Functional Features: ‑ Coaxial shielding restrains external industrial EMI and RFI signal interference ‑ Pure passive transmission structure, no internal electronic consuming parts ‑ Fully electrically interchangeable with standard 3300 XL NSv probes and Proximitor assemblies ‑ ClickLoc anti‑loose locking connector adapts to long‑term machine vibration operating environment ‑ Stable capacitance and impedance parameters in full rated working‑temperature range
Application Scenarios: Applied for compact centrifugal compressors, turbo‑expanders, process pumps and high‑speed blowers in thermal power plants and ordinary petrochemical workshops. Matches Bently 3500 monitoring rack for rotating machinery protection, suitable for cable routes with sufficient routing protection without crush risk.
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
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: Multi‑layer concentric coaxial cable core without metal armor layer. ClickLoc self‑locking coaxial connectors are mounted on both cable ends. FluidLoc sealing assembly is not equipped.
Working Principle: Passive signal transmission unit belonging to NSv eddy‑current transducer system. It maintains 75‑ohm measuring‑loop impedance matching. Gap‑related DC voltage signal generated by proximity probe transmits through coaxial cable to NSv Proximitor sensor, preserves linear gap‑voltage response for accurate displacement and vibration measurement.
Installation Requirements: ‑ Observe minimum static bend radius 25.4 mm, sharp kinks and acute folding are prohibited ‑ Keep minimum 150 mm clearance from high‑voltage power cables ‑ Tensile load shall only apply on connector housing ‑ Connector tightening torque maximum 0.565 N·m ‑ Install external connector protector for exposed joints ‑ Total length of probe integral cable plus extension cable must comply with NSv Proximitor total‑length configuration parameter
Usage Notes: ‑ Field cutting and splicing of cable assembly are strictly forbidden ‑ Prevent sharp objects scratching FEP outer jacket surface ‑ Avoid long‑time direct contact with high‑temperature equipment surfaces ‑ Check connector locking condition during periodic maintenance ‑ Execute continuity and insulation resistance test before system putting‑into‑service
