Description
Bently 3301‑30‑08‑00‑002
Technical Specifications: ‑ Cable Overall Length: 8.0 m ‑ Nominal Characteristic Impedance: 75 Ω triaxial ‑ Uniform Capacitance: 69.9 pF/m ‑ Insulation Material: FEP fluoropolymer ‑ Continuous Operating Temperature: ‑52 °C ~ +125 °C ‑ Minimum Static Bend Radius: 25.4 mm ‑ Connector Type: ClickLoc miniature self‑locking coaxial connector ‑ Net Weight: 0.36 kg ‑ Agency Approval: General industrial version, no explosion‑proof certification ‑ Signal Bandwidth: 10 Hz‑10 kHz
Functional Features: ‑ Triaxial shielding structure restrains external electromagnetic interference ‑ Passive transmission design, no built‑in electronic components ‑ Compatible with standard 3300‑XL series probes and Proximitor sensors ‑ ClickLoc anti‑loose connector adapts to long‑term vibration environment ‑ Electrical parameters remain stable within rated working temperature range
Application Scenarios: Suitable for vibration and displacement monitoring of steam turbine, gas turbine, centrifugal compressor, large‑size fan and process pump. Applied in thermal power plant, general petrochemical workshop without hazardous‑area requirement. Cooperates with Bently 3500 rack for machinery protection function.
Performance Parameters: ‑ Full‑range scale factor deviation: Less than ±1% ‑ Humidity resistance: Stable under 93% non‑condensing relative humidity ‑ Storage Temperature: ‑55 °C ~ +135 °C ‑ DC core‑to‑core resistance: 1.18 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
Structural Features: Concentric multi‑layer triaxial cable core, no armor layer. Two ends fitted with ClickLoc self‑locking coaxial connectors. No FluidLoc sealing assembly for this part number.
Working Principle: Passive signal transmission component for eddy‑current transducer system. Maintains 75‑ohm loop impedance matching. Transmits gap‑proportional DC voltage signal from probe to Proximitor sensor, guarantees linear measurement output.
Installation Requirements: ‑ Minimum static bend radius 25.4 mm, sharp folding is not allowed ‑ Separate laying route from high‑power cables, maintain 150 mm minimum clearance ‑ Pulling force shall act only on connector housing ‑ Connector tightening torque maximum 0.565 N·m ‑ Install connector protector for exposed joints ‑ Sum of probe cable and extension cable length shall match Proximitor total‑length setting
Usage Notes: ‑ Field cutting and splicing of cable assembly are prohibited ‑ Avoid scratch and abrasion on outer FEP jacket ‑ Keep away from over‑heated equipment surfaces ‑ Check connector locking state during periodic maintenance ‑ Perform continuity and insulation resistance test before commissioning
