Technical Overview
The CON021 + PR6424/010-100 system forms a complete displacement measurement chain. The probe generates a high-frequency electromagnetic field at the sensing tip. When positioned near a rotating shaft, variations in the air gap alter the eddy current distribution, producing measurable impedance changes.
These variations are transmitted to the CON021 signal conditioner, which converts them into a linear analog signal compatible with machinery monitoring systems. This architecture allows real-time shaft vibration and displacement analysis, forming a key layer of predictive maintenance strategy in high-value industrial equipment.
