Description
Bently 330130‑075‑00‑05
Technical Specifications: ‑ Cable Overall Length: 7.5 m ‑ Nominal Characteristic Impedance: 75 Ω triaxial ‑ 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 FluidLoc miniature self‑locking coaxial connector ‑ Net Weight: 0.34 kg ‑ Agency Approval: ATEX, IECEx, CSA hazardous‑area certification ‑ Signal Bandwidth: 10 Hz‑10 kHz
Functional Features: ‑ Built‑in FluidLoc sealing assembly prevents oil, water and vapor ingress into internal conductor cavity ‑ Full triaxial shielding suppresses EMI and RFI interference from surrounding high‑power equipment ‑ Pure passive component, no power consumption inside cable assembly ‑ Fully electrically interchangeable with standard 3300‑XL probe and Proximitor units ‑ Vibration‑resistant ClickLoc locking connector prevents loose connection under continuous machine vibration ‑ Stable capacitance and impedance across full working temperature scope
Application Scenarios: Used for shaft vibration, thrust displacement and Keyphasor phase speed measurement of steam turbine, gas turbine, centrifugal compressor, process pump. Widely used in petrochemical, refining, thermal power and offshore facilities. Works cooperatively with Bently 3500 monitoring rack for machinery protection in hazardous classified areas.
Performance Parameters: ‑ Full‑range scale factor deviation: Less than ±1% ‑ Humidity resistance: Stable performance under 93% non‑condensing relative humidity ‑ Storage Temperature: ‑55 °C ~ +185 °C ‑ DC core‑to‑core resistance: 1.08 Ω nominal
Material Composition: ‑ Inner conductor: tinned copper ‑ Intermediate insulation: FEP fluoropolymer ‑ Double‑layer shielding: copper braided mesh ‑ Outer jacket: FEP fluoropolymer ‑ Connector shell and contact: gold‑plated brass ‑ Sealing components: fluororubber
Structural Features: Multi‑layer triaxial cable core without metal armor. Both cable ends are equipped with ClickLoc coaxial connectors integrated with FluidLoc sealing parts. Layer‑by‑layer concentric structure ensures stable impedance characteristics.
Working Principle: Passive signal transmission part for eddy‑current transducer system. The cable maintains fixed 75‑ohm loop impedance. Displacement‑related DC voltage signal generated by proximity probe is transmitted to Proximitor sensor, preserving linear gap‑voltage relationship for accurate measurement.
Installation Requirements: ‑ Respect minimum static bend radius 25.4 mm, sharp bends are prohibited ‑ Keep at least 150 mm clearance from high‑voltage power cables ‑ Tensile force can only act on connector housing, cable jacket shall not bear pulling load ‑ Connector tightening torque shall not exceed 0.565 N·m ‑ Fit connector protector for exposed connection joints ‑ Total system length including probe integral cable and extension cable must conform to Proximitor specification
Usage Notes: ‑ Cable cutting and field splicing are strictly forbidden ‑ Avoid contact with sharp metal edges and high‑temperature surfaces ‑ Inspect FluidLoc sealing condition during routine shutdown maintenance ‑ Do not apply chemical solvents which erode FEP material ‑ Execute continuity and insulation resistance test before system start‑up
