Information

Overview Manuals Technical notes Product Applications Mechanical Mounting

Features:

  • 8mm Eddy Current Sensor
  • Non-contact sensor
  • High-Precision Displacement Measurement
The Emerson (EPRO) PR6423/010-040 is a non-contact 8mm eddy current sensor system typically paired with the CON021 signal converter. It is engineered for critical turbomachinery applications—such as turbines, compressors, and gearboxes—to measure radial/axial shaft displacement, position, and speed.

The PR6423/010-040 Epro 8mm Eddy Current Sensor may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
PR6423/010-040 8mm Eddy Current Sensor Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The Emerson EPRO PR6423/010-040 is an 8mm Eddy Current Sensor designed for high-precision, non-contact measurement of radial and axial shaft displacement, vibration, and position in rotating machinery (such as turbines, compressors, and pumps).  The /040 designation typically signifies specific armor or connector configurations; some models are designed with armored cables for enhanced protection. 
  • Turbines: Steam, gas, and hydro turbines
  • Compressors: Both centrifugal and axial types
  • Pumps: Critical process pumps, including reactor coolant pumps
  • Fans & Blowers: Large industrial draft fans and blowers
  • Gearboxes: High-speed industrial gear units

Determine Nominal Gap: The standard nominal gap for the PR6423 8mm sensor is approximately 1.5 mm (0.06 in).
Target Requirements: The target surface should be ferromagnetic steel (standard: 42 Cr Mo 4) and have a diameter of at least 25 mm (0.98 in) to minimize measurement errors.
Thread & Sleeve: Use the M10x1 or 3/8"-24-UNF threads to secure the sensor into the machine housing or bearing cap.
Locking: Once the air gap is set (verified by voltage output from the converter), use the lock nuts to secure the sensor in place
