Emerson PR6423/003-130 8 mm Eddy Current Sensor
A standard-mount 8 mm eddy-current sensor with a 55 mm sleeve, unarmored cable construction and an 8 m Lemo-terminated lead.
Technical Summary
Emerson PR6423/003-130 is a PR6423 8 mm eddy-current sensor for non-contact measurement of shaft displacement, position, eccentricity and speed on critical rotating machinery.
The ordering code identifies an M10 × 1 standard body without cable armor, a 55 mm case length, no adapter plug, an 8 m cable and a Lemo cable end. These fields distinguish PR6423/003-130 from nearby PR6423 executions.
The sensor is calibrated as part of an eddy-current measurement chain. Target material, shaft diameter, converter type, cable routing and hazardous-area requirements must be confirmed together.

Features
Non-contact measurement
Measures shaft motion without mechanical loading of the observed surface.
Order-code-defined mechanics
The 003 segment fixes the M10 × 1 body and 55 mm sleeve geometry.
Eight-metre integral lead
The 130 suffix specifies no adapter plug, an 8 m lead and Lemo termination.
Harsh-machine construction
A stainless-steel case, PEEK tip and PTFE cable support turbomachinery service.
Compatibility
Converter and calibration
Use the compatible Emerson converter and preserve the calibrated system length and scale.
Mechanical fit
Confirm M10 × 1 mounting, 55 mm sleeve reach, probe clearance and cable bend radius.
Target condition
Check shaft material, minimum diameter, surface finish, runout and the intended measurement direction.
Area approval
Hazardous-area classification depends on the complete sensor/converter system and its installed documentation.
Replacement
Record the existing chain
Capture PR6423/003-130, converter label, gap voltage, mounting depth, cable route and machine baseline.
Set the mechanical gap
Install without stressing the lead and establish the documented initial air gap against the correct target.
Confirm system response
Verify stable gap voltage, linear movement response, polarity, vibration signal and monitor alarm behavior.

FAQ
Q01
What does the 003 segment identify on PR6423/003-130?
+
It identifies the M10 × 1 standard-body execution with a 55 mm case length and no cable armor.
Q02
What does the 130 suffix mean on PR6423/003-130?
+
It selects no adapter plug, an 8.0 m cable and a Lemo cable end.
Q03
Can PR6423/003-130 replace another PR6423 with a different suffix?
+
Only after thread, sleeve length, armor, adapter, total cable length, cable end and converter calibration all match.
Q04
Which target information matters for PR6423/003-130?
+
Confirm shaft material, diameter, surface condition, runout, intended gap and the measurement direction.
Q05
What closes a PR6423/003-130 installation?
+
Record final gap voltage, cable routing, converter identity, signal polarity, linear response and monitor alarm checks.
