The PR6426/010-140+CON021/916-200 is an eddy current sensor system manufactured by EPRO, which includes a sensor for the PR6426/010-140 model and a preprocessor for the CON021/916-200 model. This sensor system inherits EPRO’s valuable experience and related facilities in the field of rotating machinery protection and is widely used in various industrial measurement areas, such as turbomachinery monitoring, turbine monitoring and protection systems, and other industrial applications

The PR6426/010-140 sensor forms an oscillator with the presensor, and the amplitude of the attenuation is proportional to the distance between the sensor and the measured object as the sensor probe is close to the metal. The sensor and preprocessor have been linearly calibrated in complete sets using calibration material 42CrMo4 before delivery, so no calibration is required during installation. The user only needs to adjust the air gap between the sensor and the measuring surface until the desired signal is obtained from the output of the preprocessor

In addition, the PR6426/010-140 sensor provides high reliability, non-contact measurement and a wide range of adaptability, which can play an important role in industrial measurement, explosion-proof environment and other applications. It can also be integrated with various control systems to achieve automated control and optimized management, improving production efficiency and product quality
The CON021/916-200 preprocessor may provide signal conversion and amplification to ensure the accuracy and stability of the measurement data
