PR6423 is a non-contact eddy-current probe family for radial or axial shaft displacement, position, eccentricity and speed/key applications. The probe is used with a compatible converter; CON041 supplies excitation, linearizes the sensor response and provides the voltage signal.

PR6423/002-001 CON041 FAQ
Can PR6423/002-001 CON041 be assembled from any PR6423 probe and any CON041? Not safely. Confirm probe suffix, cable arrangement, converter calibration, measuring range and target material as one chain.
Why can PR6423/002-001 CON041 show the correct gap but incorrect vibration amplitude? Static gap can appear plausible while sensitivity, converter calibration, cable length or target material causes dynamic scaling error.
What gap checks matter for PR6423/002-001 CON041 installation? Set the probe inside the linear range, confirm shaft runout and target geometry, then verify DC gap voltage through a full slow-roll cycle.
What should be captured before replacing PR6423/002-001 CON041? Record all suffixes, serial markings, cable length, converter adjustment, mounting depth, gap voltage, target material and monitor scaling.
How should PR6423/002-001 CON041 be accepted after installation? Check gap voltage, linear movement response, polarity, sensitivity, runout, dynamic signal, monitor scaling and alarm behavior.
