Hardware Specifications

Mechanical Monitoring and Eddy-Current Scaling

The 3300 5 mm probe utilizes eddy-current probe scaling calibrated for precise vibration and position measurement. Maintaining signal integrity requires consistent gap voltage validation, with typical operational targets established at -10 VDC at the proximitor output. The probe is engineered for cross-talk suppression in high-density installations, preventing electrical noise injection from adjacent channels. Proper rotor dynamics analysis relies on the linear range of the transducer; ensure the probe gap is set to the manufacturer's recommended mid-range to prevent output saturation during shaft excursion.

Field Installation Guidelines

• Mechanical Installation
  • Ensure the probe tip is installed perpendicular to the target surface.
  • Secure the probe assembly using locknuts to prevent movement caused by machine vibration.
• Electrical Connection
  • Verify connector mating is secure and free of environmental contaminants.
  • Route signal cabling through dedicated instrumentation conduits, maintaining distance from high-voltage AC lines.
• Grounding
  • Maintain shield continuity through the connector interface, with grounding performed at the proximitor terminal block.

Frequently Asked Questions

• What is the primary purpose of the 3300 5 mm probe?

  The probe is designed for radial vibration and axial position measurement in smaller target applications where the 8 mm probe footprint is not suitable.

• Can the probe tip be cleaned if contaminated?

  Use a mild solvent that does not damage the PPS tip material; ensure the probe is completely dry before re-installation.

• How do I verify correct probe operation?

  Perform a gap voltage check; the output should track linearly with the physical gap distance.

• Is the probe compatible with 3300 XL proximitors?

  Compatibility depends on the system revision; consult the system documentation for impedance and frequency response matching.

• Does the probe require an external DC power source?

  No, it is a passive transducer powered by the associated proximitor sensor.

• How should I address high-frequency signal noise?

  Verify that the cable shield is properly grounded at the proximitor end and that no ground loops exist in the monitoring circuit.

• Can I use the probe in high-temperature environments?

  The probe is rated for operation up to 177 deg C; verify that the installation path does not expose the cable to extreme heat sources.

• Why is the transducer output saturated at high shaft speeds?

  This indicates that the target is exceeding the linear range of the probe, or the gap is set outside the specified operational parameters.
