Eddy-Current Probe Scaling & Gap Voltage Validation

This probe utilizes eddy-current sensing physics to generate a linear voltage output proportional to target distance. For static verification, the system requires a gap voltage validation check targeting -10 VDC at the transducer interface module. This ensures the probe tip maintains the correct standoff from the conductive surface, preventing non-linearity in rotor dynamics data acquisition. Signal cross-talk suppression is achieved through the miniature coaxial ClickLoc connector design, which maintains consistent impedance matching across the 3300 XL series architecture.

Frequently Asked Questions

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

A: The standard cable must be installed with a minimum bend radius of 25.4 mm (1.0 inch) to prevent dielectric breakdown and signal attenuation.

Q: Can this probe be mounted directly into a pressurized vessel?

A: Yes, when ordered with the appropriate agency approvals (CSA, ATEX, IECEx), the probe assembly meets explosion-proof requirements for hazardous locations, provided the thread engagement meets the specified torque values.

Q: Is hot-swapping supported on this probe line?

A: No. The 3300 XL probe system does not support hot-swapping. Power must be removed from the associated monitor module before disconnecting or connecting the probe to prevent transient voltage spikes that could damage the conditioning electronics.

Field Installation Guidelines

Install the probe ensuring the 3/8-24 UNF threads engage a minimum of 5 full turns into the mounting bracket. Do not apply thread sealant to the unthreaded section of the probe case. Ground the shield drain wire directly to the monitor chassis ground terminal; do not tie shield grounds together at multiple points to avoid ground loops. Verify the gap voltage at the monitor terminal strip prior to final machinery start-up to confirm proper probe tip clearance.
