Emerson EPRO PR6424/006-030 Eddy Current Sensor
A PR6424 large-shaft eddy current sensor supplied under the complete /006-030 identifier.
Overview
PR6424/006-030 belongs to the Emerson EPRO PR6424 sensor family for non-contact shaft position and vibration measurement. The PR6424 geometry uses a 16 mm sensing tip and supports large-shaft applications with a nominal sensitivity of 4 V/mm.
PR6424/006-030 is kept separate from PR6424/00A-110 because the full suffix is a procurement and installation boundary. Verify the /006-030 cable termination and mechanical execution directly against the installed nameplate and dimensions.

Features
Large 16 mm sensing face for the PR6424 measurement geometry.
Static position and dynamic vibration capability within the family ranges.
Oil- and chemical-resistant PTFE cable construction.
Complete /006-030 suffix retained to avoid confusion with other PR6424 executions.
Applications
- Turbine and compressor shaft-vibration monitoring.
- Axial displacement measurement on large rotating equipment.
- Maintenance of installed PR6424/CON0x1 measurement chains.
Lifecycle
- Record the PR6424/006-030 label separately from every other PR6424 spare.
- Capture converter type, cable routing, mounting dimensions, target material and installed gap before disassembly.
- Protect the sensing tip and cable from impact, tight bends and connector contamination during installation.
- Complete gap, scale, runout, alarm and trip validation before returning the protection channel to service.
FAQ
Why is the /006-030 suffix important when ordering PR6424/006-030?
It is part of the exact configuration identity. The full label must be compared because other PR6424 variants may differ mechanically or at the cable termination.
Can PR6424/006-030 be mixed with any PR6424 converter?
No general interchangeability should be assumed. Confirm the converter type and the calibration relationship for the entire sensor-cable-converter chain.
What field measurements help validate PR6424/006-030 before removal?
Record the installed gap voltage, shaft runout, scale factor, alarm setpoints and any channel comparison data available during slow roll.
What handling damage is most important to avoid on PR6424/006-030?
Protect the sensing face, cable entry, PTFE cable and connector; crushing or over-bending the cable can invalidate an otherwise correct spare.
What proves the PR6424/006-030 channel is ready for service?
A documented mechanical gap, stable DC value, expected dynamic response, verified alarm/trip path and comparison with the approved machine baseline.
