Eddy-Current Probe Scaling and Gap Voltage Validation
The 3300/01-01-00 supports precise eddy-current probe scaling through linearized target calibration against API 670 requirements. Gap voltage validation targets a nominal -10 VDC bias under static conditions, ensuring transducer health prior to rotor dynamics measurement. Signal crosstalk suppression is maintained between channels via isolated return paths and screened cabling practices within the rack assembly.
Frequently Asked Questions
Q: Does the 3300/01-01-00 support hot-swap replacement without rack power-down?
A: No. Backplane power must be removed before removal or insertion to prevent damage to connectors and maintain signal integrity.
Q: What is the alarm inhibit duration during power-up?
A: The internal Power-up Inhibit function suppresses alarm outputs for approximately 2 seconds after supply stabilization.
Q: Can the buffered Keyphasor outputs drive multiple diagnostic devices simultaneously?
A: Yes, provided total load impedance does not fall below 10 kohm per output to avoid signal attenuation.
Field Installation Guidelines
Mount the module into the designated leftmost slot of the 3300 rack to ensure correct backplane addressing. Use shielded twisted-pair cable for all transducer wiring, terminating shields at the rack ground busbar. Verify gap voltage at each proximity probe before final rack commissioning. Ensure all dry-contact inhibit wiring uses adequately rated control cables segregated from high-voltage conductors. Maintain minimum clearance around ventilation slots to prevent thermal accumulation.
