The 330730 extension cable belong to 3300 XL 11 mm Proximity Transducer System.It is not merely a simple wire, but a precision 75-ohm coaxial cable. Its primary function is to transmit the RF excitation signal emitted by the Proximitor sensor and the response signal returned by the probe without loss. The inherent resistance and capacitance characteristics of the cable itself directly affect the entire system's Scale Factor, linearity, and frequency response. Therefore, a dedicated, high-quality extension cable is the foundation for ensuring the accuracy and interchangeability of the entire measurement system.
Both the center conductor and the outer conductor (shield) of the 330730 extension cable have strictly controlled resistance values. For example, a 4-meter cable has a resistance of 1.0 ± 0.25 Ω between center conductors and a resistance of 0.3 ± 0.1 Ω between outer conductors. This consistency ensures the stability of the system's output signal.
The typical unit length capacitance of the 330730 extension cable is 69.9 pF/m. The distributed capacitance of the cable affects the system's high-frequency response, and this value is precisely controlled to ensure a flat frequency response (+0, -3 dB) within the system's bandwidth of 0-8 kHz.
Simultaneously, this cable utilizes Fluoroethylene Propylene (FEP) insulation material, which offers excellent chemical resistance, high-temperature resistance, and electrical insulation properties.
Frequently Asked Questions:
What configuration options are available for the 330730 extension cable?
Answer: This model can be selected for length, and configured as standard cable, armored cable, or FluidLoc cable. Among these, the FluidLoc option prevents oil and other liquids from leaking out of the machine through the cable's interior, making it ideal for oily environments such as turbomachinery.
What should be noted during the installation of the 330730 extension cable?
Answer: This model can be secured using ClickLoc connectors, and all models come with silicone tape that can be used instead of connector protectors. However, the use of silicone tape is not recommended if the connection between the probe and the extension cable will be exposed to turbine oil.
What is the compatibility of the 330730 extension cable like?
Answer: Any 330730 extension cable is perfectly interchangeable; compatibility issues need not be considered.
