Description
Bently 330130‑080‑12‑00
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: 25.4 mm ‑ Connector Type: ClickLoc miniature self‑locking coaxial connector ‑ Net Weight: 0.38 kg ‑ Agency Approval: General industrial high‑temperature version ‑ Signal Bandwidth: 10 Hz‑10 kHz
Functional Features: ‑ PFA high‑temperature insulation keeps stable dielectric performance under high‑temperature working condition ‑ Full triaxial shielding restrains industrial electromagnetic interference ‑ Pure passive transmission structure, no internal power‑consuming components ‑ Electrically interchangeable with standard 3300‑XL probe and Proximitor assemblies ‑ ClickLoc locking connector resists loosening under continuous mechanical vibration
Application Scenarios: Used for high‑temperature area monitoring of steam turbine, gas turbine and high‑temperature compressor. Applied in thermal power plant and petrochemical high‑temperature workshop. Matches Bently 3500 monitoring rack for rotating machinery protection.
Performance Parameters: ‑ Full‑range scale factor deviation: Less than ±1% within full 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
Material Composition: ‑ Inner conductor: tinned copper ‑ Intermediate insulation: PFA fluoropolymer ‑ Double‑layer shielding: copper braided mesh ‑ Outer jacket: PFA fluoropolymer ‑ Connector shell and contact: gold‑plated brass
Structural Features: Concentric multi‑layer triaxial cable core with PFA high‑temperature insulation, without armor layer. ClickLoc self‑locking coaxial connectors installed on both cable ends. No FluidLoc sealing assembly.
Working Principle: Passive signal transmission component for eddy‑current transducer system. PFA material guarantees stable dielectric property under high‑temperature environment. It maintains 75‑ohm loop impedance matching, transmits gap‑related DC voltage signal from proximity probe to Proximitor sensor.
Installation Requirements: ‑ Respect minimum static bend radius 25.4 mm, sharp kinks are forbidden ‑ Maintain 150 mm separation distance from high‑voltage power cables ‑ Tensile force shall only apply to connector housing ‑ Connector tightening torque maximum 0.565 N·m ‑ Equip connector protector for exposed joints ‑ Combined length of probe cable and extension cable must satisfy Proximitor total‑length requirement
Usage Notes: ‑ Field cutting and splicing of cable assembly are strictly prohibited ‑ Operating temperature shall never exceed rated upper limit value ‑ Prevent sharp objects scratching PFA outer jacket ‑ Check connector locking condition during regular maintenance ‑ Perform continuity and insulation resistance test before putting into service
