Description
Bently 330930‑045‑00‑05
Technical Specifications: ‑ Cable Overall Length: 4.5 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: 25.4 mm ‑ Connector Type: ClickLoc miniature self‑locking coaxial connector ‑ Net Weight: 0.31 kg ‑ Agency Approval: ATEX, IECEx, CSA hazardous‑area certification ‑ Signal Bandwidth: 0 Hz‑10 kHz
Functional Features: ‑ Certified construction satisfies international hazardous‑area installation standards ‑ Coaxial shielding suppresses EMI and RFI interference from surrounding high‑power industrial equipment ‑ Pure passive transmission assembly without internal power‑consuming electronic elements ‑ Electrically interchangeable with all qualified 3300 XL NSv probes and Proximitor sensors ‑ Vibration‑resistant ClickLoc locking connector prevents connection loosening under continuous machine operation ‑ Stable capacitance and impedance performance across full operating‑temperature range
Application Scenarios: Used for compact rotating machinery monitoring inside petrochemical refining plants, offshore platforms and natural‑gas processing facilities with explosive classified zones. Target equipment includes small centrifugal compressors, turbo‑expanders and process pumps. Works cooperatively with Bently 3500 monitoring rack for hazardous‑area machinery protection function.
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: 0.81 Ω nominal
Material Composition: ‑ Inner conductor: tinned copper ‑ Intermediate insulation: FEP fluoropolymer ‑ Single‑layer shielding: copper braided mesh ‑ Outer jacket: FEP fluoropolymer ‑ Connector shell and contact: gold‑plated brass
Structural Features: Concentric multi‑layer coaxial cable core without metal armor. Both cable ends fitted with ClickLoc self‑locking coaxial connectors. No FluidLoc sealing assembly equipped for this part number.
Working Principle: Passive signal transmission component of NSv eddy‑current transducer system. It keeps 75‑ohm loop impedance matching. Displacement‑related DC voltage signal output from proximity probe transmits through coaxial cable to NSv Proximitor sensor, preserves linear gap‑voltage response for accurate vibration and displacement measurement.
Installation Requirements: ‑ Observe minimum static bend radius 25.4 mm, sharp kinks are forbidden ‑ Maintain minimum 150 mm separation distance from high‑voltage power cables ‑ Tensile pulling force shall only apply to connector housing ‑ Connector tightening torque maximum 0.565 N·m ‑ Fit connector protector for exposed connection joints ‑ Total length combining probe integral cable and extension cable must comply with NSv Proximitor total‑length setting ‑ All field installation must strictly follow local hazardous‑area wiring regulations
Usage Notes: ‑ On‑site cutting and splicing of cable assembly are strictly prohibited ‑ Avoid sharp objects scratching FEP outer jacket ‑ Prevent long‑time contact with high‑temperature equipment surfaces ‑ Inspect connector locking condition during scheduled shutdown maintenance ‑ Complete continuity and insulation resistance test before system commissioning in hazardous zones
