Emerson PR6424/000-030 PR6424 16 mm Eddy Current Sensor
A non-armored M18 × 1.5 PR6424 sensor configured with an adapter plug, 8 m cable and LEMO end.
Product Profile
Emerson PR6424/000-030 is a 16 mm eddy-current sensor for critical turbomachinery. Its first suffix group identifies the M18 × 1.5 thread, no armor and Cx 40 mm sleeve option; the resulting documented total sensor dimension C is Cx plus 12.5 mm.
The second suffix group selects the adapter plug, 8 m total cable length and LEMO cable end. These cable and mechanical choices distinguish this execution from other PR6424 variants.
Technical Data
System Role
Non-contact eddy-current sensing avoids mechanical loading of the rotating target.
The PR6424 family is intended for radial and axial dynamic displacement, position, eccentricity and speed/key measurement.
The documented converter family and target material remain part of the calibrated measurement chain.
The complete six-position suffix controls mechanical and cable options and must not be shortened during procurement.
Compatibility & Service
- Record the complete PR6424 suffix, converter type, target material and installed air gap.
- Do not mix cable or connector executions merely because the sensor family matches.
- Protect the coaxial connector and observe the documented cable bend limits during routing.
- After replacement, confirm static gap, sensitivity, polarity and monitor-channel alarms with the approved procedure.
Applications
- Steam-, gas- and hydro-turbine shaft monitoring.
- Compressor, pump and fan vibration or position measurement.
- Large-shaft installations requiring a 16 mm eddy-current sensor.
- Maintenance of an existing PR6424 measurement chain with the same mechanical and cable execution.
FAQ
Q01What differentiates PR6424/000-030 from PR6424/002-010?+
The 000 execution uses the shorter Cx 40 mm sleeve and an 8 m cable, while 002 uses Cx 60 mm and a 5 m cable. Both dimensions affect installation and cannot be interchanged from the family name alone.
Q02Which chain details should accompany a PR6424/000-030 enquiry?+
Provide the converter model, target material, installed gap, mounting bracket, cable route, connector type and complete sensor label.
Q03Can the 8 m cable on PR6424/000-030 be shortened in the field?+
Do not change the configured sensor cable as an ordinary wiring adjustment; the complete sensor and converter chain must retain its documented electrical configuration.
Q04Why is the target material important for PR6424/000-030?+
Eddy-current calibration depends on target conductivity and material. Confirm the machine target and converter setup before accepting a replacement.
Q05What should be tested after installing PR6424/000-030?+
Verify mechanical clearance, static gap, output polarity, sensitivity, dynamic response and the associated monitor alarm or protection logic.
