Eddy-Current Probe Scaling and Gap Voltage Validation
The hardware relies on eddy-current probe scaling to establish an average scale factor of 7.87 V/mm (200 mV/mil) when paired with AISI 4140 steel targets. Field commissioning demands gap voltage validation to ensure the probe operates within its linear range. Technicians must adjust the mechanical position until the Proximitor output reaches a target value of -10 VDC, representing the physical midpoint of the linear calibration envelope. Proper physical alignment mitigates cross-talk suppression issues and ensures accurate capturing of rotor dynamics without signal clipping.
Frequently Asked Questions
Q: What is the significance of the -10 VDC target voltage during installation?
A: The -10 VDC measurement represents the electrical center of the 2.0 mm (80 mils) linear range for the 3300 XL 8 mm transducer system, verifying correct physical gapping before recording data.
Q: Can the coaxial ClickLoc connector be disconnected while the monitoring rack is live?
A: Yes, the probe connector carries low-voltage high-frequency RF signals generated by the Proximitor, allowing physical disconnection without damaging the machine protection system monitors.
Field Installation Guidelines
- Mount the smooth-case probe using specialized split-collet brackets to prevent mechanical deformation of the probe barrel.
- Maintain standard physical clearance around the probe tip to prevent unintended side-view interactions with the machine casing or counterbores.
- Verify that the ClickLoc coaxial connectors are free from oil, moisture, or particulate contaminants before joining.
- Hand-tighten the coaxial connectors until an audible click is felt; do not use pliers or mechanical locking tools.
- Apply the included self-fusing silicone tape around the joined connector interface to provide environmental isolation outside the machine casing.
