Multispectral Sensor Application Possibility Research for Temperature Control in the Carbon Black Production

Paper focuses on the possibility research of using the APDS-9960 sensor as a radiation receiver for a high-temperature spectral ratio pyrometer. The application efficiency coefficients calculations results of APDS-9960 and TCS34725 sensors are presented. The various channels signals ratio dependences of the APDS-9960 sensor on temperature and quantization errors are calculated. It was found that when using an additional IR filter, the APDS-9960 sensor has a higher efficiency coefficient and a quantization error 1.5 times less than TCS34725. The field tests results of an experimental spectral ratio pyrometer with an APDS-9960 sensor are considered.
