Eddy-Current Probe Scaling & Rotor Dynamics

This 11 mm probe operates via eddy-current physics to generate a dynamic electromagnetic field at the probe tip, measuring distance to a conductive target. To achieve the specified eddy-current probe scaling of 3.94 V/mm (100 mV/mil), this 10-meter probe is designed for extended applications and must be connected directly to a matched 3300 XL 11 mm Proximitor calibrated for a 10-meter system without intermediate extension cables. Proper physical installation and depth adjustment are required to ensure the correct gap voltage validation, targeting a baseline reading of -10 VDC at the center of the linear calibration envelope. This electrical stabilization is critical for tracking high-speed rotor dynamics and ensuring robust cross-talk suppression between closely mounted sensors.

Frequently Asked Questions

Q: Can this 10-meter total length probe be used with a standard 9-meter Proximitor?

A: No. Connecting a 10-meter probe to a 9-meter calibrated Proximitor creates an impedance mismatch. This mismatch alters the system calibration curve and will lead to inaccurate displacement and vibration measurements.

Q: Is an extension cable required for this specific configuration?

A: No. Because this probe option features an integrated 10-meter total cable length (Option 10), it connects directly to a 10-meter system Proximitor sensor, eliminating the need for an external extension cable.

Field Installation Guidelines

Mechanical Installation and Torque: Thread the probe body into the mounting port. Do not exceed 22.6 N-m (200 in-lb) of torque when tightening the mounting locknuts on the M14 x 1.5 threads to prevent physical damage to the internal casing.
Adjusting the Gap Voltage: Slowly rotate the probe toward the target surface while monitoring the Proximitor sensor output voltage. Secure the probe locknuts once the output registers the target gap voltage of -10.0 VDC (typically corresponding to a nominal physical gap of 2.0 mm or 80 mils for 11 mm systems).
Bending Radius and Cable Routing: Ensure the unarmored cable maintains a minimum bend radius of 25.4 mm (1.0 inch) during routing. Protect the ClickLoc coaxial connection using the integrated connector protector to isolate the signal path from machine ground.
