It is an Emerson EPRO eddy-current measurement assembly combining the PR6423/002-000 sensor configuration with a CON021 signal converter.
The published matrix identifies M10×1 sleeve thread, no armored cable, sensor-length code 2, adapter plug, 4 m total cable and LEMO termination. Confirm the complete label before supply.
Emerson publishes a nominal static range of ±1.0 mm for PR6423.
The PR6423 guide gives 50 to 500 µm as the recommended dynamic range.
The published sensitivity is 8 V/mm using 42CrMo4 reference material. Target material and geometry affect the measurement and must be verified.
The documented operating range is −35 to +180 °C, with +200 °C allowed only for a short time as stated by Emerson.
Do not assume so. Confirm the converter type, sensor family, cable length, termination and calibration pairing.
Verify probe gap, target material, runout, cable routing, connector condition, converter supply and the required output scaling.
Send photographs of both PR6423 and CON021 labels, the full suffix, quantity, destination and existing cable or connector details.
Send the model, complete part number, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
Technical information is based on the linked official Emerson documentation. Final suitability must be verified against the exact installed unit and current manufacturer guidance.
