Technical Specifications Precision impedance‑controlled coaxial shielded cable. Operating temperature range ‑40℃ ~ +125℃. Double‑layer shielding structure for anti‑electromagnetic interference. Equipped with Bently‑dedicated precision crimp connectors at both ends. Outer sheath features oil‑resistant, anti‑aging and high‑temperature resistant performance. Must be used as complete set together with matched probe and proximitor unit.
Functional Features Transmit high‑frequency gap voltage signal output by proximity probe to proximitor preamplifier. Strict characteristic impedance control ensures signal transmission integrity. Double‑layer shielding suppresses external electromagnetic field interference. Special‑purpose connectors maintain stable connection performance under mechanical vibration. Oil‑resistant and high‑temperature resistant outer sheath adapts to industrial field harsh environment.
Application Scenarios Steam turbine shaft vibration monitoring loop, gas turbine rotor displacement measurement, centrifugal compressor thrust bearing position supervision, large‑scale rotating machinery eddy‑current measuring circuit in petrochemical, power and metallurgy industries.
Performance Parameters Signal attenuation within working frequency band satisfies Bently proximity transducer system requirement. Impedance keeps stable under wide temperature fluctuation. Mechanical anti‑pull and anti‑bending performance meets industrial field wiring standard.
Structural Characteristics Precision coaxial inner conductor and insulating layer for fixed impedance parameter. Double‑layer overall shielding structure. Industrial high‑temperature resistant outer protective sheath. Both ends assembled with dedicated precision signal connectors for proximity transducer system.
Working Principle High‑frequency alternating gap voltage signal generated by proximity probe is transmitted to proximitor preamplifier through shielded coaxial cable. Cable maintains signal amplitude and phase without obvious distortion, so that preamplifier can normally complete gap‑voltage conversion processing.
Installation Requirements Lay cable separately, must not bundle and arrange together with high‑voltage power cables. Avoid sharp bending, sharp‑object scratching and extrusion damage to cable sheath. Screw both‑end connectors completely tightened. Reserve appropriate cable slack for equipment thermal expansion and mechanical vibration displacement.
