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 shortened in the field to match specific installation runs?

A: No. The electrical capacitance and impedance are factory-tuned to the specific length. Trimming or extending the cable will alter system-level sensitivity and necessitate re-calibration of the connected Proximitor and monitoring hardware.

Q: How does the triaxial construction affect installation?

A: The 75 ohm triaxial design provides superior shielding against electromagnetic interference. Ensure that the shield termination is maintained according to the system installation manual to prevent ground loops and signal noise.

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 strictly 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.
