Produkteinführung
The Epro PR6426/000-041 32mm Eddy Current Sensor is a high-precision, non-contact measurement device designed for industrial machinery monitoring. This sensor is specifically engineered to measure shaft vibration, axial displacement, and rotational position in critical rotating equipment. It is widely used in turbines, compressors, generators, and other machinery where accurate and reliable monitoring is essential for predictive maintenance.
The PR6426/000-041 operates on the eddy current principle, generating an electromagnetic field at the sensor tip. Conductive targets, such as steel shafts, alter this field, producing a voltage proportional to displacement. This non-contact method eliminates mechanical wear, ensures long-term reliability, and allows the sensor to operate in harsh environments.
With a 32mm sensor head diameter, the device is ideal for larger shafts or wider target surfaces, providing consistent measurement accuracy. The sensor is compatible with Epro’s standard signal conditioning converters, allowing integration with monitoring systems for continuous machinery protection.
