Abstract

Transducteur composite pour la mesure d'une grandeur physique telle que température, pression, niveau de liquide, débit d'écoulement, concentration d'un constituant gazeux dans un mélange de gaz ou densité de flux neutronique. Le signal de sortie d'un détecteur à réponse rapide, mais à précision médiocre, est combiné avec le signal de sortie d'un détecteur à réponse lente, mais à bonne précision, pour engendrer un signal de sortie de transducteur dont le délai de réponse est comparable à celui du détecteur à réponse rapide et dont la précision est égale à celle du détecteur à réponse lente. Parmi de nombreuses applications possibles, on peut citer la surveillance de la densité de flux neutronique dans le coeur d'un réacteur nucléaire.
