Produkteinführung
The Epro PR6426/000-140 32mm Eddy Current Sensor is a high-precision, non-contact monitoring device developed for industrial machinery applications. It is designed to measure shaft vibration, axial displacement, and rotational position in turbines, compressors, generators, and other critical rotating equipment, ensuring safe and efficient operation.
The sensor operates based on the eddy current principle, generating an electromagnetic field at its probe tip. When a conductive target, such as a steel or nickel-alloy shaft, enters this field, eddy currents are induced in the target. These currents modify the electromagnetic field, and the sensor produces a voltage output proportional to the target’s distance. This non-contact measurement method eliminates mechanical wear, ensures long-term reliability, and maintains stable performance under harsh industrial conditions.
With a 32mm sensor head diameter, the PR6426/000-140 is well-suited for large shafts and broad surface targets. It works seamlessly with Epro signal conditioning converters, delivering linear output suitable for real-time condition monitoring and predictive maintenance systems.
