Overview

In response to the operating conditions of cement rotary kilns, such as high temperature, severe wear, and difficulty in temperature measurement, our company has invested a large amount of research and development funds, and combined with relevant foreign technologies to develop high-temperature alloy materials. We have made a special wear-resistant thermocouple protection tube, which adopts single and double layer two-level protection and achieves good performance. It can be used for a long time at a temperature of 1300 ℃, completely solving the problem of difficult temperature measurement in cement rotary kilns

Product Details

Details introduction:

Thermocouple（thermocouple）Yes, it isTemperature measuring instrumentThe commonly used temperature measuring element directly measures temperature and converts the temperature signal into a thermoelectric potential signal, which is then converted into the temperature of the measured medium through electrical instruments (secondary instruments). The appearance of various thermocouples often varies greatly due to their needs, but their basic structures are roughly the same. They are usually composed of main parts such as hot electrodes, insulation sleeves, and junction boxes, and are usually used in conjunction with display instruments, recording instruments, and electronic regulators.

Temperature is one of the important parameters that need to be measured and controlled in industrial production processes. Thermocouples are widely used in temperature measurement, with many advantages such as simple structure, convenient manufacturing, wide measurement range, high accuracy, low inertia, and easy remote transmission of output signals. In addition, as thermocouples are active sensors that do not require an external power source for measurement, they are very convenient to use and are often used to measure the temperature of gases or liquids in furnaces and pipelines, as well as the surface temperature of solids.

In response to the operating conditions of cement rotary kilns, such as high temperature, severe wear, and difficulty in temperature measurement, our company has invested a large amount of research and development funds, and combined with relevant foreign technologies to develop high-temperature alloy materials. We have made a special wear-resistant thermocouple protection tube, which adopts single and double layer two-level protection and achieves good performance. It can be used for a long time at high temperatures1300℃Completely solved the problem of difficult temperature measurement in cement rotary kilns.

Special high-temperature alloy wear-resistant thermocouples for rotary kilns are usually used in conjunction with display instruments, recording instruments, and electronic computers. It can directly measure the third stage cylinder, fourth stage cylinder, fifth stage cylinder, tertiary air duct, decomposition furnace, kiln tail smoke chamber, kiln hood, etc,600-1380℃The surface temperature of gas solids within the range is detected, and the product is widely used in major cement plants and related kiln industries and has been recognized.

2、 Product Features

3、 Working principle

Two homogeneous conductors with different compositions(Instant electrode)After welding, it forms a thermocouple, as shown in the figure. The welding end is the measuring end(Also known as the hot end)The end connected to the display instrument is called the reference end(Also known as the cold end)When there is a temperature difference between the measuring end and the reference end, the thermocouple outputs a thermoelectric potential. When connected to a display instrument, the instrument indicates the temperature value of the measuring end.
