Category: Nuevos Componentes , Industria y Noticias

Existen aplicaciones médicas en las que se necesita un sensor especial. Se trata de un sensor que mide el caudal de gases como el oxígeno, y otros que no son agresivos. Mouser Electronics ofrece este sensor de que tratamos en este artículo, basados ??en información directa del datasheet que puede ser accedido en: https://www.mouser.com/datasheet/2/682/Sensirion_Mass_Flow_Meters_SFM3200_Datasheet-1316565.pdf .

   El sensor SFM200 de Sensirion consiste en un sensor digital con salida I2C que mide el flujo de gases como el aire y el oxígeno, además de otros gases no agresivos para uso en aplicaciones médicas tales como ventilación, anestesia, medidas respiratorias, medidas de flujo inspiratorio y aplicación de drogas.

   El sensor utiliza la tecnología CMOSens® patentada por Sensirions que combina el elemento sensor, el procesamiento de señal y la calibración digital en un solo chip.

   El flujo de gas es medido por un elemento sensor térmico que permite obtener una respuesta muy rápida, con linealización y compensación de temperatura interna. En la figura 1 tenemos el aspecto y la pinza de este componente.

Sensirion asegura que esta tecnología facilita al OEM en el desarrollo de nuevos productos, proporcionando información en el datasheet SFM3200-AW.

    Además de los recursos de los que ya tratamos el sensor posee además un amplificador, convertidor A / D, memoria EEPROM, circuitos de procesamiento de señal e interfaz.

      En la tabla abajo tenemos algunas informaciones sobre el desempeño de este sensor.

 

  Las características eléctricas se dan en la tabla siguiente.
