- Low high frequency signal attenuation
- Good resistance to aging under high temperature and oil environment
- Stable shielding performance for long term operation
Material Composition Central signal conductor uses high purity copper wire. Insulation layer uses high temperature resistant polymer material. Full metal braided shielding layer wraps insulation layer. Outer jacket uses oil resistant, high temperature resistant composite polymer. Connector parts use stainless steel and corrosion resistant insulating material.
Structural Characteristics Flexible round cable structure. One end is pre-installed connector for connecting probe, the other end is connector for signal converter. The metal braided shielding layer covers the whole cable length. Outer jacket has wear resistant property. Cable diameter is designed for convenient wiring inside narrow equipment space.
Working Principle The extension cable transfers high frequency excitation signal from signal converter to the coil inside probe tip. The variation signal generated by eddy current effect is transmitted back to the converter through the same cable. The fixed impedance of the cable ensures that the signal change only comes from the gap variation between probe and metal shaft, instead of cable impedance change. The shielding layer blocks external electromagnetic noise from affecting high frequency weak signal.
Installation Requirements Lay cable along fixed cable routing of equipment bearing housing. Fix cable with cable clamps, avoid sharp bending and sharp corner extrusion. Keep cable away from high voltage power cables. Do not pull the cable with large tension. Connect connectors tightly and check locking state.
Use Precautions Avoid scratching the outer jacket during installation. Prevent heavy object pressing on the cable. Check connector tightness regularly. Replace the cable immediately if jacket damage or insulation deterioration appears.
