Description
Bently 330130‑080‑13‑05
Technical Specifications: ‑ Cable Overall Length: 8.0 m ‑ Nominal Characteristic Impedance: 75 Ω triaxial ‑ Uniform Capacitance: 69.9 pF/m ‑ Insulation Material: PFA fluoropolymer ‑ Continuous Operating Temperature: ‑55 °C ~ +177 °C ‑ Minimum Static Bend Radius: 38.1 mm ‑ Connector Type: Special‑variant ClickLoc FluidLoc miniature self‑locking coaxial connector ‑ Armor Material: 304 stainless‑steel spiral armor ‑ Net Weight: 0.56 kg ‑ Agency Approval: ATEX, IECEx, CSA hazardous‑area certification ‑ Signal Bandwidth: 10 Hz‑10 kHz
Functional Features: ‑ PFA high‑temperature insulation guarantees stable dielectric performance in high‑temperature environment ‑ Stainless‑steel spiral armor resists impact, crush and abrasion damage ‑ Special‑variant ClickLoc connector adapts to limited‑space special‑layout installation ‑ FluidLoc sealing assembly blocks oil mist, water and vapor penetrating into cable inner cavity ‑ Triaxial double‑layer shielding suppresses external EMI and RFI interference ‑ Pure passive transmission, no internal power‑consuming components ‑ Matches special‑configuration 3300‑XL probes and Proximitor sensors
Application Scenarios: Used for special‑layout high‑temperature monitoring points of steam turbine, gas turbine and high‑temperature compressor in petrochemical and thermal power hazardous‑area sites. Cooperates with Bently 3500 rack for rotating machinery protection.
Performance Parameters: ‑ Full‑range scale factor deviation: Less than ±1% within full operating‑temperature scope ‑ Humidity resistance: Stable under 93% non‑condensing relative humidity ‑ Storage Temperature: ‑55 °C ~ +185 °C ‑ DC core‑to‑core resistance: 1.18 Ω nominal ‑ Armor bears radial crush load without permanent deformation
Material Composition: ‑ Inner conductor: tinned copper ‑ Intermediate insulation: PFA fluoropolymer ‑ Double‑layer shielding: copper braided mesh ‑ Outer jacket: PFA fluoropolymer ‑ Armor: 304 stainless‑steel spiral strip ‑ Connector shell and contact: gold‑plated beryllium copper ‑ Sealing ring: fluororubber
Structural Features: Concentric triaxial inner core with PFA high‑temperature insulation, outer wrapped with continuous spiral stainless‑steel armor. Both cable ends install special‑variant ClickLoc coaxial connectors integrated with FluidLoc sealing assembly. Armor terminates at short transition section near connectors.
Working Principle: Passive signal transmission component for eddy‑current transducer system. PFA material maintains stable dielectric property at high‑temperature working condition. Armor provides mechanical protection only. FluidLoc prevents medium ingress. It keeps 75‑ohm loop impedance matching and transmits gap‑proportional DC voltage signal from proximity probe to Proximitor sensor.
Installation Requirements: ‑ Follow armored‑cable minimum static bend radius 38.1 mm, sharp bending is forbidden ‑ Maintain ≥150 mm clearance from high‑voltage power cables ‑ Tensile pulling force shall only act on connector housing ‑ Connector tightening torque maximum 0.565 N·m ‑ Adopt matched special‑variant connector protector for exposed joints ‑ Total length including probe integral cable and extension cable must conform to Proximitor rated total‑length setting
Usage Notes: ‑ On‑site cutting or splicing of armored cable assembly is strictly prohibited ‑ Operating temperature shall not exceed rated upper limit ‑ Prevent armor surface from scratch by sharp metal edges ‑ Check armor integrity, connector locking state and FluidLoc sealing performance during shutdown maintenance ‑ Avoid long‑time contact with strong corrosive medium ‑ Complete continuity and insulation resistance test before commissioning
