Frequently Asked Questions (FAQ)

1. Can the 330854-080-24-CN extension cable be used in high-vibration environments?

   Yes, it is designed specifically for use in high-vibration zones such as turbine housings and compressor bodies. Its rugged construction ensures minimal signal degradation even under continuous mechanical stress.

2. What is the maximum total system length when using this cable with a 3300 XL probe and Proximitor?

   The total system length must be 15 meters (49.2 feet) or 20 meters (65.6 feet), depending on the system configuration. This includes the probe cable, extension cable (like 330854-080-24-CN), and the cable from the extension to the Proximitor.

3. Does the cable require shielding for EMI protection?

   No additional shielding is required. The 330854 series comes with double-shielded construction, which effectively protects signal integrity in environments with high electromagnetic interference.

4. How do I determine if 80 feet is the correct cable length for my setup?

   You must calculate the total system length between the probe tip and the Proximitor input. If 80 feet is too long, signal fidelity and phase response can be compromised. Always match the cable length to the factory-calibrated configuration.

5. Is field termination or customization of this cable recommended?

   No. Field termination is not recommended because it can affect calibration and signal accuracy. These cables are pre-terminated and calibrated at the factory to ensure proper system response.

6. What type of connectors does this cable use?

   It uses MIL-C-5015-style connectors, which are designed for secure, vibration-resistant engagement. These are industry-standard connectors used in most Bently Nevada systems.

7. Can this cable be used in proximity systems for axial as well as radial vibration monitoring?

   Yes, it supports both axial and radial position and vibration measurements, as long as it’s used with the appropriate probes and drivers from the 3300 XL family.

8. Is the 330854-080-24-CN interchangeable with the 330130 series cables?

   Functionally, both serve similar roles, but the 330854 is part of the newer 3300 XL system and provides improved durability, EMI shielding, and thermal tolerance. Mixing cables from different series is not recommended unless specified by the manufacturer.

9. What is the bend radius, and why is it important?

   The minimum bend radius is 2.5 inches (63.5 mm). Exceeding this can stress the cable’s internal shielding and insulation, possibly causing early failure or signal noise.

10. How often should this cable be inspected or replaced in critical systems?

    While the cable is built for long-term use, a visual and continuity inspection is recommended during every scheduled outage or maintenance cycle. If exposed to frequent mechanical movement, inspection frequency should increase.
