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: Is this extension cable compatible with legacy 3300 or 7200 series Proximitor sensors?

A: No. The 3300 XL system is impedance-matched as a complete chain. Utilizing this cable with non-3300 XL components will result in incorrect scale factors and loss of measurement accuracy.

Q: Can the cable length be field-adjusted to accommodate installation variations?

A: No. The electrical capacitance and impedance are calibrated based on the specific factory-manufactured length. Trimming or extending the cable will alter the system-level sensitivity and require re-calibration of the monitoring hardware.

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 (Probe + Extension Cable) matches the configuration settings programmed in the monitor or Proximitor module.
