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 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 the cable length be modified during field installation?

A: No. The electrical characteristics, including capacitance and impedance, are factory-tuned to the specific length. Altering the cable length will invalidate system calibration and introduce measurement errors.

Q: What is the requirement for cable routing near high-voltage lines?

A: Cables must be routed in dedicated conduit, isolated from AC power lines. A minimum separation of 300 mm from high-voltage cables is recommended to minimize electromagnetic coupling.

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 conduit or dedicated cable trays to prevent mechanical damage. Ensure the minimum bend radius is not exceeded to avoid stressing the internal conductor.
3. Clean all connector pins with an appropriate contact cleaner if exposure to oils or moisture occurred during installation.
4. Finger-tighten all coaxial connectors. Use of tools to overtighten may damage the connector threads or internal pin alignment, resulting in intermittent signals.
5. Verify the total system length (Probe + Extension Cable) matches the configuration programmed in the monitor or Proximitor module.
