Functional Features The extension cable features gold-plated brass high-temperature ClickLoc connectors at both ends for secure, vibration-resistant connections. The FluidLoc design creates an internal barrier that prevents fluids from migrating through the cable and reaching the Proximitor Sensor electronics. The cable is designed for complete interchangeability within the 3300 XL 25 mm system without matching or calibration. The multiple agency approvals enable deployment in hazardous area environments.
Application Scenarios Connecting 25 mm proximity probes to Proximitor Sensors in steam turbine differential expansion monitoring systems, extending probe reach in large turbine installations, routing signals through hot machine areas in power plants, connecting vibration probes in petrochemical processing equipment, axial position measurement systems in heavy machinery where fluid exposure is present.
Performance Parameters The cable maintains a characteristic impedance of 75 Ω with capacitance of 69.9 pF/m. The FluidLoc construction maintains performance specifications across the full -35°C to +200°C temperature range. When combined with a 1.0 meter probe, this cable creates a 5.0 meter electrical length system compatible with 5.0 meter Proximitor Sensors. The signal attenuation is minimal across the operational frequency range.
Material Composition The cable conductors are copper with PFA insulation. The shielding is braided copper. The connector bodies are gold-plated brass. The FluidLoc construction includes specialized internal barriers to prevent fluid migration along the cable interior.
Structural Characteristics The cable has a 4.0 meter overall length with precise electrical length tolerances. Both ends are terminated with high-temperature ClickLoc connectors. The cable outside diameter is appropriate for the FluidLoc construction. The cable is marked with the part number and electrical length information.
Working Principle The extension cable transmits the high-frequency RF signal from the Proximitor Sensor to the probe tip and returns the modified signal back to the Proximitor Sensor. The triaxial design maintains signal integrity by providing separate inner and outer shielding. The FluidLoc construction prevents moisture and oil from entering the cable interior while maintaining full electrical performance.
