8 MM SENSOR · 2 MM LINEAR RANGE · TURBOMACHINERY MEASUREMENT
Emerson PR6423/01R-111 8 mm Eddy Current Sensor
A non-contact 8 mm eddy-current sensor execution for shaft displacement, position, eccentricity and speed measurement.
Overview
PR6423/01R-111 belongs to Emerson’s PR6423 family of 8 mm eddy-current sensors for critical turbomachinery. The sensor observes a conductive target without mechanical contact and supports radial or axial shaft displacement, position, eccentricity and speed measurements.
Emerson specifies a 2.0 mm linear range, 0.5 mm initial gap and an incremental scale factor of 8 V/mm within the published temperature band. The complete suffix remains part of the installed mechanical and cable identity.
Specifications
Features
Non-contact measurement
Avoids probe wear and mechanical loading of the observed shaft.
Defined transfer characteristic
Provides the published 8 V/mm scale within the approved sensor-converter chain.
High-temperature probe construction
Supports continuous sensor service to 180 °C with the specified one-metre cable arrangement.
Machine-focused geometry
The 8 mm family suits displacement work where target size and mounting clearance meet the installation rules.
About IndustryParts

IndustryParts prepares PR6423/01R-111 enquiries around the complete manufacturer label, requested quantity and destination. For controlled replacements, include the host-system record, field photographs and configuration evidence that apply to this exact execution.
Applications
Radial vibration
Observing shaft motion relative to a bearing or machine reference.
Axial position
Following thrust position when the target and bracket geometry are approved.
Speed and eccentricity
Providing a non-contact signal for documented rotating-machine monitoring functions.
Lifecycle
Survey the installation
Record target material, shaft diameter, probe bracket, gap, cable route and converter identity.
Protect the probe
Avoid cable twisting, uncontrolled connector force and target contact while installing PR6423/01R-111.
Validate the chain
Confirm gap voltage, linear movement, polarity, channel scale and alarm behavior before return to service.
FAQ
Can PR6423/01R-111 be selected from the PR6423 family name alone?
No. The complete suffix, mechanical form, cable identity and converter relationship must match the installed measurement chain.
What target evidence should accompany a PR6423/01R-111 enquiry?
Provide shaft diameter, target material, available flat area, mounting thread or bracket details and the expected displacement range.
Does PR6423/01R-111 measure vibration without a signal converter?
No. The probe is part of an eddy-current measurement chain and requires the compatible converter and monitor-channel scaling.
What can cause an incorrect gap reading with PR6423/01R-111?
Target geometry, material, loose mounting, damaged cable, connector contamination and an unmatched converter can all affect the result.
Which checks prove PR6423/01R-111 is ready after service?
Document mechanical clearance, stable gap voltage, linear response through the required travel and correct monitor indication and alarms.
