Eddy-Current Probe Scaling and Gap Validation

This probe utilizes a target surface area scaling factor of 1.5 for 8 mm diameter probes. Calibration requires validation of the DC gap voltage at the monitor module. The system targets a nominal -10 VDC output at the proximity probe tip when centered in its linear range. Signal integrity is maintained through cross-talk suppression techniques inherent to the 3300 XL series design, ensuring stable rotor dynamics data acquisition.

Frequently Asked Questions

Q: What is the minimum bend radius for the standard cable?

A: The standard coaxial cable must maintain a minimum bend radius of 25.4 mm (1.0 in) to prevent dielectric stress and signal attenuation.

Q: Does the 330101 probe support hot-swapping?

A: No. Removal or insertion while the system is powered can induce transient voltages that may damage the Proximitor or the monitoring module. Always de-energize the loop before handling.

Q: What is the required thread engagement for installation?

A: A minimum of 5 full threads must be engaged into the mounting bracket to ensure mechanical stability and proper grounding continuity.

Field Installation Guidelines

Verify the probe tip is free of debris prior to installation. Apply anti-seize compound to the 3/8-24 UNF threads if operating in high-temperature environments. Ensure the connector mating surface is clean and dry; engage the ClickLoc connector until a positive mechanical lock is felt. Route the cable away from power conductors and variable frequency drive outputs to mitigate electromagnetic interference. Ground the cable shield at a single point only, typically at the termination panel, to prevent ground loops.
