Emerson PR6424/011-140 Eddy Current Sensor

Product Overview

The Emerson PR6424/011-140 eddy current sensor is designed for non-contact measurement of shaft vibration and displacement in rotating machinery. These sensors are essential components in machinery protection and monitoring systems, where accurate measurement of mechanical movement is necessary for safe operation.

By using eddy current technology, the sensor can detect small changes in distance between the probe and a conductive target surface. This capability allows it to measure vibration, position, and displacement with high precision.

Measurement Principle

Eddy current sensors operate by generating a high-frequency electromagnetic field. When a conductive object enters this field, eddy currents are induced within the object. Changes in these currents alter the impedance of the sensor coil, allowing the system to determine the exact distance between the probe and the target.

This method provides reliable measurement without physical contact, making it ideal for monitoring high-speed rotating equipment.
