Eddy-Current Transducer Calibration and Gap Voltage Validation
The passive extension link maintains the critical tuning matching criteria required to record high-speed rotor dynamics. Field validation practices require precise matching of the 4.0-meter extension parameters with a 1.0-meter probe lead to guarantee accurate gap voltage validation (-10 VDC targets) at the Proximitor block. Because the matched capacitance preserves the original eddy-current probe scaling, this shielded physical link delivers rigorous cross-talk suppression and prevents phase attenuation across high-frequency measurement fields.
Frequently Asked Questions
Q: Can a 4.0-meter extension cable couple directly with a standard 3300 XL 8mm proximity probe?
A: No, the 3300 NSv system incorporates distinct internal impedance tuning parameters. Combining this cable with standard 8mm probe elements alters the overall circuit loop balance and invalidates factory calibration curves.
Q: Does the FEP outer jacket protect internal signal paths against industrial fluids?
A: The FEP compound provides high-level chemical immunity against synthetic lubricants, cooling fluids, and petroleum hydrocarbons commonly found inside machine housings.
Field Installation Guidelines
Route the flexible FEP-jacketed coaxial line through dedicated, grounded metal conduits separated from three-phase industrial mains to eliminate electromagnetic interference loops. When connecting the miniature ClickLoc terminals, ensure the physical locking shoulder engages fully to seal out moisture and maintain reliable electrical contact. Avoid exceeding the minimum specified bend radius of 25.4 mm during installation runs, and ground the overall coaxial outer shield layer at the terminal junction inside the main Proximitor housing.
