System Functional Overview
The CON021 + PR6424/007-110-CN configuration forms a complete eddy current displacement measurement chain. The probe generates a high-frequency electromagnetic field at the sensor tip. Variations in the distance to a conductive shaft cause measurable changes in impedance, which are converted by the CON021 into a proportional analog signal.
This system is widely used in predictive maintenance and protective shutdown architectures, where early detection of shaft vibration, eccentricity, or axial displacement is essential to preventing catastrophic equipment failure.
