Hardware Specifications

Eddy-Current Probe Scaling and Signal Integrity

The 330130 extension cable maintains the characteristic impedance required for the 3300 XL proximity transducer system. Proper system operation relies on gap voltage validation, with target values typically centered at -10 VDC within the linear operating range. Deviations in cable length or impedance mismatch directly affect the accuracy of rotor dynamics measurements. The design utilizes high-frequency shielding to provide cross-talk suppression in industrial environments, preventing external electromagnetic interference from introducing noise into the transducer signal path.

Frequently Asked Questions

Q: Can this cable be used with 3300 series components?

A: The 3300 XL system is designed for component interchangeability within the 3300 XL series. While it may provide backward compatibility with other systems, proper scaling and gap voltage validation must be verified to ensure measurement accuracy.

Q: Is the cable length field-adjustable?

A: No. Factory calibration is performed based on the specific total system length (Probe + Extension Cable + Proximitor). Modifying the length requires system-level recalibration.

Field Installation Guidelines

1. Ensure all system power is isolated before disconnecting or connecting transducer components to prevent electrical transients.
2. Route the extension cable through dedicated conduit or cable trays to minimize mechanical stress and interference. Ensure the minimum bend radius is maintained to protect the internal coaxial structure.
3. Clean all connector pins with an appropriate electronic contact cleaner prior to mating to ensure optimal signal continuity and minimize resistance at the connection points.
4. Finger-tighten all coaxial connections. Do not utilize mechanical tools, as over-torquing can damage the internal connector threads or center pin alignment.
5. Verify that the total system length matches the configuration settings programmed in the monitor or Proximitor module.
