Eddy-Current Probe Scaling and Gap Voltage Validation
Probe scale factor is factory-calibrated against a standard AISI 4140 target to ensure linear output across the defined range. Gap voltage validation should target -10 VDC at the Proximitor sensor output under static installation conditions. Eddy-current field interaction requires maintaining minimum separation distances between adjacent probes to suppress cross-talk effects in rotor dynamic monitoring arrays.
Frequently Asked Questions
Q: Can this probe be used with non-Bently Nevada extension cables?
A: No. Optimal performance requires matched 3300 XL extension cables and Proximitor sensors to maintain calibrated scale factor and frequency response.
Q: Is hot-swapping supported during machinery operation?
A: Hot removal or insertion is not recommended; disconnect power to the Proximitor sensor before replacing the probe to prevent transient signal errors.
Q: What is the maximum probe tip pressure rating?
A: The probe tip seal is rated to 7 bar (100 psi); exceeding this may damage the PPS tip material.
Field Installation Guidelines
Mount the probe using the 3/8-24 UNF thread with proper anti-vibration locking measures. Ensure the connector interface is clean and dry prior to mating; apply threaded sealing compound only to case threads, avoiding electrical contact surfaces. Maintain separation from other probes to minimize electromagnetic coupling. Ground the outer shield of the coaxial cable at the Proximitor sensor end only, leaving the probe end floating to avoid ground loops. Verify gap voltage after mechanical installation to confirm correct probe-to-target spacing.
