Hardware Specifications

Eddy‑Current Scaling and Gap‑Voltage Validation

The probe maintains calibrated eddy‑current scaling when paired with matched NSv extension cables and proximitor modules. Gap‑voltage behavior aligns with the −10 VDC reference used in NSv systems, supporting consistent displacement interpretation across rotor‑dynamic monitoring applications. The M10 x 1 threaded body ensures stable mechanical seating, while controlled coaxial impedance minimizes cross‑talk within multi‑channel racks.

Frequently Asked Questions

Q: Does the probe require a specific proximitor model for correct scaling? A: Yes. NSv probes must be paired with NSv‑rated extension cables and proximitor modules to maintain factory‑matched impedance and linearity.

Q: Can the ClickLoc connector be re‑terminated in the field? A: No. The connector is factory‑assembled. Field re‑termination may alter impedance and degrade displacement accuracy.

Q: Will cable routing near high‑current conductors affect the signal? A: Yes. Eddy‑current systems are sensitive to electromagnetic interference; maintain separation from high‑current wiring.

Field Installation Guidelines

Ensure full seating of the M10 x 1 threaded section to maintain probe‑to‑shaft alignment. Route the coaxial cable with gentle bend radii to preserve impedance. Bond shielding at the proximitor end only to avoid ground‑loop formation. Maintain at least several centimeters of separation from high‑current conductors or variable‑frequency drive outputs. Apply strain relief to prevent vibration‑induced connector motion.
