Eddy-Current Probe Scaling and Gap Voltage Validation
The 16925-10 supports TSI front-end configurations where eddy-current probe scale factors must align with driver input impedance and calibration constants. For gap voltage validation, maintain target levels near -10 VDC to ensure linear displacement measurement ranges. Correct scaling prevents signal saturation and preserves rotor dynamics data fidelity in high-energy turbomachinery.
Frequently Asked Questions
Q: Can the 16925-10 be used with both 3300 and 3500 series monitors?
A: Yes. Electrical characteristics are compatible with both series when paired with matching driver electronics.
Q: Is hot-swapping supported during operation?
A: No. Disconnect power from the monitoring channel before replacing or re-terminating the cable to avoid transient surges.
Q: What is the recommended shield termination method?
A: Terminate the braided shield to the designated ground point at the monitor end only, leaving the sensor end insulated to prevent ground loops.
Field Installation Guidelines
Route the cable within protective conduit or tray to prevent mechanical abrasion. Maintain separation of at least 30 cm from high-voltage AC feeders to minimize inductive coupling. Avoid sharp bends beyond the specified bend radius. Verify torque on ring terminal connections to manufacturer-recommended values to ensure stable contact resistance. Confirm continuity and insulation resistance prior to energizing the monitoring system.
