Présentation du produit
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 sur shaft vibration, axial displacement, and rotational movement, ensuring the reliable performance sur 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.
