It is based on the thermal radiation characteristics of the surface of the object, by detecting and analyzing the infrared radiation energy emitted by the object to determine the temperature of the object.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The temperature of an object determines the amount of infrared radiation energy emitted from its surface. Infrared temperature measurement utilizes the relationship between infrared radiation energy and the temperature of the object, and infers the temperature of the object by measuring the infrared radiation energy on the surface of the object. Infrared thermometry typically uses infrared sensors or thermal imaging cameras to capture the infrared radiation energy and convert it to a temperature value.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Infrared is a type of electromagnetic radiation with a wavelength between the wavelength of visible light and the wavelength of microwaves. According to Planck&#8217;s law of radiation and Stephen Boltzmann&#8217;s law, the infrared radiation energy of an object is proportional to its temperature. According to these laws, infrared temperature measurement can be used to deduce the temperature of an object by measuring the energy of infrared radiation on the surface of the object.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"549\" src=\"https:\/\/electricalwire.wiki\/wp-content\/uploads\/2023\/09\/cfa134b10bb647648dd2dbd9c51d0fb1-1024x549.jpg\" alt=\"\" class=\"wp-image-1273\" srcset=\"https:\/\/electricalwire.wiki\/wp-content\/uploads\/2023\/09\/cfa134b10bb647648dd2dbd9c51d0fb1-1024x549.jpg 1024w, https:\/\/electricalwire.wiki\/wp-content\/uploads\/2023\/09\/cfa134b10bb647648dd2dbd9c51d0fb1-300x161.jpg 300w, https:\/\/electricalwire.wiki\/wp-content\/uploads\/2023\/09\/cfa134b10bb647648dd2dbd9c51d0fb1-768x412.jpg 768w, https:\/\/electricalwire.wiki\/wp-content\/uploads\/2023\/09\/cfa134b10bb647648dd2dbd9c51d0fb1.jpg 1080w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Temperature measurement: infrared temperature measurement can be contact or non-contact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">-Contact infrared temperature measurement: contact infrared temperature measurement is the use of contact probes or probes and object surface contact, through heat conduction to measure the temperature of the object. This method is suitable for measurement scenarios that require direct contact with the surface of the object, such as measuring the temperature of a liquid.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Non-contact infrared thermometry: Non-contact infrared thermometry uses an infrared sensor or thermal imaging camera that does not require contact with the surface of the object. It calculates the temperature of an object by receiving and resolving the infrared radiation energy emitted by the object. This method is suitable for measurement scenarios that require long-distance measurements or where direct contact with the object is not possible, such as temperature measurements in high-temperature ovens, thermal management of electronic equipment, etc.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Application areas: Infrared temperature measurement is widely used in many fields, especially in industry and science. Commonly used in the following applications:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Industrial control and monitoring: Infrared temperature measurement can be used for temperature control and monitoring in industrial processes, such as metallurgy, glass manufacturing, petrochemical, welding, heating and cooling industries.<\/li>\n\n\n\n<li>Building and energy management: Infrared thermometry is used for building energy management, HVAC system regulation and fault detection.<\/li>\n\n\n\n<li>Medical Diagnostics: Infrared thermometry is used in the medical field to measure temperature, such as forehead temperature guns, temperature monitoring equipment, etc.<\/li>\n\n\n\n<li>Environmental monitoring: Infrared thermometry is used for environmental monitoring and meteorological studies, such as atmospheric temperature measurement and surface temperature monitoring.<\/li>\n\n\n\n<li>Household appliances: Infrared temperature measurement is also used in household appliances such as air conditioners, ovens and water heaters for temperature control and safety monitoring.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The accuracy of infrared temperature measurement is affected by a variety of factors, including environmental conditions, measurement distance, and object surface characteristics. When using infrared temperature measurement, you need to select the appropriate equipment and measurement method according to the specific requirements, and pay attention to the impact of calibration and environmental factors on the measurement results. In addition, different types of objects (metallic, non-metallic, liquid, etc.) respond differently to infrared radiation, so the effect of object characteristics on the measurement results must be considered in the application.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Infrared thermometry is a technology that uses infrared radiation to measure the temperature of an object&#8217;s surface.<\/p>\n","protected":false},"author":1,"featured_media":1271,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[196],"class_list":["post-1270","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-materials","tag-infrared-thermometry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>infrared thermometry - Electrical cable &amp;
