Abstract

Un método para operar un dispositivo de detección de gas que incluye un sensor de gas electroquímico limitado por capilaridad incluye operar el sensor de gas en un modo de detección durante el cual una señal del sensor de gas es representativa de una concentración del gas analito medida por el sensor de gas y en un modo de interrogación durante el cual el sensor de gas es interrogado electrónicamente aplicando una señal eléctrica al sensor de gas para generar un flujo de corriente no faradaica entre un electrodo de trabajo y un contraelectrodo sin la aplicación de un gas de prueba, entrando periódicamente en el modo de interrogación, medir un parámetro de la salida de un sensor de gas durante el modo de interrogación, comparar el parámetro medido con uno o más parámetros medidos previamente, determinar un estado operativo a partir de la comparación y devolver el sensor de gas al modo de detección si se determina que el estado operativo está dentro de un rango predeterminado.
