Ceramic temperature measuring ringWorking principle:The working principle of the calibration ring is based on the fact that the calibration ring undergoes contraction when absorbing heat (linear contraction occurs within the working temperature range of the calibration ring), in order to provide the actual accumulated heat of the calibration ring and the burned product, and compare it with the conversion table to obtain the test temperature. The temperature calibration ring can be placed in any position inside the kiln, such as on kiln furniture, kiln carts, or loading plates, or placed together with the fired products. The shrinkage rate of the diameter of the calibration ring accurately reflects the actual temperature at which the calibration ring is located in the kiln. It is easy to measure the diameter of the temperature calibration ring after firing using a common micrometer caliper. For correct and convenient use, each batch of temperature calibration rings is accompanied by a dedicated conversion table. Please note that the production batch number marked on the temperature calibration ring must be consistent with the temperature conversion table for correct use.
Product advantages:1. The placement of the temperature calibration ring should be close to the actual heating state of the product, and the heating condition of the burned product should be accurately measured;
2. The use of the temperature calibration ring is flexible and flexible, making it easy to measure any corner of the three-dimensional space inside the furnace;
3. The consistency of the temperature calibration ring is good, which can ensure the good reproducibility of the product firing system, thereby improving the qualification rate of the finished product;
4. The use of temperature calibration rings can reduce or even eliminate the need for measurement or destructive testing of the geometric shape, density, and porosity of fired products, thereby reducing quality control costs in the production process.
5. Correct temperature difference: ± 1.5 ℃ for the same batch.

Attention:The calibration temperature loop is measured based on the accumulated heat during the entire firing process, including radiation heat, conduction heat, convection heat, and the comprehensive effect of different insulation times. Not only can it measure the highest temperature reached by the fired product, but it can also accurately represent the entire true heating state of the product during the heat treatment process.
