Product Introduction
The PR6423-003-030+CON021 EPRO serves as the “eyes” of a turbine protection system. By establishing a high-frequency electromagnetic field, the probe detects the smallest variations in the gap between its tip and the rotating shaft. The CON021 driver then linearizes this physical displacement into a standardized voltage signal, which is interpreted by the monitoring rack to trigger alarms or emergency trips if vibration limits are exceeded.
As a senior engineer, I want to highlight the “030” designation in the model number, which indicates a 3.0-meter integral cable length. This is a factory-calibrated system length. Using a PR6423-003-030+CON021 EPRO ensures that the impedance of the cable is perfectly matched to the driver’s circuitry, maintaining the strict 8 V/mm (or similar) slope required for accurate machinery diagnostics.
