The BENTLY 330130-045-00-00 is an integral part of the 3300 XL proximity transducer system. In eddy current displacement sensing, the cable is a tuned component of the resonant circuit. The "045" in the part number indicates a cable length of 4.5 meters. When combined with a 0.5-meter or 1.0-meter probe lead, it creates the standardized 5.0-meter system length required for accurate calibration of the Proximitor sensor.
The 330130 extension cable features a triaxial design with high-density shielding. This is critical for protecting the low-voltage radio frequency (RF) signal from Electromagnetic Interference (EMI) generated by large motors, generators, and switching gear. The robust shielding ensures that the "gap" voltage and vibration signals remain clean and accurate as they travel from the machine bearing to the control cabinet.

Equipped with gold-plated ClickLoc connectors, the 330130-045-00-00 ensures a low-resistance, corrosion-resistant connection. The ClickLoc mechanism prevents the connectors from vibrating loose over time. The cable jacket is made of FEP (Fluorinated Ethylene Propylene), providing excellent resistance to industrial oils, chemicals, and extreme temperatures typically found in steam turbine and compressor housings.
The "00-00" suffix indicates the cable does not include additional armored sleeving or specialized fluid-tight connectors, making it ideal for installation within conduit. For applications where the cable is exposed to high-pressure oil or moisture, the 330130 series ensures that the electrical properties remain stable, preventing signal drift that could lead to false vibration readings.
During installation, it is vital to maintain the minimum bend radius of the 330130-045-00-00 to avoid damaging the internal conductors. Using connector protectors (silicone sleeves) is recommended to prevent contamination and grounding of the outer shield to the machine case. Proper cable management ensures that the Bently Nevada protection system provides reliable data for the life of the machine.
