Description
Bently 330130‑085‑00‑05
- Key Features: 75‑ohm nominal triaxial impedance; FEP high‑temperature insulation; FluidLoc liquid‑blocking internal barrier; dual‑end Mini‑Dot male‑female connectors; low high‑frequency‑signal attenuation; full compatibility with all standard 3300‑XL probes and proximitors; no external power consumption.
- Technical Specifications & Performance Parameters
- Total cable length: 8.5 m
- Nominal impedance: 75 Ω triaxial
- Operating temperature range: ‑51 ℃ ~ +177 ℃
- Storage temperature: ‑55 ℃ ~ +180 ℃
- Weight: 0.92 kg
- Connector type: Mini‑Dot male‑female gold‑plated brass connectors
- Material Composition: High‑purity copper inner conductor; FEP fluoropolymer dielectric insulation; FluidLoc internal liquid‑blocking barrier layer; multi‑layer copper triaxial shielding network; high‑temperature‑resistant outer polymer jacket; gold‑plated brass Mini‑Dot male‑female connector assemblies at both cable ends.
- Structural Features: Flexible circular triaxial cable main‑body; probe‑side Mini‑Dot female connector; proximitor‑side Mini‑Dot male connector; FluidLoc barrier integrated inside cable dielectric structure; continuous multi‑layer shielding runs through full cable length; compact strain‑relief structure at cable‑connector transition sections.
- Working Principle: This cable acts as high‑frequency signal transmission medium within eddy‑current transducer chain. It forwards proximitor‑generated high‑frequency excitation signal to field‑installed proximity probe, and feeds back probe‑coil impedance‑variation signal back to proximitor unit. FluidLoc barrier stops oil and liquid migration along cable internal layers. It maintains stable 75‑ohm triaxial impedance for entire measurement circuit.
- Application Scenarios: Long‑distance wiring for 3300‑XL proximity‑probe measuring‑points; turbine and compressor bearing‑housing sites with heavy oil‑mist environment; petrochemical plant TSI monitoring cabinets; spare‑part replacement for FluidLoc‑configured legacy 3300‑XL transducer systems.
- Installation Requirements: Couple female Mini‑Dot connector to probe‑integral‑cable plug; connect male Mini‑Dot connector to proximitor socket; tighten locking ring of Mini‑Dot connectors completely; satisfy minimum bending‑radius requirement for triaxial cable; lay extension cable inside separate cable‑tray isolated from high‑power‑cable routes; implement single‑end grounding for cable shielding layers; sum length of probe integral‑cable plus extension‑cable must match proximitor total‑length configuration.
- Usage Notes: Intermediate cutting and field‑splicing of extension cable is strictly prohibited; avoid mechanical squeezing, crushing and sharp‑angle bending damage to cable jacket; keep Mini‑Dot connector gold contacts clean from oil, dust and moisture contamination; never remove factory‑installed strain‑relief components at cable‑connector junctions.
