Description
Bently 330130‑080‑03‑05
Technical Specifications: ‑ Cable Overall Length: 8.0 m ‑ Nominal Characteristic Impedance: 75 Ω triaxial ‑ Uniform Capacitance: 69.9 pF/m ‑ Insulation Material: FEP fluoropolymer ‑ Continuous Operating Temperature: ‑52 °C ~ +125 °C ‑ Minimum Static Bend Radius: 38.1 mm ‑ Connector Type: ClickLoc FluidLoc miniature self‑locking coaxial connector ‑ Armor Material: 304 stainless‑steel spiral armor ‑ Net Weight: 0.54 kg ‑ Agency Approval: ATEX, IECEx, CSA hazardous‑area certification ‑ Signal Bandwidth: 10 Hz‑10 kHz
Functional Features: ‑ Stainless‑steel spiral armor resists impact, crush and abrasion damage ‑ FluidLoc sealing assembly blocks oil, water and vapor entering cable inner cavity ‑ Triaxial double‑layer shielding suppresses external EMI and RFI interference ‑ Pure passive transmission, no internal power‑consuming components ‑ Electrically interchangeable with certified 3300‑XL series transducer parts ‑ Anti‑vibration ClickLoc locking connector prevents loose connection
Application Scenarios: Suitable for rotating machinery monitoring in petrochemical, refining and offshore hazardous‑area sites. Applied to steam turbine, gas turbine, centrifugal compressor and large process pump. Cooperates with Bently 3500 rack for machinery protection under mechanical damage risk and explosive atmosphere.
Performance Parameters: ‑ Full‑range scale factor deviation: Less than ±1% ‑ Humidity resistance: Stable under 93% non‑condensing relative humidity ‑ Storage Temperature: ‑55 °C ~ +135 °C ‑ DC core‑to‑core resistance: 1.18 Ω nominal ‑ Armor can bear radial crush load without permanent deformation
Material Composition: ‑ Inner conductor: tinned copper ‑ Intermediate insulation: FEP fluoropolymer ‑ Double‑layer shielding: copper braided mesh ‑ Outer jacket: FEP fluoropolymer ‑ Armor: 304 stainless‑steel spiral strip ‑ Connector shell and contact: gold‑plated beryllium copper ‑ Sealing ring: fluororubber
Structural Features: Concentric triaxial inner core, wrapped by continuous spiral stainless‑steel armor. Both cable ends install ClickLoc coaxial connectors integrated with FluidLoc sealing structure. Armor terminates at short transition section near connectors.
Working Principle: Passive signal transmission component of eddy‑current transducer system. Armor only provides mechanical protection and will not change electrical characteristics. FluidLoc prevents medium ingress. It maintains 75‑ohm loop impedance matching, transmits gap‑proportional DC voltage signal from probe to Proximitor sensor.
Installation Requirements: ‑ Follow armored‑cable minimum static bend radius 38.1 mm, sharp bending is forbidden ‑ Keep ≥150 mm clearance from high‑voltage power cables ‑ Tensile pulling force shall only act on connector housing, armor and cable core cannot bear pulling load ‑ Connector tightening torque maximum 0.565 N·m ‑ Install external connector protector for exposed joints ‑ Total length of probe integral cable plus extension cable must conform to Proximitor rated total‑length setting
Usage Notes: ‑ On‑site cutting or splicing of armored cable assembly is strictly prohibited ‑ Prevent armor surface from scratch by sharp metal edges ‑ Check armor integrity and FluidLoc sealing condition during shutdown maintenance ‑ Avoid long‑time contact with strong corrosive medium ‑ Complete continuity and insulation resistance test before commissioning
