To ensure the reliable operation of the Bently Nevada 330130-075-00-00 Extension Cable, follow these installation guidelines:
System Length Matching: Ensure that the total length of the probe plus the extension cable aligns with the Proximitor Sensor's requirements. For example, a 9.0m Proximitor requires a 1.5m probe plus this 7.5m extension cable.
Connector Integrity: Use the ClickLoc connectors, ensuring they are clean and dry before mating. A secure connection should provide a noticeable "click."
Minimum Bend Radius: Do not exceed the specified minimum bend radius of 25.4 mm to avoid impedance changes and calibration errors.
Cable Protection: Route the non-armored cable through a conduit or cable tray to protect it from mechanical damage and chemical exposure.
Grounding: Ground the outer shield only at the Proximitor Sensor end to prevent ground loops.
The Bently Nevada 330130-075-00-00 Extension Cable is designed to endure extreme environments, ensuring durability and reliable performance. Its high-capacitance precision cable minimizes signal degradation and electrical interference, making it ideal for vibration monitoring applications.
