Description
Bently 330130‑085‑00‑01
Technical Specifications: ‑ Cable Overall Length: 8.5 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: 0.39 kg ‑ Agency Approval: General industrial grade ‑ Signal Bandwidth: 10 Hz‑10 kHz
Functional Features: ‑ Full triaxial shielding restrains industrial electromagnetic interference ‑ Pure passive transmission structure, no internal power‑consuming components ‑ Electrically interchangeable with standard 3300‑XL probes and Proximitor sensors ‑ ClickLoc anti‑loose connector adapts to long‑term machine vibration environment ‑ Electrical parameters keep stable within full rated working temperature range
Application Scenarios: Applied for vibration and displacement monitoring of steam turbine, gas turbine, centrifugal compressor, process pump and large‑size fan. Deployed in thermal power plant and ordinary petrochemical workshop. Matches Bently 3500 monitoring rack for rotating machinery protection.
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: 1.24 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 without armor layer. ClickLoc self‑locking coaxial connectors installed on both cable ends. No FluidLoc sealing assembly.
Working Principle: Passive signal transmission component of eddy‑current transducer system. It maintains 75‑ohm loop impedance matching. Transmits gap‑proportional DC voltage signal output from proximity probe to Proximitor sensor, guarantees linear measurement response for displacement and vibration.
Installation Requirements: ‑ Observe minimum static bend radius 25.4 mm, sharp kinks are prohibited ‑ Keep 150 mm minimum separation distance from high‑voltage power cables ‑ Tensile pulling force shall only bear on connector housing ‑ Connector tightening torque maximum 0.565 N·m ‑ Install connector protector for exposed connection joints ‑ Combined length of probe integral cable and extension cable must satisfy Proximitor total‑length setting
Usage Notes: ‑ Field cutting and splicing of cable assembly are strictly forbidden ‑ Prevent outer FEP jacket from scratch by sharp components ‑ Avoid direct long‑time contact with high‑temperature surfaces ‑ Inspect connector locking condition during periodic maintenance ‑ Perform continuity and insulation resistance test before system commissioning
