Eddy-Current Probe Scaling and Gap Voltage Validation

The 3300 XL probe system maintains a linear scale factor of 7.87 V/mm when interfaced with a matched 3300 XL Proximitor Sensor. Gap voltage validation targets a nominal -10 VDC bias point for static position monitoring. Cross-talk suppression is achieved through the defined minimum probe-to-probe spacing distances outlined in the 3300 XL installation manual, ensuring accurate rotor dynamics data acquisition without signal interference.

Frequently Asked Questions

Q: What is the required thread engagement for installing the 16699-10-02-02 probe?

A: A minimum of 5 full threads must be engaged in the machine housing to ensure mechanical stability and ground continuity.

Q: Does the probe require calibration after replacing the extension cable?

A: No. The 3300 XL system is designed for interchangeability. Provided the probe, extension cable, and Proximitor are all 3300 XL components, no field calibration is required.

Q: What is the maximum permissible cable bend radius during installation?

A: The coaxial cable must not be bent at a radius smaller than 25.4 mm (1 inch) to prevent dielectric damage and signal attenuation.

Field Installation Guidelines

Install the probe perpendicular to the target surface with an air gap within the linear range (typically 0.25 mm to 2.25 mm from the probe face). Ensure the ClickLoc connector is fully seated and secured with the provided connector protector to maintain environmental sealing. Ground the machinery casing properly to prevent ground loops. Route the coaxial cable away from high-voltage power conductors and avoid running it parallel to AC motor leads to minimize electromagnetic interference.
