Emerson PR6426-000-030 is pr6426 large-range eddy-current displacement sensor. It senses shaft-to-probe displacement for a matched Emerson signal converter and machinery-monitoring channel.
- Provides an eight-millimetre nominal static span
- Mounts through an 80 x 40 mm plate
- Uses an eight-metre unarmored lead
- Connects to a PR6426-calibrated converter
PR6426-000-030 operates with PR6426-configured CON021 or CON041, 80 x 40 mm mounting plate, Large conductive target, Compatible position-monitoring channel.
Engineered applications include Large axial-displacement measurement, Valve and actuator position, Large-clearance shaft position, Slow mechanical movement monitoring.
Important Notice: Verify mounting-plate flatness, the eight-metre cable system and PR6426 converter calibration; set the larger gap only after the target and bracket are mechanically stable.

Apter Power PR6426-000-030 Measurement-System Technical Reference PDFApter Power PR6426-000-030 Installation, Loop Check and Acceptance Workbook PDFThe first document provides model-specific technical and measurement-system reference data. The second is a separate field workbook for mounting, wiring, commissioning and acceptance records.
Large axial-displacement measurement
Measures displacement where a wider static span is required.
Valve and actuator position
Tracks controlled movement of large conductive targets.
Large-clearance shaft position
Supports large-clearance shaft-position observation.
Slow mechanical movement monitoring
Provides non-contact measurement of slow expansion or movement.
Read the applicable Emerson machinery-monitoring instructions before work. Verify PR6426-000-030 and the installed Emerson PR6426 32 mm eddy-current measurement system configuration.
1
Verify the complete PR6426-000-030 order code, 80 x 40 mm mounting plate mounting interface and assigned PR6426 32 mm eddy-current system measuring point before work.
2
Place the monitored machine and its protection channel in the approved maintenance state before disturbing PR6426-000-030.
3
Protect the probe tip from impact and keep the mounting thread and bracket free from burrs or contamination.
4
Route the 8 m sensor lead without sharp bends, crushing, tensile load or contact with hot and moving surfaces.
5
Keep the LEMO or open-end connection clean, dry and fully identified before reconnecting the measurement loop.
6
Confirm the paired signal converter or monitor input, cable length and target material match the documented measuring chain.
7
Set the static gap within the documented linear region while preserving shaft and probe mechanical clearance.
8
Prove polarity, static gap, dynamic response and alarm action before returning the protection channel to service.
Technical notes
Verify mounting-plate flatness, the eight-metre cable system and PR6426 converter calibration; set the larger gap only after the target and bracket are mechanically stable.
FAQ View All FAQ
-
What measurement or system function does PR6426-000-030 perform?PR6426-000-030 is a pr6426 large-range eddy-current displacement sensor. It senses shaft-to-probe displacement for a matched Emerson signal converter and machinery-monitoring channel.
-
Which installed hardware must be paired with PR6426-000-030?Use PR6426-000-030 with the documented Emerson PR6426 32 mm eddy-current measurement system components: PR6426-configured CON021 or CON041, 80 x 40 mm mounting plate, Large conductive target.
-
How should the Sensor family value for PR6426-000-030 be verified?Confirm the complete nameplate and order code before work; the documented sensor family is PR6426.
-
What connection detail is critical when installing PR6426-000-030?Preserve every conductor, connector and shield identity, then follow the model-specific connection arrangement described in the controlling Emerson document.
-
How is PR6426-000-030 mechanically installed without changing measurement behavior?Protect the probe tip from impact and keep the mounting thread and bracket free from burrs or contamination.
-
What commissioning test should be completed for PR6426-000-030?Prove polarity, static gap, dynamic response and alarm action before returning the protection channel to service.
-
What configuration record should be retained when replacing PR6426-000-030?Retain the as-found position, sleeve thread, cable or channel identity, gap or scaling value, diagnostics and final functional-test result.
-
Can PR6426-000-030 replace a similar Emerson model without engineering review?No direct substitution should be assumed; verify the full order code, measuring function, interface, cable or channel arrangement and the approved Emerson PR6426 32 mm eddy-current measurement system configuration.
