Infrared thermometer measurement application example
The application possibilities of different thermometers are extremely wide. The sharp price drop in recent years has opened up more and more fields of application, especially in low temperature areas or for replacing general traditional thermometers. The following examples are about the use and an overview of the answers.
1. Concrete processing industry
In the processing of concrete, the temperature plays a key role in the setting time and the resulting firmness. Especially for high-grade concrete, a certain processing temperature must be reached, and the contact probe will be damaged mechanically due to the corrosive action of the cement. . The thermometer can directly accept the temperature of the mixing drum, and it can also be the temperature at the concrete outlet. Because of the requirements of ISO9000 quality inspection, the temperature must be recorded in the form of a file together with other production parameters, which is suitable for dirty industries. The environment requires very strong, such as dust-proof and waterproof measuring lenses. In order to protect the thermometer, appropriate accessories such as axial gap nozzles, optical mirror protection covers and insulating tubes are used.
2. Paper industry
In paper refining, the paper track will run between a heated metal roll and a plastic-coated finish roll, and if the paper width is smaller than the roll width, the temperature at the edge of the finish roll will be much higher than that in the middle , the temperature difference between the middle and the edge cannot exceed the specified maximum temperature, otherwise the plastic coating will be damaged.
In order to measure the temperature, each rack can be equipped with three fixed thermometers, or a thermometer can be used to move along the length of the roll on the aimer device. Due to local strong steam, a waterproof thermometer and belt shaft are required. The gap nozzle is used for free blowing of the window, because the temperature processing requires an SPS machine, so the general instrument can be corrected with emissivity.
3. Ceramic industry
For the production of ceramic materials, it is necessary to know the temperature change process in the combustion process in order to achieve the same quality products and avoid waste products. At the same time, in order to save energy, the temperature must be controlled within the minimum value. So far, it has been measured with a thermometer. Temperature, what it gets is room temperature, and the thermometer has an advantage in this regard, it can directly measure the temperature of the surface of the object, and it is in a very short time, so that it can accurately measure and maintain the combustion temperature.
4. Metallurgical industry
In the metallurgical industry, infrared temperature measurement is used in various fields. For example, the diagnosis of inner wall defects of various furnace bodies, the diagnosis of stave damage, the control of process parameters, etc. Through infrared temperature measurement, the condition of equipment can be accurately monitored, the service life of equipment can be improved, energy can be saved, costs can be reduced, and product quality can be improved.
It can be seen that the traditional thermometer will be an obsolete product of the era. It will disappear or be damaged over time, so that it needs to be replaced continuously. However, the thermometer has no wear parts, so in theory, its service life is unlimited. Therefore, its more expensive investment cost can be won back in a short period of time. The thermometer can be installed on the side or on the top, avoid oblique alignment, so that the thermometer is only caught on the edge, and the axial gap nozzle should not be placed on the lens of the thermometer. temperature, an additional cooling device is required.
