1. Introduction<\/strong><\/h3>\n

1.1 Pr\u00e9sentation du produit<\/b><\/strong><\/h4>\n

Le capteur de niveau radar KWL803 est conforme aux sp\u00e9cifications d\u00e9finies dans la norme nationale DB50\/T 826-2017 relative aux indicateurs de niveau. Son composant principal est con\u00e7u avec un \u00e9tanch\u00e9it\u00e9 IP68 enti\u00e8rement scell\u00e9e.
\nLa port\u00e9e maximale de mesure de ce produit atteint 40 m\u00e8tres, avec une zone morte minimale inf\u00e9rieure \u00e0 6 cm.
\nGr\u00e2ce \u00e0 sa fr\u00e9quence plus \u00e9lev\u00e9e et \u00e0 sa bande passante plus large, il offre une pr\u00e9cision sup\u00e9rieure. De plus, le produit est livr\u00e9 avec un support de fixation pour son installation.<\/p>\n

\"Installation<\/b><\/strong><\/h4>\n

1.2 Principe de d\u00e9tection<\/strong><\/h4>\n

Le capteur de niveau radar repose sur le principe de la r\u00e9flexion dans le domaine temporel (TDR). L'impulsion \u00e9lectromagn\u00e9tique se propage le long du c\u00e2ble ou de la sonde \u00e0 la vitesse de la lumi\u00e8re. Lorsqu\u2019elle rencontre la surface du milieu mesur\u00e9, une partie de l\u2019impulsion du capteur de niveau radar est r\u00e9fl\u00e9chie et forme un \u00e9cho qui revient vers l\u2019\u00e9metteur d\u2019impulsions en suivant le m\u00eame trajet ; la distance entre l\u2019\u00e9metteur et la surface du milieu mesur\u00e9 est directement proportionnelle au temps de propagation de l\u2019impulsion, ce qui permet de calculer la hauteur du niveau.<\/p>\n
