Description
Bently 330130‑080‑12‑05
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: 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 keeps stable dielectric performance under high‑temperature condition ‑ Stainless‑steel spiral armor provides anti‑impact, anti‑crush and anti‑abrasion mechanical protection ‑ FluidLoc sealing assembly prevents 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 ‑ Electrically interchangeable with certified 3300‑XL series transducer parts
Application Scenarios: Applied for high‑temperature zone monitoring of steam turbine, gas turbine and high‑temperature compressor in petrochemical and thermal power hazardous‑area sites. Works with Bently 3500 rack for machinery protection under high‑temperature, mechanical impact and explosive‑atmosphere conditions.
Performance Parameters: ‑ Full‑range scale factor deviation: Less than ±1% across full operating‑temperature range ‑ 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 by continuous spiral stainless‑steel armor. Both cable ends install ClickLoc coaxial connectors integrated with FluidLoc sealing parts. Armor terminates at short transition section near connectors.
Working Principle: Passive signal transmission component of eddy‑current transducer system. PFA material maintains stable dielectric property at high‑temperature environment. Armor only provides mechanical protection. FluidLoc blocks medium ingress. It keeps 75‑ohm loop impedance matching and 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 strictly forbidden ‑ Keep ≥150 mm clearance from high‑voltage power cables ‑ Tensile pulling force can only act on connector housing ‑ Connector tightening torque maximum 0.565 N·m ‑ Install external connector protector for exposed joints ‑ Total length including probe integral cable and extension cable must comply with Proximitor rated total‑length setting
Usage Notes: ‑ On‑site cutting or splicing of armored cable assembly is prohibited ‑ Operating temperature shall not exceed rated upper limit ‑ Prevent armor surface from scratch by sharp metal components ‑ Check armor integrity and FluidLoc sealing performance during shutdown maintenance ‑ Avoid long‑term contact with strong corrosive medium ‑ Complete continuity and insulation resistance test before commissioning
