Description
Bently 21747‑045‑00
- Key Features: 50‑ohm nominal impedance coaxial‑cable; PTFE insulation; dual‑end microdot male‑female connectors; non‑armored flexible outer jacket; low high‑frequency‑signal attenuation; continuous full‑length shielding braid.
- Technical Specifications & Performance Parameters
- Total cable length: 4.5 m
- Nominal impedance: 50 Ω
- Operating temperature range: ‑40 ℃ ~ +85 ℃
- Storage temperature: ‑55 ℃ ~ +125 ℃
- Weight: 0.63 kg
- Material Composition: High‑purity copper inner conductor; PTFE dielectric insulation; copper‑braided shielding net; high‑temperature‑resistant outer polymer jacket; metal microdot male‑female connector assemblies.
- Structural Features: Flexible coaxial‑cable main‑body; probe‑side microdot female‑connector; proximitor‑side microdot male‑connector; full‑run continuous shielding braid inside cable assembly.
- Working Principle: Transmit high‑frequency excitation signal output from proximitor to proximity probe, feed‑back probe coil impedance‑variation signal back to proximitor unit, preserve electrical‑loop characteristic parameters of whole eddy‑current transducer system.
- Application Scenarios: Field measuring‑points with medium‑distance wiring requirement for 7200‑series probes; petrochemical and power‑plant rotating‑machinery monitoring system; replacement for failed original extension‑cables.
- Installation Requirements: Couple female‑connector to probe integral‑cable microdot‑plug; couple male‑connector to proximitor microdot‑socket; fully tighten locking ring of microdot‑connectors; satisfy minimum‑bending‑radius requirement; separate cable routing from power‑cables; shielding braid executes single‑end grounding.
- Usage Notes: Prohibit intermediate cutting and splicing of extension‑cable; prevent mechanical squeezing and sharp‑bending damage to cable body; keep microdot‑connector pins clean and dry; sum length of probe integral‑cable and extension‑cable must conform to proximitor calibration setting.
