Présentation du produit
The Epro PR6453/201-SDR 12.5mm Eddy Current Sensor is a precision non-contact displacement and vibration transducer developed for high-performance industrial condition monitoring systems. It belongs to the Epro PR6453 series, a family sur eddy current sensors optimized for accurate detection sur shaft displacement, axial position, and vibration in rotating machinery.
This sensor operates on the eddy current measurement principle, generating a magnetic field that interacts with the conductive target surface. The resulting change in impedance is translated into an analog signal proportional to the distance between the probe tip and the target. The PR6453/201-SDR combines high resolution, stable signal output, and robust construction, making it ideal for use in harsh environments where precision and reliability are crucial.
Designed for use with compatible Epro signal converters such as CON021 or CON041, this sensor surfers seamless integration with advanced monitoring systems like the Epro MMS series. With a 12.5 mm sensing head, it provides a balance between compact design and measurement range, enabling accurate monitoring sur small or medium-sized shafts in turbines, compressors, motors, and other critical rotating machines.
