      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • The PR6423/10R-010 probe is selected as part of a calibrated shaft-measurement chain; its installation geometry and cable route must suit the existing machine.
      Service focus: Preserve shaft target and cold gap
      System dependency: Match converter and total cable chain
      Installation decision: Use the selected mounting direction
      The PR6423/10R-010 order code selects a 3/8-24 UNF case and unarmored cable. The reverse mount construction determines how the probe is fitted through the machine casing; retain the matching holder and accessible cable path when replacing an installed sensor.

      A PR6423 probe forms one part of a matched proximity-measurement chain. The conditioned signal can support radial vibration, axial position or eccentricity monitoring when the converter, extension cable, target material and monitor input are selected together. The family range and scale factor belong to that calibrated chain.

      For a service change, preserve the original probe position, target surface and cold gap. Route the cable within the documented bend limits, confirm the adapter and LEMO connection, and compare the restored signal with a known mechanical position before returning the channel to protection service.
      Measurement system reference: PR642x proximity measuring chain. Match the installed configuration and interfaces.
      Technical downloads for Epro PR6423/10R-010: an Apter Power technical reference and an installation and commissioning guide.
      These Apter Power documents support product identification and service planning. Apply the approved system and site procedures during installation.
      Application context: Use the proximity signal for radial shaft movement, axial position, or slow-roll geometry in a machinery-monitoring installation configured for this probe family.

      Compatibility scope: The probe, extension cable, converter, target material and monitor input form one calibrated chain; retain the offered mounting thread and cable execution.
      Installation and commissioning checks for Epro PR6423/10R-010.
      Match the full order code

      Compare the complete PR6423/10R-010 marking with the installed probe and converter documentation.

      Preserve the mounting geometry

      Keep the 3/8-24 UNF engagement, probe position and intended reverse mount arrangement.

      Check the measurement chain

      Confirm the converter, extension cable, adapter and monitor input as one calibrated system.

      Protect the cable route

      Allow clearance for the standard unarmored construction and its minimum bending radius.

      Set the cold gap

      Adjust the probe-to-target position using the approved converter output and site procedure.

      Verify channel behavior

      Compare the restored gap and dynamic response with the pre-service machine record.

      Technical notes

      Technical basis: Emerson PR6423 Specifications Sheet, 8mm Eddy Current Sensor, December 2024.

      Applicability: PR6423 electrical and environmental figures describe the matched 8 mm sensor family. Confirm converter and installation applicability to the offered complete order code.

      Mounting relationship: The reverse-mount case and 3/8-24 UNF thread determine access and mechanical fit at the probe holder. Establish the target gap only after the mounting direction and cable exit are confirmed.

      FAQ View All FAQ

      • How is the converter pairing verified for PR6423/10R-010?
        Compare the installed converter and total cable arrangement with the approved PR6423 measurement-chain configuration; a matching tip alone is insufficient.
      • What target preparation matters before setting PR6423/10R-010?
        Inspect the shaft surface and material at the selected track and remove burrs or deposits that alter the apparent gap.
      • Why can PR6423/10R-010 give a changed baseline after replacement?
        Differences in cold gap, target track, cable chain or converter calibration can shift the steady output; compare all four with the service record.
      • How should cable routing be assessed for PR6423/10R-010?
        Check mechanical clearance and the bend radius of the selected cable construction, especially at the casing exit and adapter.
      • Can PR6423/10R-010 alone establish a protection trip?
        No. Trip behavior depends on the matched converter, monitor configuration, alarm limits and approved machine logic.
      • What is an appropriate commissioning check for PR6423/10R-010?
        Record a stable cold-gap output, then compare the monitored displacement channel with a known machine condition under site controls.
      • How is a false intermittent reading from PR6423/10R-010 isolated?
        Inspect connector seating, cable continuity, shielding, converter supply and target runout before attributing it to the probe.
      • What should be recorded before removing PR6423/10R-010?
        Record the exact marking, mounted insertion position, target track, cable path and converter/channel identification.
