LEM - Infrared Sensor - Brand [Weikewei]

infra-redsensorThe application is becoming increasingly widespread, and it can be used for non-contact temperature measurement, such as gas composition analysis, non-destructive testing, thermal imaging detection, infrared remote sensing, and military target reconnaissance, search, tracking, and communication. InfraredsensorWith the development of modern science and technology, the application prospects will become even broader.

Temperature is a physical quantity that represents the degree of coldness or heat of an object, and it is the main indicator of the average kinetic energy of material molecules. Temperature is an important thermal quantity related to many physical phenomena and chemical properties of materials. Temperature measurement and control have important practical significance in scientific research and industrial and agricultural production.

There are many methods for temperature measurementInfrared temperature measurement58彩票It is a relatively advanced measurement method with the following characteristics.

58彩票 (1) Infrared temperature measurement can be used for long-distance and non-contact measurements. It is particularly suitable for temperature measurement of high-speed moving objects, charged bodies, high voltage, and high-temperature objects.

(2)Infrared temperature measurement58彩票Fast response speed. It does not require the process of reaching thermal equilibrium with the object, as long as it receives the target

58彩票Infrared radiation can measure the temperature of the target. The measurement time is generally in the millisecond to microsecond range.

58彩票 (3) Infrared temperature measurement has high sensitivity. According to Stefan Boltzmann's law, the radiation energy of an object is proportional to the fourth power of its temperature. A small change in the temperature of an object can cause a significant change in radiation energy, which can be quickly detected by an infrared detector.

(4)High accuracy of infrared temperature measurement. As it is a non-contact measurement, it will not affect the temperature distribution and motion state of the object, so the detected temperature is relatively accurate. Its measurement accuracy can reach over 0.19C, or even smaller.

58彩票 (5) Infrared temperature measurement has a wide range. It can measure temperatures ranging from several thousand degrees Celsius below zero to several thousand degrees Celsius above zero. Infrared temperature measurement can be used in almost all temperature measurement scenarios.
