Infrared thermometer care and maintenance methods
Infrared thermometer's main performance indicators are spectral response, response time, repeatability and emissivity. Fixed infrared thermometer for the glass and ceramic industry, paper and packaging industry, various types of kiln temperature measurement applications and the chemical industry to measure the temperature of instruments and other instruments, so as to detect the operational status of the instrumentation to ensure the normal operation of an instrument.
Factors that cause damage to the online pyrometer are as follows:
The first: moisture factor. Infrared thermometer is usually the case, some moisture, rain, dew and so on these are the factors that cause moisture, formed by the moisture dew is the main factor of outdoor humidity, dew caused by the hazards than the rain is greater, because it adheres to the material for a longer period of time, resulting in more serious moisture absorption. If the wood coating is washed away by rain to remove the surface aging layer, the unaged inner layer is exposed to sunlight, which produces further aging. In the infrared thermometer simulation test, moisture environment caused by the destruction mechanism of composite materials has been studied more clearly. Now take the diffusion of moisture to carbon fiber epoxy resin plywood as an example to illustrate the aging mechanism of humid atmospheric environment on composite materials.
The second: light factor. Infrared thermometer different products of the structural composition of the intensity of light is also different. For example, those durable materials, such as plastics, coatings, etc., these product materials meet the light, will not produce serious aging phenomenon. So to analyze the material composition of the product equipment is what.
The third: high temperature factor: when the environment because of high temperature and make the surrounding temperature rise, then it will make the intensity of light as well as the degree of destruction increased. Temperature and light do not have a direct chemical reaction, but there is a subtle connection between them. Therefore, when testing programmable infrared thermometers, it is necessary to grasp the precise temperature range.
The impact of these three factors on the product equipment is critical, any one of them, can quickly shorten the life of the thermometer time.
Infrared thermometer research shows that water-induced modulus reduction of epoxy resin is reversible. When the external environment is changed as well as the water diffuses out, the film volume of the resin can be restored almost to its original value. However, for many processes that absorb water, the water-induced property changes are again irreversible. Irreversible changes can lead to a significant reduction in the physical and mechanical properties of the material, while at the same time programmable infrared thermometers to simulate humid atmospheric conditions can detect the aging resistance of the material. Therefore, we should pay more attention to the details in the operation of the online pyrometer, in order to better utilize such instruments.
