Product Introduction
The CON021 + PR6424/01 system is a precision displacement measurement solution designed for industrial rotating machinery protection. The 16 mm probe generates a high-frequency electromagnetic field at its tip. As shaft position changes, eddy currents induced in the conductive surface alter the probe impedance. These changes are processed by the CON021 converter into proportional analog signals.
In high-value assets such as turbines and compressors, this system plays a critical role in early fault detection, helping prevent excessive vibration, misalignment, and catastrophic mechanical failure.
