SERIES CONTEXT
PR6424 family
 
The PR6424 family is the 16 mm sensor platform within Emerson's PR642x eddy-current measurement range. Different PR6424 variants can use different configuration, cable and measurement-chain arrangements.
PR6423
8 mm-class eddy-current sensor family used where a smaller sensing diameter is appropriate.
Different physical sensor class from PR6424.
PR6424
16 mm eddy-current platform with a 4 V/mm sensitivity specification and a nominal center air gap of approximately 2.7 mm.
The PR6424/00A-110 belongs to this family.
PR6426
A separate PR642x sensor family used for larger measurement ranges and corresponding measurement-chain configurations.
Selection depends on the machinery geometry and required range.
Configuration note: PR6424 variants should not be treated as interchangeable solely because the base family number is the same. Probe configuration, cable arrangement, converter compatibility and the required measurement range should be checked against the installed measurement chain before replacement.

BUYER QUESTIONS
PR6424/00A-110 FAQ
Can PR6424/00A-110 replace another PR6424 variant directly?
Not automatically. PR6424 variants can differ in probe configuration, cable arrangement and measurement-chain requirements. The installed converter and complete probe-chain configuration should be checked before a replacement is selected.
What machinery measurements can PR6424/00A-110 support?
The PR6424 platform is intended for non-contact measurement of radial and axial shaft dynamic displacement, shaft position, eccentricity and speed/key applications in critical rotating machinery.
What should be checked before ordering PR6424/00A-110 for an existing system?
Check the complete installed chain: probe variant, cable arrangement, converter compatibility, target material, required measurement range and the mechanical installation geometry. These factors determine whether a particular PR6424 configuration is suitable.
Why does the PR6424/00A-110 configuration matter for machinery replacement work?
Eddy-current systems operate as a matched measurement chain. A probe with the same family number may still have a different configuration. Matching the installed arrangement helps avoid mechanical or electrical mismatch during maintenance.
What performance characteristics make PR6424/00A-110 suitable for demanding rotating equipment?
The PR6424 family provides 4 V/mm sensitivity, ≤ ±1.5% sensitivity/linearity, approximately 2.7 mm nominal center air gap, ±2.0 mm static range, 0–1,000 μm dynamic range and a long-term drift specification below 0.3%. These characteristics support precision shaft-displacement monitoring in appropriate measurement-chain installations.
