Abstract

Un sensor de gas electroquímico que presenta un elemento sensible a la temperatura tal como un termistor dispuesto dentro del sensor de gas en unaforma aislante de temperatura para evitar cualquier variación en la temperatura de los gasesaplica dos a ser sensados y a ser direccionados inmediatamente alelemento sensible a la temperatura proporcionando por lo tanto senales de compensación de temperatura ajustadas para ser combinadas con las senales desalida eléctricas generadaspor el s ensor. El elemento sensible de temperatura o termistor está montado en un sumidero de calor a una membrana de expansióndel sensor de gas que responde unicamente a los cambios en las variaciones de temperatura impartidas por elelectrolito de senso r y no por las variaciones dela temperatura del cuerpo del sensor de gas y elementos asociados por lo cual proporciona senales de compensación de temperatura correctas sin demoras detiempo que producen errores.
