The temperature measuring ring is a reliable high-precision product with recognized accuracy and reliability Ceramic temperature measuring rings can be placed almost anywhere in the kiln, inside the furnace body, on push plates or conveyor belts. The working principle of a ceramic temperature measuring ring is to provide the actual accumulated heat of the temperature measuring ring and the fired product based on its linear shrinkage within the working temperature range, and to obtain the test temperature by comparing it with the conversion table. When the ceramic temperature measuring ring is heated in the kiln, it contracts and continues to contract at the highest temperature as the insulation time increases. Within its temperature range of use, the shrinkage rate is linear, providing a practical measurement method for the heating amount received by PRCT ceramic temperature measuring rings and fired products. The shrinkage (decrease in ring diameter) can be measured using a digital micrometer.
