Working principle of temperature measuring ring
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.
Installation of silicon molybdenum rod
The silicon molybdenum bar is somewhat softened at high temperature (above 1500 ℃), and hard and brittle at low temperature. In order to avoid stress during temperature change and facilitate Thermal expansion of components, the free vertical hanging installation method is adopted. The disassembly and replacement of lifting components is also more convenient, and there is no need to wait for the furnace to cool down, but can be heat exchanged. When hanging silicon molybdenum rods, the following precautions must be taken:
Silicon molybdenum rod electric heating element products
Silicon molybdenum bar electric heating element products are widely used in metallurgy, steelmaking, glass, ceramics, refractories, crystals, electronic components, semiconductor materials research, production and manufacturing and other fields, especially for the production of high-performance precision ceramics, high-grade artificial crystals, precision structure metal ceramic, glass fiber, Optical fiber and high-grade alloy steel.

Advantages of non-contact temperature measurement in the glass industry
The non-contact temperature measurement technology in the glass industry is an important physical measurement method in all industrial fields of temperature measurement. This is also a necessary means of production process control in the glass industry. Non contact temperature measurement is constantly receiving attention due to its advantages: ——Easy to operate; ——Fast response time; ——Not aging, with minimal drift; ——Flexible configuration and reasonable price; ——It will not contaminate the glass solution.
Temperature measuring rings are widely used for temperature measurement in kilns
Ceramic products require accurate and effective temperature measurement in production, but most measurement methods and tools are limited in time and space. For example, thermocouples cannot measure the temperature of the product itself, but rather the ambient temperature at which the product is fired. In addition, it can only measure radiant heat and does not involve heat transfer from kiln furniture. Ceramic temperature measuring ring is a high-precision ceramic temperature indicator that faithfully records the thermal process experienced by the product during the firing process. Ceramic temperature measuring rings not only measure radiant heat and radiant heat, but also consider the impact of temperature over time. Ceramic temperature measuring rings can conveniently represent the heating process with a simple number - ring temperature (RT), making it easy to apply in practical work. Suitable for continuous and non continuous tunnel kilns, shuttle kilns, roller kilns, bell jar kilns, etc. It is recommended to use multi position and multi level placement, which can give you the most direct understanding of the heat content inside the kiln. At the same time, the PTCT temperature measuring ring can be used in different firing atmospheres such as oxygen, nitrogen, air, vacuum, and reduction.
Acting as an agent for temperature measuring rings and coins in the UK
In January 2014, it officially represented and distributed temperature measuring rings and coins from Mantec in the UK
