El term\u00f3metro de globo<\/strong> est\u00e1ndar consiste en una esfera de cobre pintada de negro<\/strong> con un di\u00e1metro de 150 mm y un espesor de 0,4 mm.<\/p>\r\n\r\n\r\n\r\n

Contiene un term\u00f3metro con el bulbo <\/strong> en el centro de la esfera. Este sensor se describe en la norma ISO 7726. El principal objetivo de la medici\u00f3n de la temperatura de la esfera en las aplicaciones meteorol\u00f3gicas es la posibilidad de estimar la temperatura radiante media (Tmrt), que es uno de los par\u00e1metros meteorol\u00f3gicos m\u00e1s importantes que rigen el equilibrio energ\u00e9tico humano y el confort t\u00e9rmico humano en mediciones microclim\u00e1ticas.<\/p>\r\n\r\n\r\n\r\n

      \r\n\u00bfPara qu\u00e9 sirve un term\u00f3metro de globo negro?<\/summary>\r\n

      Un term\u00f3metro de globo mide la temperatura de globo negro, una magnitud que combina los efectos de la temperatura del aire, la ventilaci\u00f3n y la radiaci\u00f3n t\u00e9rmica. Esta medici\u00f3n es \u00fatil para evaluar de forma m\u00e1s realista la carga t\u00e9rmica percibida por las personas y para estimar la temperatura radiante media.<\/p>\r\n<\/details>

      \r\n\u00bfPor qu\u00e9 es importante el term\u00f3metro de globo negro para calcular los \u00edndices microclim\u00e1ticos?<\/summary>\r\n

      La radiaci\u00f3n t\u00e9rmica puede modificar de forma significativa la percepci\u00f3n del calor incluso cuando la temperatura del aire permanece constante. La temperatura de globo se utiliza directamente en el c\u00e1lculo del WBGT y permite estimar la temperatura radiante media, necesaria para \u00edndices como PMV\/PPD y UTCI. Por lo tanto, una medici\u00f3n fiable mejora la representatividad de toda la evaluaci\u00f3n microclim\u00e1tica.<\/p>\r\n<\/details>

      \r\n\u00bfEl term\u00f3metro de globo tnegro ambi\u00e9n puede utilizarse en smart cities y en aplicaciones de Health & Safety?<\/summary>\r\n

      S\u00ed. En las smart cities puede instalarse en zonas peatonales, plazas, parques, escuelas e infraestructuras urbanas para monitorizar la exposici\u00f3n al calor y analizar los efectos de la isla de calor urbana. En el \u00e1mbito de Health & Safety, ayuda a evaluar el estr\u00e9s t\u00e9rmico de los trabajadores en obras, plantas industriales, almacenes y puestos de trabajo exteriores, donde la radiaci\u00f3n solar o el calor generado por los procesos puede aumentar el riesgo.<\/p>\r\n<\/details>

      \r\n\u00bfQu\u00e9 caracter\u00edsticas hacen fiable el term\u00f3metro de globo de LSI LASTEM?<\/summary>\r\n

      El sensor utiliza una esfera negra de cobre de 150 mm con el elemento sensible situado en el centro, siguiendo la configuraci\u00f3n descrita en la norma ISO 7726. Ofrece una precisi\u00f3n declarada de 0,1 \u00b0C, una superficie de alta absortividad, protecci\u00f3n IP66 y opciones de integraci\u00f3n mediante se\u00f1ales 4\u201320 mA o Modbus-RTU. Adem\u00e1s, LSI LASTEM dispone de un laboratorio interno acreditado seg\u00fan ISO\/IEC 17025 para las mediciones de temperatura.<\/p>\r\n<\/details><\/div>\r\n","protected":false},"excerpt":{"rendered":"
