Product Introduction
The Epro PR6426/000-100 32mm Eddy Current Sensor is a high-performance, non-contact displacement and vibration measurement device designed for industrial machinery monitoring. It is engineered to provide accurate and reliable detection of shaft vibration, axial displacement, and rotational movement in critical rotating equipment.
Utilizing the eddy current principle, the sensor generates an electromagnetic field at the probe tip. When a conductive target enters this field, the induced eddy currents alter the field, producing a voltage proportional to the distance from the target. This non-contact measurement method eliminates mechanical wear, enhances reliability, and ensures long-term stability even under harsh industrial conditions.
The PR6426/000-100 is compatible with Epro signal conditioning converters, providing linear output to monitoring systems for continuous machinery protection. Its 32mm sensor head diameter makes it suitable for monitoring larger shafts or broader target surfaces, ensuring high sensitivity and robust performance in turbines, compressors, generators, and other rotating machinery.
