Advanced Eddy-Current Technology

The PR6424/006-030 operates on the proven principle of eddy currents. The sensor tip generates a high-frequency magnetic field; when a conductive metal shaft approaches this field, eddy currents are induced. This interaction alters the sensor's impedance, which is converted into a linear voltage signal proportional to the distance between the probe tip and the shaft . Because there is no physical contact, there is zero mechanical wear and no risk to the rotating equipment, ensuring long-term durability and maintenance-free operation.

Protect your most valuable rotating assets with the precision and durability of the Emerson EPRO PR6424/006-030. Ensure you pair it with the correct CON021 cable and signal conditioner for your specific application requirements.
