製品紹介
The Epro PR6426/000-111 32mm Eddy Current Sensor is a precision-engineered, non-contact measurement device designed for critical industrial machinery monitoring. It provides accurate detection / shaft vibration, axial displacement, and rotational movement, ensuring the reliable performance / turbines, compressors, generators, and other rotating equipment.
The sensor operates on the eddy current principle, where a high-frequency electromagnetic field is generated at the sensor tip. When a conductive target enters this field, eddy currents are induced, altering the field and generating a voltage proportional to the distance between the target and the sensor. This non-contact approach eliminates mechanical wear, enhances long-term reliability, and maintains measurement stability even in harsh industrial environments.
With a 32mm sensor head diameter, the PR6426/000-111 is suitable for monitoring larger shafts or broader target surfaces. It integrates with Epro signal conditioning converters, providing a linear output compatible with industrial monitoring and control systems, making it ideal for predictive maintenance programs and real-time machinery protection.
