Product Introduction
The PR6423-11R-111+CON031 EPRO provides the critical interface between physical rotor movement and the electronic protection system. By generating a high-frequency electromagnetic field, the sensor detects microscopic changes in the gap between the probe tip and the shaft. The CON031 converter then linearizes this physical distance into a standardized voltage signal, which the monitoring rack uses to calculate vibration levels or axial “float.”
As a senior engineer, I want to emphasize that the “11R-111” portion of the model number defines the physical build—specifically the thread type, mounting length, and pigtail connector. The PR6423-11R-111+CON031 EPRO is a factory-calibrated chain; the CON031 is tuned to compensate for the specific impedance of the probe’s integral cable. This ensures the output maintains a precise 8 V/mm (or similar) slope, which is essential for accurate machinery diagnostics.
