Bently 330930‑06‑01‑00
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: ‑ Continuous stainless‑steel spiral armor absorbs external mechanical impact and resists cable crushing damage ‑ Coaxial shielding architecture suppresses industrial EMI and RFI signal crosstalk ‑ Pure passive transmission assembly with zero internal power‑consuming elements ‑ Fully interchangeable with certified 3300 XL NSv probes and Proximitor sensor units ‑ Gold‑plated ClickLoc locking connectors guarantee stable connection under sustained machine vibration ‑ Consistent capacitance and impedance values across full rated operating‑temperature scope
Application Scenarios: Designed for compact centrifugal compressors, turbo‑expanders, process pumps and high‑speed fans. Deployed in petrochemical workshops and thermal power generation plants. Cooperates with Bently 3500 monitoring rack for real‑time machinery protection, suitable for field positions where cable faces frequent mechanical contact risks.
Performance Parameters: ‑ Full‑range scale factor deviation: Less than ±1% ‑ Humidity resistance: Stable operation under 100% non‑condensing relative humidity ‑ Storage Temperature: ‑52 °C ~ +177 °C ‑ DC core‑to‑core resistance: 1.08 Ω nominal ‑ Armor withstands specified 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 construction, outer wrapped with continuous spiral stainless‑steel armor. Both cable ends install ClickLoc miniature self‑locking coaxial connectors. Armor terminates at short transition zone adjacent to connectors. FluidLoc sealing assembly is not equipped for this part number.
Working Principle: Functions as passive signal transmission component for NSv eddy‑current transducer system. Armor only provides mechanical protection without altering electrical characteristics. 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, preserves linear gap‑voltage response for displacement and vibration measurement.
Installation Requirements: ‑ Observe armored‑cable minimum static bend radius 38.1 mm, sharp kinks and acute folding are strictly forbidden ‑ Maintain minimum 150 mm separation distance from high‑voltage power cables and motor power wiring ‑ Tensile pulling force shall only apply on connector housing, never pull cable body or armor layer ‑ ClickLoc connector tightening torque maximum 0.565 N·m, over‑torque will damage internal contact structure ‑ Fit external connector protector for exposed joint positions ‑ Sum of probe built‑in cable length plus this extension cable length must match total‑length parameter setting of matched NSv Proximitor sensor
Usage Notes: ‑ On‑site cutting, stripping or splicing of armored cable assembly is strictly prohibited ‑ Prevent sharp metal edges scratching stainless‑steel armor outer surface ‑ Inspect armor integrity and connector locking condition during regular equipment shutdown maintenance ‑ Avoid long‑time direct contact with strong corrosive chemical medium ‑ Complete continuity test and insulation resistance test before system commissioning
