Het hart van elk Brookfield viscositeitsinstrument wordt gevormd door een zorgvuldig ontworpen veer die ontworpen is om de viscositeit van vloeistoffen en visco-elastische materialen met ongeëvenaarde nauwkeurigheid te meten.
Deze instrumenten werken volgens het principe van roterende viscositeitmeting, waarbij gebruik wordt gemaakt van het koppel dat nodig is om een spindel in een vloeistof in beweging te houden aan een vast toerental.
Hoe werkt een viscositeitsmeting?
Onderdompeling
Het Brookfield instrument dompelt een spindel of sonde onder in de vloeistof. De geometrie van de spindel en de snelheid van rotatie bepalen het bereik en nauwkeurigheid van de viscositeitsmeting.
Rotatie
De spindel wordt in beweging gebracht in de vloeistof aan een vaste snelheid. De viscositeit van het materiaal creëert weerstand tegen vloei, die gemeten wordt in termen van koppel.
Berekening
Nauwkeurige sensoren controleren continu het koppel en de rotatiesnelheid. Het instrument berekent vervolgens de viscositeitswaarde in real-time op basis van de gemeten weerstand.
Resultaat
De viscositeitsmeting wordt weergegeven op een gebruiksvriendelijke interface, computer of touch screen, waarop de gebruiker onmiddellijk inzicht krijgt in het viscositeitsgedrag van zijn stalen.
