Il s’agit de deux param\u00e8tres statistiques qui sont utilis\u00e9s pour repr\u00e9senter la fiabilit\u00e9 des composants (\u00e9lectroniques). Toutefois, les param\u00e8tres MTTF et MTBF ne doivent pas \u00eatre confondus avec la dur\u00e9e de vie moyenne.<\/p>\n

Pour les capteurs et les transmetteurs de pression, les valeurs MTTF sont normalement utilis\u00e9es car ces instruments ne sont g\u00e9n\u00e9ralement pas r\u00e9par\u00e9s, mais compl\u00e8tement remplac\u00e9s.<\/p>\n
