Technical Specifications Precision impedance‑controlled coaxial shielded cable. Operating temperature ‑40℃ ~ +125℃. Double‑layer shielding structure to restrain external electromagnetic interference. Fitted with Bently dedicated matching connectors at two ends. Outer sheath owns oil‑resistant, anti‑aging property, adapting to cabinet and field installation environment.
Functional Features Deliver gap voltage signal from proximity probe to proximitor preamplifier. Strict characteristic impedance control ensures signal integrity. Double‑layer shielding reduces external electromagnetic noise interference. High‑temperature and oil‑resistant outer sheath adapts to industrial harsh working condition. Special connectors guarantee reliable connection under vibration environment.
Application Scenarios Turbine, compressor, large motor shaft vibration and thrust displacement monitoring measuring loop for power plant, petrochemical and metallurgical industry machinery protection system.
Performance Parameters Signal attenuation complies with Bently proximity transducer system technical requirement. Impedance parameter remains stable under wide temperature variation. Mechanical performance satisfies long‑term industrial wiring application.
Structural Characteristics High‑precision coaxial inner core, double‑layer shielding layer, industrial‑grade anti‑aging outer sheath. Both ends equipped with dedicated signal connectors for proximity transducer system.
Working Principle The high‑frequency gap voltage signal generated by eddy‑current proximity probe is transmitted to proximitor preamplifier through shielded coaxial cable. The cable maintains signal amplitude and phase characteristics, providing complete original signal for subsequent signal conditioning and conversion inside proximitor.
Installation Requirements Carry out separate wiring laying, keep distance from high‑voltage power cable bundles. Avoid sharp bending, mechanical impact and extrusion damage to cable. Fully tighten threaded connectors at both ends. Leave proper cable slack for equipment vibration displacement.
Usage Notes Prohibit pulling cable by connectors. Prevent sheath scratch and corrosive medium damage. Ordinary coaxial cable cannot substitute for this dedicated cable. Inspect connector tightness during routine maintenance.
