EMERSON EPRO • PR6424 SERIES
PR6424/003-030
16 mm Eddy Current Displacement Sensor
Precision Monitoring for Large Rotating Machinery
The PR6424 series uses non-contact eddy-current measurement for radial and axial shaft displacement, position, eccentricity and speed/key-related monitoring on large rotating shafts. PR6424 is intended for shaft diameters of 80 mm and above.

|
01 / PRODUCT PROFILE
Designed for Large Shafts
PR6424/003-030 belongs to the PR6424 16 mm eddy current sensor family. The non-contact sensing principle is suited to continuous monitoring of rotating machinery where direct mechanical contact with the shaft is undesirable. The PR6424 family is intended for large shafts and can be used for radial and axial dynamic displacement, shaft position, eccentricity and speed/key-related measurements. Typical Machinery
Steam turbines • Gas turbines • Hydro turbines • Compressors • Pumps • Fans

PR6424 FAMILY
Large-Shaft Sensing
|
The PR6424 belongs to the PR642x eddy current sensor family. Within the family, sensor variants are selected according to shaft size, installation arrangement, temperature requirements, cable configuration and measuring-chain requirements. PR6424 is the 16 mm sensor choice for large shafts of 80 mm diameter and above.

|
03 / APPLICATION CONDITIONS
Where the Sensor Adds Value
Shaft displacement monitoring
Continuous non-contact measurement of radial or axial movement on large rotating shafts.
Position and eccentricity
Useful where changes in shaft position or eccentricity need to be observed as part of machinery-condition monitoring.
Speed / key-related measurements
The sensor family can support speed and key-related measurements when correctly integrated into the measuring chain.

|
Q1. Is PR6424/003-030 the right replacement when the existing sensor is a 16 mm PR6424?
It can be a suitable replacement only when the installed mechanical configuration, sleeve length, cable arrangement, connector arrangement and measuring chain requirements correspond to the PR6424/003-030 configuration. The complete installed chain should be checked before ordering.
|
Q2. Can PR6424/003-030 be used on large turbine or compressor shafts?
Yes. PR6424 is designed for large shafts, with a recommended shaft diameter of at least 80 mm. It is intended for radial and axial shaft displacement, position, eccentricity and related speed/key measurements in critical rotating machinery.
|
|
Q3. Does PR6424/003-030 require a matching converter?
The PR6424 sensor operates as part of a measuring chain with a compatible converter or transmitter. Emerson identifies CON-series converters for PR642x sensors. The replacement should therefore be checked against the converter already installed in the machine.
|
Q4. What should be checked if PR6424/003-030 gives an abnormal shaft reading?
Check the sensor-to-target gap, target surface and material, sensor mounting, cable condition, connector condition and the associated converter. The complete measuring chain should be evaluated before replacing the sensor alone.
|
|
Q5. Why is PR6424/003-030 useful for critical machinery monitoring?
Its non-contact eddy-current principle allows shaft displacement to be monitored without mechanical contact with the rotating surface. The PR6424 family provides a 4 V/mm sensitivity and a ±2.0 mm static measurement range, supporting condition-monitoring tasks on large rotating machinery.
