Factors that cause damage to infrared thermometer products
The main performance indicators of infrared thermometers include spectral response, response time, repeatability, and emissivity. Fixed infrared thermometers are used in glass and ceramic industries, papermaking and packaging industries, various kiln temperature measurement applications, and chemical industry to measure the temperature of instruments and meters, so as to detect the operating status of instruments and meters and ensure the normal operation of an instrument. run.
The first type: moisture factor
Generally, some humidity, rain, dew, etc. are the factors that cause humidity. Dew formed by moisture is the main factor of outdoor humidity. Dew is more harmful than rain because it adheres to the material. The longer the time, the more serious moisture absorption will be caused. For example, the surface aging layer of the wood coating is removed by rain washing, and the unaged inner layer is exposed to sunlight, resulting in further aging. In the infrared thermometer simulation test, the damage mechanism of composite materials caused by humid environment has been studied clearly. Taking the diffusion of moisture to carbon fiber epoxy resin laminates as an example, the aging mechanism of composite materials in humid atmospheric environment is illustrated.
The second type: light factor
The structure and composition of different products of infrared thermometers also vary in the intensity of light. For example, those durable materials, such as plastics, paints, etc., these product materials will not produce serious aging when exposed to light. Therefore, it is necessary to analyze the material composition of the product equipment.
The third type: high temperature factor
When the ambient temperature rises due to high temperature, the intensity of light 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 precise temperature range.
These three factors are crucial to the impact of product equipment, any one of them can quickly shorten the service life of the thermometer.
