Product Introduction
The Epro PR6426/000-110 32mm Eddy Current Sensor is a high-precision, non-contact measurement device specifically designed for industrial machinery monitoring and condition assessment. It accurately detects shaft vibration, axial displacement, and rotational movement in critical rotating equipment, making it an essential tool for predictive maintenance and machinery protection.
Operating on the eddy current principle, this sensor generates an electromagnetic field at the probe tip. When a conductive target, such as a steel shaft, enters this field, eddy currents are induced in the target, altering the electromagnetic field. The resulting voltage is proportional to the distance between the sensor and the target. This non-contact measurement eliminates mechanical wear, ensures long-term reliability, and maintains stable performance in harsh industrial environments.
The PR6426/000-110 features a 32mm sensor head diameter, making it suitable for larger shafts or broader target surfaces. It integrates seamlessly with Epro signal conditioning converters, providing linear output for continuous monitoring systems in turbines, compressors, generators, and other rotating machinery.
