Description
Bently 21747‑080‑00
- Key Features: 50‑ohm nominal impedance coaxial‑structure; PTFE high‑temperature insulation; dual‑end microdot male‑female connectors; non‑armored flexible outer jacket; controlled low‑signal attenuation over full length; continuous full‑length shielding braid.
- Technical Specifications & Performance Parameters
- Total cable length: 8.0 m
- Nominal impedance: 50 Ω
- Operating temperature range: ‑40 ℃ ~ +85 ℃
- Storage temperature: ‑55 ℃ ~ +125 ℃
- Weight: 0.82 kg
- Material Composition: High‑purity copper inner conductor; PTFE dielectric insulation layer; copper‑braided shielding layer; high‑temperature‑resistant outer polymer jacket; metal microdot male‑female connector assemblies at two terminals.
- Structural Features: Long‑length flexible coaxial‑cable body; probe‑end microdot female‑connector; proximitor‑end microdot male‑connector; continuous shielding braid running through complete cable length.
- Working Principle: Deliver high‑frequency excitation signal from proximitor unit to field‑mounted proximity probe; transmit probe coil impedance‑variation signal back to proximitor; maintain the complete electrical‑loop characteristics of the whole eddy‑current measuring‑system.
- Application Scenarios: Long‑distance wiring condition for field measuring‑points of 7200‑series proximity probes; large‑size power‑plant and petrochemical‑plant rotating‑machinery monitoring cabinets; spare‑part replacement for original long‑length extension‑cables.
- Installation Requirements: Connect female‑microdot‑connector terminal to probe integral‑cable plug; connect male‑microdot‑connector terminal to proximitor socket; fully lock microdot‑connector locking‑ring; strictly follow minimum‑bending‑radius requirement; lay extension‑cable in separate cable‑tray isolated from high‑power‑cables; implement single‑end grounding for shielding braid.
- Usage Notes: Intermediate cutting and splicing of extension‑cable is strictly forbidden; avoid sharp‑bending and mechanical crushing damage on cable body; keep microdot‑connector contact‑pins free from moisture, dust and grease pollution; total sum length of probe integral‑cable plus extension‑cable must satisfy factory‑calibrated parameter of matched proximitor unit.
