Frequently Asked Questions (FAQ)

Q1: What gap range does the PR6423/10R‑010‑CN cover?
A1: It offers a calibrated linear range of 0 to 2.0 mm, suitable for most medium‑clearance machinery shafts.

Q2: Which proximitor should be used with this probe?
A2: The probe is optimised for pairing with Epro CON 011 or CON 021 proximity sensor modules.

Q3: Is the sensor interchangeable with other PR6423 probes?
A3: Yes. All PR6423 variants share identical electrical characteristics; any probe can replace another after proper mechanical alignment.

Q4: Can the probe operate in hazardous areas?
A4: An ATEX II 1G Ex ia IIC T4 certified version is available on request for Zone 0/1 installations.

Q5: How is the probe installed?
A5: Thread the probe into a radial or axial port so that the tip faces the conductive target, then lock it in place using the supplied jam nut.

Q6: Does cable length influence calibration?
A6: Each probe is factory‑matched to its cable length; altering cable length without recalibration will affect sensitivity and linearity.

Q7: What shaft materials are compatible?
A7: Carbon steel, stainless steel and Inconel provide the specified calibration constants; non‑ferrous alloys may require custom calibration.

Q8: How often is recalibration required?
A8: With proper installation, recalibration is generally unnecessary; periodic verification during shutdowns suffices.

Q9: What environmental sealing does the probe offer?
A9: The probe head is hermetically welded and rated to IP68, ensuring ingress protection against oil and water immersion.

Q10: What is the maximum extension cable length?
A10: The PR6423 system supports up to 10 m of integral cable; longer runs require a high‑integrity armour and a calibrated CON 021 module.
