Description
Bently 330930‑060‑01‑00
Technical Specifications: ‑ Cable Overall Length: 6.0 m ‑ Nominal Characteristic Impedance: 75 Ω coaxial ‑ Uniform Capacitance: 69.9 pF/m ‑ Insulation Material: FEP fluoropolymer ‑ Continuous Operating Temperature: ‑52 °C ~ +177 °C ‑ Minimum Static Bend Radius: 38.1 mm ‑ Connector Type: ClickLoc miniature self‑locking coaxial connector ‑ Armor Material: AISI 302 stainless‑steel spiral armor ‑ Net Weight: 0.49 kg ‑ Agency Approval: General industrial grade, no hazardous‑area certification ‑ Signal Bandwidth: 0 Hz‑10 kHz
Functional Features: ‑ Stainless‑steel spiral armor resists mechanical impact, squeezing and surface abrasion during installation and long‑term field operation ‑ Coaxial shielding suppresses industrial EMI and RFI interference signals ‑ Pure passive transmission assembly without internal power‑consuming electronic components ‑ Electrically interchangeable with all certified 3300 XL NSv probes and Proximitor sensors ‑ Anti‑vibration ClickLoc locking connector prevents loose connection under sustained machine vibration ‑ Consistent electrical performance within full rated operating‑temperature scope
Application Scenarios: Used for compact centrifugal compressors, turbo‑expanders, high‑speed process pumps and blowers inside petrochemical workshops and thermal power plants. Works with Bently 3500 monitoring rack for machinery protection, applicable for cable paths subject to mechanical collision and abrasion hazards.
Performance Parameters: ‑ Full‑range scale factor deviation: Less than ±1% ‑ Humidity resistance: Stable under 100% non‑condensing relative humidity ‑ Storage Temperature: ‑52 °C ~ +177 °C ‑ DC core‑to‑core resistance: 1.08 Ω nominal ‑ Armor withstands rated radial crush load without permanent deformation
Material Composition: ‑ Inner conductor: tinned copper ‑ Intermediate insulation: FEP fluoropolymer ‑ Single‑layer shielding: copper braided mesh ‑ Outer jacket: FEP fluoropolymer ‑ Armor: AISI 302 stainless‑steel spiral strip ‑ Connector shell and contact: gold‑plated brass ‑ Sealing ring: fluororubber
Structural Features: Concentric coaxial inner core wrapped with continuous spiral stainless‑steel armor. ClickLoc miniature self‑locking coaxial connectors are installed on both cable ends. Armor terminates at short transition section adjacent to connectors. FluidLoc sealing structure is not fitted for this model.
Working Principle: Passive signal transmission component for NSv eddy‑current transducer system. Armor delivers mechanical protection only without changing electrical properties. It maintains strict 75‑ohm loop impedance matching. Displacement‑proportional DC voltage signal output from proximity probe transmits through coaxial cable to NSv Proximitor sensor, guarantees linear gap‑voltage measurement response.
Installation Requirements: ‑ Comply with armored‑cable minimum static bend radius 38.1 mm, sharp bending is strictly forbidden ‑ Maintain minimum 150 mm separation distance from high‑voltage power cables ‑ Tensile pulling force shall only apply on connector housing, armor and cable core cannot sustain pulling load ‑ Connector tightening torque maximum 0.565 N·m ‑ Fit external connector protector for exposed connection joints ‑ Combined length of probe built‑in cable and extension cable must satisfy NSv Proximitor total‑length setting
Usage Notes: ‑ On‑site cutting or splicing of armored cable assembly is strictly prohibited ‑ Prevent armor outer surface from scratch caused by sharp metal edges ‑ Inspect armor integrity and connector locking state during scheduled shutdown maintenance ‑ Avoid long‑time direct contact with strong corrosive chemical medium ‑ Complete continuity test and insulation resistance test before system commissioning
