Functional Features The extension cable features gold-plated brass ClickLoc connectors at both ends for secure, vibration-resistant connections. The triaxial construction provides excellent EMI/RFI shielding. The standard FEP insulation offers high temperature capability and chemical resistance. The cable is designed for complete interchangeability within the 3300 XL 11 mm system without matching or calibration.
Application Scenarios Connecting 11 mm proximity probes to Proximitor Sensors in turbine monitoring systems, extending probe reach in compressor installations, routing signals around hot machine surfaces, connecting vibration probes in pump monitoring systems, axial position measurement systems, differential expansion monitoring installations.
Performance Parameters The cable maintains a characteristic impedance of 75 Ω with capacitance of 69.9 pF/m. The DC resistance from center conductor to center conductor is 1.0 ± 0.25 Ω for the 4.0 meter length. The cable is electrically matched to 5.0 meter system length Proximitor Sensors when used with 1.0 meter probes. The signal attenuation is minimal across the 0 to 8 kHz frequency range.
Material Composition The cable conductors are copper with FEP insulation. The shielding is braided copper. The connector bodies are gold-plated brass. The outer jacket is FEP. The cable does not include armor in this configuration.
Structural Characteristics The cable has a 4.0 meter overall length with a tolerance appropriate for the system electrical length matching requirements. Both ends feature miniature coaxial ClickLoc male connectors. The cable has a 3.7 mm maximum outside diameter. The construction is non-armored, providing flexibility for routing in confined spaces.
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 cable length is precisely controlled to match the electrical length requirements of the 3300 XL transducer system.
