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 be field-modified or shortened?

A: No. The electrical capacitance and impedance are factory-tuned to the specific length. Any modification to the cable structure or length will invalidate the system calibration and introduce measurement errors.

Q: Are the integrated connector protectors required for installation?

A: Connector protectors are recommended to prevent ingress of conductive dust or moisture at the connector interface, which could cause signal drift or intermittent noise floor elevation in harsh operating environments.

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.
