Infrared thermometer maintenance and maintenance methods
The main performance indicators of infrared thermometers are spectral response, response time, repeatability and emissivity. Fixed infrared thermometers are used in glass and ceramic industries, paper and packaging industries, various furnace temperature measurement applications, and chemical industries to measure the temperature of instruments and meters, so as to detect the operating status of instruments and meters and ensure normal operation. A musical instrument.
The factors that lead to the damage of the online thermometer are as follows:
The first is the humidity factor. Infrared thermometers Usually, some moisture, rain, dew, etc. are all factors that cause humidity. Dew formed by moisture is the main factor affecting outdoor humidity. Dew is more harmful than rain because it sticks to materials. longer, resulting in more severe hygroscopicity. For example, wood coatings are washed away by rain, removing the surface aging layer, and the unaged inner layer is exposed to sunlight, causing further aging. In the infrared temperature measurement simulation test, the damage mechanism of the composite material in the humid environment was clearly studied. Taking the diffusion of water to carbon fiber epoxy resin laminates as an example, the aging mechanism of composite materials in humid atmospheric environment is expounded.
The second: lighting factor. The structure and composition of different infrared thermometer products also have different effects on the light intensity. Such as plastics, coatings and other durable materials, these product materials will not cause serious aging under the light. Therefore, it is necessary to analyze what the material composition of the product equipment is.
The third: high temperature factor: When the ambient temperature increases due to high temperature, the light intensity and the degree of damage will increase. There is no direct chemical reaction between temperature and light, but there is a subtle connection between them. Therefore, when testing programmable infrared thermometer products, it is necessary to grasp the accurate temperature range.
These three factors are critical to the impact of product equipment, any of which can quickly shorten the life of a thermometer.
Infrared thermometer studies have shown that the water-induced reduction in the modulus of epoxy resins is reversible. When the external environment changes and the water diffuses outward, the film-forming amount of the resin can almost return to its original value. However, for many water absorption processes, the property changes induced by water are irreversible. The irreversible changes will lead to a significant decrease in the physical and mechanical properties of the material, while a programmable infrared thermometer that simulates a humid atmospheric environment can detect the anti-aging properties of the material. Therefore, we should pay more attention to details when operating online thermometers, so as to make better use of these instruments.
