Bently 330130‑070‑01‑0
Technical Specifications: ‑ Cable Overall Length: 7.0 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: 38.1 mm ‑ Connector Type: ClickLoc miniature self‑locking coaxial connector ‑ Armor Material: 304 stainless‑steel spiral armor ‑ Net Weight: 0.48 kg ‑ Agency Approval: No hazardous‑area certification ‑ Signal Bandwidth: 10 Hz‑10 kHz
Functional Features: ‑ Integrated stainless‑steel spiral armor resists mechanical impact, squeezing and surface abrasion during installation and long‑term operation ‑ Full triaxial shielding structure suppresses industrial EMI and RFI interference, eliminates signal crosstalk ‑ Pure passive signal transmission structure, no internal power‑consuming components, no signal amplification or attenuation ‑ Electrically interchangeable with all qualified 3300‑XL series probes and Proximitor sensors, no extra field calibration required after replacement ‑ Gold‑plated ClickLoc locking connectors realize stable quick connection, anti‑loosening performance under continuous mechanical vibration ‑ Consistent electrical parameters within full operating temperature range, zero impedance drift
Application Scenarios: Applied for vibration amplitude, axial position and Keyphasor phase‑speed measurement of steam turbines, gas turbines, centrifugal compressors, large process pumps and induced draft fans. Deployed in petrochemical, thermal power, oil‑gas processing industries. Matches with Bently 3500 monitor rack to realize real‑time machinery protection and fault early warning, suitable for field positions where cables face mechanical damage risks.
Performance Parameters: ‑ Full‑range scale factor deviation: Less than ±1% ‑ Humidity resistance: Stable operation under 93% non‑condensing relative humidity ‑ Storage Temperature: ‑55 °C ~ +185 °C ‑ DC core‑to‑core resistance: 1.15 Ω nominal ‑ Armor withstand radial crush load without permanent deformation
Material Composition: ‑ Inner conductor: tinned copper ‑ Intermediate insulation: FEP fluoropolymer ‑ Double‑layer shielding: copper braided mesh ‑ Outer jacket: FEP fluoropolymer ‑ Armor: 304 stainless‑steel spiral strip ‑ Connector shell and contact: gold‑plated brass ‑ Sealing ring: fluororubber
Structural Features: Multi‑layer triaxial inner core construction, outer wrapped with continuous spiral stainless‑steel armor. Both cable ends install ClickLoc miniature self‑locking coaxial connectors. Armor section stops at short transition zone near connectors. No FluidLoc sealing structure on this model.
Working Principle: Belongs to passive signal transmission component of eddy‑current transducer system. Armor only provides mechanical protection without modifying electrical characteristics. It keeps 75‑ohm loop impedance matching. Gap‑related DC voltage signal output from proximity probe transmits through triaxial cable to Proximitor sensor, maintains linear voltage‑gap response for displacement and vibration measurement.
Installation Requirements: ‑ Follow armored‑cable minimum bend radius 38.1 mm, forbid sharp kinks and acute folding ‑ Keep ≥150 mm separation distance from high‑voltage power cables and motor power lines ‑ Tensile pulling force shall only apply on connector housing, never pull cable body or armor ‑ ClickLoc connector tightening torque maximum 0.565 N·m, over‑torque is forbidden ‑ Install external connector protector for exposed joint positions ‑ Sum of probe built‑in cable length plus this extension cable length must match rated total‑length setting of matched Proximitor sensor
Usage Notes: ‑ On‑site cutting, stripping or splicing of armored cable is strictly prohibited ‑ Prevent sharp edges scratching stainless‑steel armor surface ‑ Check armor integrity and connector locking status during regular equipment maintenance ‑ Avoid long‑time direct contact with strong corrosive medium ‑ Complete continuity test and insulation resistance test before system commissioning
