Infrared temperature measurement technology has played an important role in the production process, in product quality control and monitoring, equipment online fault diagnosis and safety protection, and energy saving. In the past 20 years, non-contact infrared human body thermometer have been rapidly developed in technology, performance has been continuously improved, functions have been continuously enhanced, varieties have been continuously increased, and the scope of application has also continued to expand. Compared with the contact temperature measurement method, infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long service life. The non-contact fever sensor includes three series: portable, online and scanning, and is equipped with various options and computer software. There are various models and specifications in each series. Among various types of thermometers with different specifications, it is very important for users to choose the correct infrared thermometer model.
With the development of science and technology, the traditional contact temperature measurement method cannot meet the temperature measurement needs of some modern fields, and the demand for non-contact and remote temperature measurement technology is increasing. The common temperature measurement technology has been nearly mature after a long time of development. At present, with the economic development, the temperature measurement technology under special conditions (such as high temperature, strong corrosion, strong electromagnetic field conditions or a long distance) is increasingly needed.
Non-contact infrared temperature measurement is also called radiation temperature measurement. Generally, thermoelectric or photoelectric detectors are used as detection elements. This fever sensor is relatively simple, it can realize temperature measurement in a large area, or it can be thermometer at a certain point on the measured object; it can be portable or fixed, and it is easy to use; its manufacturing process is simple Low temperature, no contact with the measured object during temperature measurement, which has a series of advantages such as short response time, no interference with the measured temperature field, long service life, and convenient operation. The influence of external factors such as temperature distance, soot and water vapor has a large measurement error.
In this infrafred temperature measurement technology, the choice of infrared temperature sensor is very important, and not only the infrared temperature sensor is used in the spot temperature measurement, but also the infrared temperature sensor can be used for large-area temperature measurement. The temperature measurement technology of infrared temperature sensor has the advantages of high temperature resolution, fast response speed, no disturbance of the temperature distribution field of the measured target, high measurement accuracy and good stability; in addition, there are many types of infrared temperature measurement and development Very fast, the technology is relatively mature.
