Measures shaft motion without mechanical contact or loading.
Product Overview
PR6423/016-030 is a complete ordering execution in Emerson EPRO’s PR6423 family of 8 mm eddy-current sensors. The /016-030 suffix must remain intact during selection.
Emerson specifies the PR6423 family for non-contact measurement of radial or axial shaft displacement, position, eccentricity and speed in critical turbomachinery.
The base family uses a 2 mm measuring range and is paired with an approved converter and mechanical installation. Exact cable, connector and mounting execution must be confirmed from the full label.

Features
Supports radial displacement, axial position, eccentricity and speed applications in the documented sensor family.
Uses the published 2 mm range and 8 V/mm scale-factor architecture of PR6423.
Retains the full /016-030 ordering execution for cable, connector and mounting control.
Applications
- Radial shaft vibration monitoring on turbines, compressors, pumps and generators.
- Axial position and eccentricity measurement in compatible monitoring chains.
- Speed or phase-related sensing where the approved converter and target geometry are used.
- Exact-execution replacement in an existing PR6423 measurement loop.
Installation
- Record the complete probe, extension and converter labels plus the existing mechanical gap.
- Inspect the target surface, probe thread, cable route, connector and environmental sealing.
- Set the probe using the approved static gap and converter characteristic rather than physical appearance alone.
- Verify bias voltage, scale factor, polarity, alarm logic and machine response before return to service.

FAQ
What evidence should accompany a PR6423/016-030 enquiry?
Provide clear probe and converter labels, installation photographs, cable routing, connector, mounting thread, target material, quantity and destination.
Can a different PR6423 suffix replace PR6423/016-030?
Not by family name alone. Confirm the complete mechanical, cable and connector execution and the approved converter pairing.
How should a stored PR6423/016-030 sensor be handled?
Protect the sensing tip, thread, cable and connector from impact, tight bends, moisture and contamination; retain its identification tag.
What should be checked if the PR6423/016-030 signal drifts?
Review the static gap, target surface, connector condition, cable route, converter supply and grounding before replacing parts.
What proves PR6423/016-030 is ready after installation?
Document the exact execution, mechanical gap, stable bias voltage, correct scale factor, clean trend and approved alarm-channel test.
