Description

01 / SENSOR CHAIN

Emerson EPRO PR6423/015-000-CN CON021 combines an 8 mm non-contact eddy current sensor with a matching signal converter. The sensor provides an 8 V/mm incremental scale factor over a 2 mm linear range, supporting precise radial and axial shaft displacement measurements. Its nominal operating point is approximately 1.5 mm, with a 0.5 mm initial air gap used during setup. The stainless-steel sensor body, PEEK tip and PTFE-insulated cable are engineered for demanding rotating machinery environments.

02 / MACHINE ROLE

The complete measurement chain supports continuous observation of shaft position, eccentricity, radial movement and speed-related reference signals. It interfaces with machinery protection and condition-monitoring systems used on turbines, compressors, pumps and fans. Correct installation depends on the specified target material, cable configuration and calibrated converter pairing. Verification of the air gap and signal polarity helps maintain dependable operation after installation or replacement.

FAQ

What initial air gap should be used when installing PR6423/015-000-CN CON021?

Use a 0.5 mm initial air gap, then confirm the converter signal and final operating position during commissioning.

Which shaft material is the calibration reference for PR6423/015-000-CN CON021?

The reference material is 42CrMo4 / AISI 4140 ferromagnetic steel.

How should the 2 mm linear range of PR6423/015-000-CN CON021 be used?

Position the target within the calibrated linear range and avoid operation outside the verified gap window.

Can PR6423/015-000-CN CON021 monitor speed-related signals?

Yes. The sensor system can support speed or key-reference measurement when installed with the proper target geometry.

What must be checked before replacing only the sensor in PR6423/015-000-CN CON021?

Confirm the sensor variant, cable configuration, converter pairing and final air-gap setting before return to service.

When will PR6423/015-000-CN CON021 be shipped after payment?

Confirmed stock is released immediately after payment, with carrier and tracking details provided.
