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

1.1 Productoverzicht<\/b><\/strong><\/h4>\n

De KWL803 radarniveausensor voldoet aan de specificaties die zijn vastgelegd in de nationale norm DB50\/T 826-2017 voor niveaumeters. Het belangrijkste onderdeel is ontworpen met een volledig afgedichte IP68-waterdichting.
\nHet maximale meetbereik van het product bedraagt 40 meter, met een minimale dode hoek van minder dan 6 cm.
\nDankzij de hogere frequentie en bredere bandbreedte biedt het een superieure nauwkeurigheid. Daarnaast wordt het product geleverd met een vaste beugel voor de montage.<\/p>\n

1.2 Werkingsprincipe<\/strong><\/h4>\n

De radarniveausensor werkt volgens het principe van tijddomeinreflectie (TDR). De elektromagnetische puls verspreidt zich met de snelheid van het licht langs de kabel of de sonde. Wanneer de puls het oppervlak van het gemeten medium raakt, wordt een deel van de puls van de radarniveaumeter gereflecteerd en keert deze als een echo via hetzelfde pad terug naar de zender. De afstand tussen de zender en het oppervlak van het gemeten medium is recht evenredig met de voortplantingstijd van de puls, waardoor de hoogte van het niveau kan worden berekend.<\/p>\n
