblies.
  11. Sum total electrical‑length of NSv probe plus this armored extension‑cable, ensure matches 990 / 991 transmitter factory‑calibrated total‑system‑length parameter. Usage Notes:
  12. Forbid cutting, splicing or re‑terminating armored cable body. Cutting destroys factory‑calibrated electrical‑length and impedance and voids system‑calibration.
  13. Prevent armor sharp‑edge from abrading adjacent cables or equipment surfaces during installation and operation.
  14. Do not perform high‑voltage megger test across signal conductors of this cable.
  15. Regularly inspect armor surface for crack or breakage signs during equipment overhaul; broken armor exposes inner coaxial‑cable to mechanical‑damage risk.
  16. This armored cable cannot be replaced with non‑calibrated general armored coaxial‑cable.
